Further, the detonation side receiving antenna 11 (11A, 11B, 11C) of the wireless detonator 10 corresponds to the ignition tool side receiving antenna, and the detonating side transmitting antenna 18 corresponds to the igniting tool side transmitting antenna.

● [Overall configuration of wireless crushing system 1 (FIG. 1) and loading state of parent die 36A and additional die 36B into charge hole 40 (FIG. 2)]
As shown in FIG. 1, in the radio crushing system 1, the parent die 36A and the expansion die 36B (FIG. 1) are loaded into the charging hole 40 to which the radio detonator is attached and drilled in the face surface 41 (explosion blasting location). 2), the detonator operating device 50, the relay device 51, the detonating operator side transmitting antenna 60, and the detonating operating device side receiving antenna 65.

The detonation operation device 50 is arranged at a remote position away from the charging hole 40, and supplies a current to the detonation operation device side transmission antenna 60 via the detonation bus 62, the relay device 51, and the auxiliary bus 61 to perform the detonation operation. A magnetic field is generated around the machine-side transmitting antenna 60, and a control signal (details of the control signal will be described later) is superimposed. Therefore, the detonation operating device 50 wirelessly transfers the driving energy, the ignition energy, and the control signal of the electronic circuit 120 of the wireless detonator tube 10 to the wireless detonator tube 10 via the transmission antenna 60 on the detonation operating device side. .. The wireless detonator 10 receives the driving energy, the ignition energy, and the control signal of the electronic circuit 120 in a wireless manner via the detonating side receiving antenna 11 (see FIG. 10). The frequency of the current flowing through the detonator-side transmitting antenna 60 for passing the driving energy and the ignition energy, and the operating frequency, which is the frequency of the control signal, are, for example, 100 [kHz] or more and 500 [kHz] or less. It is set. If the operating frequency is higher than 500 [kHz], standing waves are likely to be generated in the tunnel, which is not very preferable.

Further, the detonation operation device 50 transmits the radio response signal from the detonation side transmission antenna 18 (see FIG. 2) of the radio detonator tube 10 to the detonation operation device side receiving antenna 65, the detonation operation device side receiving antenna cable 66, and the relay device. Received via 51 and the burst bus 62. The response frequency, which is the frequency of the response signal from the wireless detonator 10, is set to, for example, 100 [MHz] or more and 1 [GHz] or less. If the response frequency is set higher than 1 [GHz], it is difficult to transmit through the bedrock, which is not very preferable. The response frequency is 500 [kHz] or higher, and the output of the response signal is very small compared to the drive energy, ignition energy, and control signal output of the electronic circuit, and a stationary wave is generated. There is no problem because the receiving antenna on the detonation operation device side can be installed optimally.

The relay device 51 has a tuning circuit, and is provided between the detonation operation device 50 and the detonation operation device side transmission antenna 60, and between the detonation operation device 50 and the detonation operation device side reception antenna 65. There is. The relay device 51 is connected to the detonation operating device 50 via the detonation bus 62, connected to the detonation operating device side transmitting antenna 60 via the auxiliary bus line 61, and detonated via the detonation operating device side receiving antenna cable 66. It is connected to the receiving antenna 65 on the machine side. When the relay device 51 passes the driving energy of the electronic circuit, the ignition energy, and the control signal from the detonation operation device 50 to the wireless detonation lightning tube 10, the drive energy and ignition of the electronic circuit from the detonation operation device 50. A control signal including energy for use is output to the transmission antenna 60 on the detonation operation machine side via the auxiliary bus 61. Further, when the relay device 51 receives the response signal transmitted from the wireless detonation lightning tube 10 to the detonation operation device 50, the relay device 51 receives the response signal from the wireless detonation lightning tube 10 with the detonation operation device side receiving antenna 65 and the detonation operation device side. It is received via the antenna cable 66 and delivered to the detonation operation device 50.

The detonator-side transmitting antenna 60 is located near the face surface 41 (charge hole) and is stretched around the face or the outer circumference of the face, and the distance L1 is, for example, about 0 [m] to 1 [m] from the face surface 41. It is stretched in a loop along the cave bed 42, the cave side wall 43, and the cave ceiling 44 at positions separated by (corresponding to the first predetermined distance). The distance L3 from the relay device 51 to the face surface 41 is, for example, about 50 [m]. The distance L4 from the relay device 51 to the detonation operating device 50 is, for example, about 100 [m] to 300 [m]. The transmitting antenna 60 on the detonation operation device side and the auxiliary bus 61 are newly stretched each time the explosion is performed.

The receiving antenna 65 on the detonation operating device side is, for example, a pole-shaped antenna, and is arranged at a position separated from the face surface 41 (the location of the bombing) by a distance L2 (corresponding to a second predetermined distance). For example, the distance L2 is set to 0 [m] to 100 [m]. Since the response frequency of the response signal received from the wireless detonator 10 is 100 [MHz] or more and 1 [GHz] or less, the shape is significantly different from that of the detonator side transmitting antenna 60, and it is necessary to wind it in a loop shape. There is no. The receiving antenna 65 on the detonation operator side and the cable 66 for the receiving antenna on the detonation operating device side are not replaced each time they are detonated if the distance L2 from the bombed location is a certain distance.

As shown in FIG. 2, the parent die 36A and the expansion die 36B, which are explosives, are loaded into the charge hole 40 to form the explosive unit 20. The charge hole 40 is, for example, a hole having a diameter D1 of about 5 [cm] and a depth D2 of about 2 [m], but is not limited to this value. Then, as shown in FIG. 2, the charging hole 40 is loaded with the parent die 36A and the expansion die 36B, and is covered with a sealing material 22 such as clay. In this case, the parent die 36A is a leading explosive when loaded into the charge hole 40, and is an explosive to which the radio detonator 10 is attached. Further, the increase die 36B is an explosive that is appropriately increased or decreased with respect to the parent die 36A in this case.

As shown in FIG. 2, the wireless detonator 10 is composed of a substantially cylindrical detonation side receiving antenna 11, a control unit 12, an detonation unit 14, and an detonation side transmission antenna 18, for example, a control unit 12. And the detonation unit 14 are housed in the detonation side receiving antenna 11. Further, the inner diameter of the substantially cylindrical detonating side receiving antenna 11 is formed to be larger than the outer diameter of the explosive. The explosive is inserted into the detonating side receiving antenna 11 and the detonating portion 14 is inserted, integrated with the detonating side receiving antenna 11 to form a parent die 36A, and loaded into the charging hole 40. Further, the outer diameter of the detonation side receiving antenna 11 is equal to or smaller than the inner diameter of the charge hole 40. As shown in the example of FIG. 12, only the detonation unit 14 may be housed in the detonation side receiving antenna 11, and the control unit 12 may be arranged outside the detonation side receiving antenna 11.

Further, the display device 72 displays individual information (for example, detonation delay time and identification number) capable of identifying the wireless detonator 10 by an operator, and is attached to the wireless detonator 10 via a cable 71. .. The length of the cable 71 is set so that the display device 72 can reach the outside of the charging hole 40 when the parent die 36A is loaded into the charging hole 40. Therefore, as shown in FIG. 2, the display device 72 is arranged outside the charging hole 40 when the parent die 36A is loaded into the charging hole 40. The cable 71 and the display device 72 may be omitted. Further, in the description of the present embodiment, the example in which the display device 72 is attached to the wireless detonator tube 10 via the cable 71 has been described, but the display device 72 may be directly attached to the wireless exploding lightning tube 10. When the display device is directly attached to the wireless detonator, the operator cannot check the display device after loading it in the charge hole, but when loading it in the charge hole, load it while checking the display device. Can be done.

In the following explanation, the influence of the positional relationship between the detonation operation device side antenna (detonation operation device side transmission antenna, detonation operation device side reception antenna) and the wireless detonation lightning tube antenna (detonation side reception antenna, detonation side transmission antenna). Regardless of this, it is possible to receive the driving energy, ignition energy, and control signal of the electronic circuit more efficiently, and the degree of freedom in selecting the response frequency of the response signal is high, so that the response signal can be transmitted efficiently. The details of the radio detonation tube 10 which is more compact and can be made smaller will be described.

● [Direction of magnetic field generated around the transmitting antenna 60 on the detonator side (FIGS. 3 to 5)]
FIG. 3 is a diagram in which only the detonator-side transmitting antenna 60 is extracted from FIG. 1. In FIG. 3, when a current flows through the transmitting antenna 60 on the detonation operating device side in the direction of the arrow of the solid line, a magnetic field as shown by the alternate long and short dash line is generated. The detonating side receiving antenna 11 of the wireless detonating lightning tube 10 is most efficiently used for driving energy and ignition of an electronic circuit when a conductive wire is wound around the axis when the direction of this magnetic field is used as an axis. It is possible to receive energy and efficiently receive radio control signals.

Note that FIG. 4 is a view of FIG. 3 from the IV direction. The position of the charging hole of the face surface 41 corresponding to the center of the wound detonator side transmitting antenna 60 is indicated by the charging position P2b. The position corresponding to the edge of the detonator-side transmitting antenna 60 and the upper left position of the charging position P2b is indicated by the charging position P1a, and the position corresponding to the edge of the detonator-side transmitting antenna 60. The upper right position of the charge position P2b is indicated by the charge position P1c, and the position corresponding to the edge of the detonator side transmitting antenna 60 and the upper position of the charge position P2b is the charge position. Shown on P1b. Further, the position corresponding to the edge of the detonator-side transmitting antenna 60 and the left position of the charging position P2b is indicated by the charging position P2a, which corresponds to the edge of the detonator-side transmitting antenna 60. The position on the right side of the charge position P2b is indicated by the charge position P2c. Further, the position corresponding to the edge of the detonator-side transmitting antenna 60 and the lower left position of the charging position P2b is indicated by the charging position P3a, which corresponds to the edge of the detonator-side transmitting antenna 60. The position on the lower right side of the charge position P2b is indicated by the charge position P3c, and the position corresponding to the edge of the detonator side transmitting antenna 60 and the position below the charge position P2b is the charge. Shown at position P3b.

FIG. 5 shows a magnetic field (generated around the detonator side transmitting antenna 60) at each of the charging positions P1a to P1c, the charging positions P2a to P2c, and the charging positions P3a to P3c of the face surface 41 shown in FIG. It is a figure which shows the example of the direction and the magnitude of the magnetic field (magnetic field). At the charge position P2b corresponding to approximately the center of the detonator side transmitting antenna 60, the magnetic field component is only in the Z-axis direction, so an antenna in which a conductive wire is wound around the Z-axis (Z-axis in the example of FIG. 8). The Z-axis tubular antenna (Z-axis receiving antenna 11Z) made of the tubular coil 119 and the tubular magnetic material can efficiently receive the driving energy and the ignition energy of the electronic circuit. However, in the vicinity of the edge of the detonator side transmitting antenna 60, the magnitude of the magnetic field in the Z-axis direction decreases, and the magnitude of the magnetic field in the X-axis direction and the magnetic field in the Y-axis direction increases. For example, at the charge position P3c, the magnitude of the magnetic field in the Z-axis direction is smaller than that of the charge position P2b, and the magnitudes of the magnetic field in the X-axis direction and the magnetic field in the Y-axis direction are larger than the magnitude of the magnetic field in the Z-axis direction. Further, at the charge position P1b, the magnitude of the magnetic field in the Z-axis direction is smaller than that of the charge position P2b, and the magnitude of the magnetic field in the Y-axis direction is larger than the magnitude of the magnetic field in the Z-axis direction. Therefore, at the charging positions P1a to P1c, the charging position P2a, the charging position P2c, and the charging positions P3a to P3c, which are the positions of the edges of the detonator side transmitting antenna 60, the conductive wire is wound around the Z axis. Only with the rotated antenna (in the example of FIG. 8, the Z-axis tubular coil 119 and the Z-axis tubular antenna (Z-axis receiving antenna 11Z) made of a tubular magnetic material), the energy and ignition for driving the electronic circuit are efficiently generated. It is not always possible to receive the energy and the radio control signal efficiently. Therefore, by using the detonation side receiving antenna 11 described below, even if the detonating side receiving antenna is arranged (loaded) in the charge hole drilled at any position on the face surface 41, it is more efficient. The detonation side receiving antenna 11 that can receive the driving energy and the ignition energy of the electronic circuit and can efficiently receive the radio control signal is realized.

Further, when the detonator receiving antenna 11 of the wireless detonator 10 is also used as an antenna for transmitting a response signal transmitted from the wireless detonator 10 to the detonator, the response frequency is less than 100 [MHz]. The reach of the response signal is short (for example, about several [m]), which is not very preferable. Further, when the response frequency is higher than 1 [GHz], it is easily absorbed by the bedrock, which is not so preferable. When the response frequency is 100 [MHz] or more and 1 [GHz] or less, it is difficult to be absorbed by the bedrock, and a response signal having an appropriate reach can be obtained. However, the detonation side receiving antenna 11 capable of efficiently receiving the control signal (including the driving energy and the ignition energy of the electronic circuit) having an operating frequency of 100 [kHz] or more and 500 [kHz] or less is 100 [MHz]. When it is attempted to be used as the detonation side transmitting antenna capable of efficiently transmitting a response signal having a response frequency of 1 [GHz] or less, the size of the antenna becomes large and the inside of the charging hole 40 shown in FIGS. 1 and 2 is used. It may not be possible to load.

The inventor of the present application has a radio detonator having a detonator receiving antenna 11 and a detonating side transmitting antenna 18 as separate antennas in order to realize a radio detonator that satisfies all of the following (1) to (3) (FIG. 6. Invented FIG. 7).
(1) A control signal (including driving energy and ignition energy of an electronic circuit) having an operating frequency of 100 [kHz] or more and 500 [kHz] or less can be efficiently received from the detonation operating device.
(2) A response signal having a response frequency of 100 [MHz] or more and 1 [GHz] or less can be efficiently transmitted to the detonation manipulator.
(3) It is a size that can be loaded into a charge hole having a diameter of about 5 [cm] and a depth (depth) of about 2 [m].

● [Structure of wireless detonator 10 (Figs. 6 to 12)]
FIG. 6 shows a radio detonator 10 having a detonator transmitting antenna 18 provided at a position where the control unit 12 is projected to the outside of the detonating receiving antenna 11 and is projected at a position where the control unit 12 is not in contact with the detonating receiving antenna 11. It is a perspective view which shows the example (the 1) of the appearance of. FIG. 7 shows an example of the appearance of the radio detonator 10Z in which the detonation side transmitting antenna 18 is provided at a position protruding to the outside of the detonating side receiving antenna 11 and at a position not in contact with the detonating side receiving antenna 11 (No. 2). It is a perspective view which shows. Further, FIG. 8 shows an exploded perspective view of the radio detonator 10 shown in FIG. When the response frequency is set to 100 [MHz] or more and 1 [GHz] or less, the detonating side transmitting antenna 18 can be realized by, for example, an antenna of about several [cm] printed on a flat surface of an electronic circuit board. There is (see FIG. 20). Therefore, the detonation side transmission antenna 18 can be provided at the position shown in the example of FIG. 6 or at the position shown in the example of FIG. 7, and the detonation side transmission antenna 18 can be integrated with the wireless detonator. Is easy. In the example of FIG. 6, the detonation side transmitting antenna 18 is connected to the control unit 12 by a conductive wire or integrated with the control unit 12 (see FIG. 28). Further, in the example of FIG. 7, the detonating side transmitting antenna 18 is connected to the control unit 12 by a conductive wire 111.

The wireless detonator 10 is connected to the detonation side receiving antenna 11, the detonating side transmitting antenna 18, the detonating side receiving antenna 11 and the detonating side transmitting antenna 18, and the control unit 12 that ignites the detonating unit 14 and the control unit 12. It is composed of a connected detonator unit 14. An electronic circuit 120 is housed in the control unit 12 (see FIGS. 11 and 12). Further, FIG. 9 is a view of the detonating side receiving antenna 11 in FIG. 8 as viewed from the IX direction in FIG. As shown in FIG. 13, for example, the detonation side receiving antenna 11 has a tubular base cylinder 114 (for example, a tubular acrylic material) and a sheet-shaped magnetic material (for example, ferrite) as a thin tubular base. A tubular magnetic body 115 wound around the outer circumference of the tubular body 114, and a tubular coil (Z-axis tubular coil 119) and a sheet coil 117 (X-axis sheet-shaped coil) provided on the outer circumference of the tubular magnetic body 115. 117X and a Y-axis sheet-shaped coil 117Y) are arranged coaxially. As for the detonation side receiving antenna 11, three Z-axis cylindrical coils 119, an X-axis sheet-shaped coil 117X, and a Y-axis sheet-shaped coil 117Y are arranged along the Z-axis direction. The shape of the detonating receiving antenna 11 is preferably a thin cylinder, but it may be a thin cylinder, and the cross section orthogonal to the axial direction (Z-axis direction) is a circle, an ellipse, a polygon, or the like. , It may have any shape. Further, the detonation side receiving antenna 11 and the control unit 12 are connected by a conductive wire 111.

Further, FIG. 10 shows a cross-sectional view of the radio detonator 10 shown in FIG. The detonation unit 14 is fixed to the control unit 12, and the control unit 12 is fixed to one opening of the detonation side receiving antenna 11. A part of the control unit 12 projects outward from the detonation side receiving antenna 11, and the detonation side transmitting antenna 18 is provided at the protruding position and at a position not in contact with the detonating side receiving antenna 11. The gap between the detonating receiving antenna 11 and the control unit 12 is preferably filled with the explosive. As a result, the explosive can be placed deep inside the charge hole, so that the crushing effect can be improved. The detonator 14 is fixed so as to extend toward the other opening, and when the explosive is inserted through the other opening, the detonator 14 is inserted into the tip of the inserted explosive, and the parent die with a wireless detonator tube is inserted. Explosives are formed.

Further, FIG. 11 shows an example of a cross-sectional view of a radio detonator 10A having a configuration different from that of FIG. 10, in which the control unit 12 and the detonator unit 14 are housed in the detonation side receiving antenna 11. In the example shown in FIG. 11, the detonating side receiving antenna 11, the tubular magnetic body 115, and the base tubular body 114 are coaxially arranged and formed in a tubular shape. A control unit 12 to which the detonation unit 14 is fixed is fixed to one of the openings with, for example, an adhesive 161. Further, the control unit 12 is composed of a control case 162, an electronic circuit 120 (an electronic circuit indicated by reference numeral 120 in FIG. 27), a cushioning material 163, and the like. Further, in the example of FIG. 11, the detonating side transmitting antenna 18 is integrated with the electronic circuit 120 (see FIG. 28). A part of the control unit 12 projects outward from the detonation side receiving antenna 11, and the detonation side transmitting antenna 18 is provided at the protruding position and at a position not in contact with the detonating side receiving antenna 11. The detonator 14 is fixed so as to extend toward the other opening, and when the explosive is inserted through the other opening, the detonator 14 is inserted into the tip of the inserted explosive, and the parent die with a wireless detonator tube is inserted. Explosives are formed. Further, by forming the control case 162 with a material such as a resin having relatively high strength and easily transmitting radio waves and using an appropriate cushioning material 163, it was generated when the explosive arranged in the adjacent charge hole was detonated. It is also possible to prevent the shock wave from being damaged by the control case 162 and the cushioning material 163 before being transmitted to the electronic circuit 120.

Further, FIG. 12 shows a cross section of a radio detonator 10B having a configuration different from that of FIGS. 10 and 11 in which the detonation unit 14 is housed in the detonation side receiving antenna 11 and the control unit 12 is arranged outside the detonation side receiving antenna 11. An example of the figure is shown. In the example shown in FIG. 12, the detonating side receiving antenna 11, the tubular magnetic body 115, and the base tubular body 114 are arranged coaxially, and are further housed in the tubular protective case 165. Further, the protective case 165 has an isolation wall 166 that separates the detonation unit 14 and the control unit 12 from the explosive. The control unit 12 is located on the side opposite to the detonation unit 14 with the isolation wall 166 in between, and is not inside the detonation side receiving antenna 11 but outside the detonation side receiving antenna 11. The control unit 12 may be fitted and fixed to one opening of the protective case 165, or may be fixed to one opening of the protective case 165 with an adhesive or the like. Further, the control unit 12 is the same as the example shown in FIG. 11 in that the control case 162 is composed of the control case 162, the electronic circuit 120, the cushioning material 163, and the like. Further, in the example of FIG. 12, the detonating side transmitting antenna 18 is integrated with the electronic circuit 120 (see FIG. 28). The control unit 12 projects outward from the detonation side receiving antenna 11, and the detonation side transmitting antenna 18 is provided at the protruding position and at a position not in contact with the detonating side receiving antenna 11. Then, as in the example of FIG. 11, the detonating portion 14 is fixed so as to extend toward the other opening, and when the explosive is inserted through the other opening, the detonating portion 14 is inserted into the tip of the inserted explosive. As a result, an explosive for the parent die with a radio detonator is formed. Further, by forming the control case 162 with a material such as a resin having relatively high strength and easily transmitting radio waves, a shock wave generated when the explosive arranged in the adjacent charge hole detonates is transmitted to the electronic circuit 120. It can also be previously damped by the control case 162 and the cushioning material 163 to prevent damage to the electronic circuit 120. Further, by arranging a part of the control case 162 outside the detonating receiving antenna 11, the size of the electronic circuit 120 can be made larger than the inner diameter of the base cylinder 114, which is the size of the electronic circuit 120. The degree of freedom is improved. Further, the area through which the explosive is inserted is expanded, and the crushing effect can be improved.

● [Structure of the detonating side receiving antenna 11 and the detonating side transmitting antenna 18 (FIGS. 13 to 20)]
FIG. 13 shows an exploded perspective view of the detonation side receiving antenna 11. The detonation side receiving antenna 11 is an antenna that wirelessly receives the driving energy, the ignition energy, and the control signal of the electronic circuit. The detonation side receiving antenna 11 is composed of a base tubular body 114, a tubular magnetic body 115, an X-axis sheet-shaped coil 117X, a Z-axis tubular coil 119, and a Y-axis sheet-shaped coil 117Y. Has been done. The base cylinder 114 may be omitted.

The material of the tubular magnetic material 115 is a material having a high magnetic permeability in which the magnetic poles disappear or invert relatively easily among the magnetic materials, for example, iron, silicon steel, permalloy, sendust, permenzur, ferrite. , Amorphous magnetic alloy, nanocrystal magnetic alloy, etc. are preferable, and ferrite is used in this embodiment. As shown in FIG. 13, the tubular magnetic body 115 is formed in a sheet shape, and is wound around the outer peripheral surface of the base tubular body 114 to form a thin tubular body. As shown in FIG. 14, it is more preferable that the winding end portion of the tubular magnetic material 115 is wound so that the gap 172 becomes almost zero without overlapping. However, as shown in FIG. 13, one end of the winding of the tubular magnetic material 115 may be wound so as to overlap the other end and have an overlap portion 171 or to have a tubular magnetism. The body 115 may be wound so as to be double or triple. The gap 172 shown in FIG. 14 is within the permissible range if it is a minute gap of, for example, about 1 [mm], but it is not preferable if the gap 172 is larger than the minute gap. Further, as shown in FIGS. 8 and 13, the antenna axis J11, which is the axis of the tubular magnetic body 115, is parallel to the Z axis and can be said to be the Z axis.

Then, as shown in FIG. 13, the Z-axis tubular coil 119, the X-axis sheet coil 117X, and the Y-axis sheet coil 117Y are attached so as to be coaxial with the base tubular body 114 and the tubular magnetic body 115. The detonation side receiving antenna 11 is formed. The detonating side receiving antenna 11 is loaded into the charging hole so that the antenna shaft J11, which is the axis of the detonating side receiving antenna 11, coincides with the axial direction (in this case, the Z-axis direction) of the charging hole 40. Then, with respect to the magnetic field of the component in the Z-axis direction in FIG. 5, the Z-axis tubular coil 119 having the Z-axis direction as the winding axis of the conductive wire and the Z-axis tubular antenna made of a tubular magnetic material ( The Z-axis receiving antenna 11Z (see FIGS. 6 and 7) can efficiently receive the driving energy and the ignition energy of the electronic circuit, and can efficiently receive the radio control signal. Further, with respect to the magnetic field of the component in the X-axis direction in FIG. 5, the sheet-shaped coil 117X for the X-axis having the winding axis of the conductive wire in the X-axis direction and the sheet-shaped antenna for the X-axis (X) made of a tubular magnetic material. The shaft receiving antenna 11X (see FIGS. 6 and 7) can efficiently receive the driving energy and the ignition energy of the electronic circuit, and can efficiently receive the wireless control signal. Further, with respect to the magnetic field of the component in the Y-axis direction in FIG. 5, the sheet-shaped coil 117Y for the Y-axis having the Y-axis direction as the winding axis of the conductive wire and the sheet-shaped antenna for the Y-axis using a tubular magnetic material (Y). The shaft receiving antenna 11Y (see FIGS. 6 and 7) can efficiently receive the driving energy and the ignition energy of the electronic circuit, and can efficiently receive the wireless control signal. Examples shown in FIG. 13 include a base cylinder 114, a tubular magnetic material 115, a Z-axis tubular coil 119, an X-axis sheet coil 117X, and a Y-axis sheet coil 117Y. Although an example in which the detonation side receiving antenna 11 is configured is shown, the base cylinder 114 may be omitted.

As shown in FIGS. 6 and 7, the detonation side receiving antenna 11 has three antennas, that is, the Z-axis receiving antenna 11Z, the X-axis receiving antenna 11X, and the Y-axis receiving antenna 11Y, in the Z-axis direction. It is formed by arranging them in any order so as not to overlap with each other. In the examples of FIGS. 6 and 7, the Z-axis receiving antenna 11Z is a Z-axis cylindrical antenna (Z-axis receiving) using a Z-axis cylindrical coil 119 and a tubular magnetic material 115 (corresponding to the first magnetic material). It is configured as an antenna 11Z). The X-axis receiving antenna 11X is configured as an X-axis sheet-shaped antenna (X-axis receiving antenna) composed of an X-axis sheet-shaped coil 117X and a tubular magnetic material 115 (corresponding to a second magnetic material). The Y-axis receiving antenna 11Y is configured as a Y-axis sheet-shaped antenna (Y-axis receiving antenna) using a Y-axis sheet-shaped coil 117Y and a tubular magnetic material 115 (corresponding to a third magnetic material). The first magnetic material, the second magnetic material, and the third magnetic material may be configured separately, or may be configured as a common magnetic material as shown in the present embodiment.

According to the results of various experiments by the inventor, the Z-axis tubular coil 119 is arranged in the center (the position where the Z-axis tubular coil is sandwiched between the X-axis sheet coil and the Y-axis sheet coil). It is more preferable to place it in. For example, in the example of FIG. 15, the X-axis sheet coil 117X is arranged on the left side, the Z-axis cylindrical coil 119 is arranged in the center, and the Y-axis sheet coil 117Y is arranged on the right side. It is described as (117X, 119, 117Y). In the arrangement in which the Z-axis cylindrical coil 119 is arranged in the center, the arrangement in the order shown in FIG. 15 (117X, 119, 117Y) and the state shown in FIG. 15 are rotated by 90 [°] around the Z axis. There is a way of arranging the order of (117Y, 119, 117X). As shown in the example of FIG. 16, the arrangement of the order of the Z-axis cylindrical coils 119 arranged at the left end (119, 117X, 117Y) and, although not shown, (119, 117Y, 117X), and The Z-axis cylindrical coil 119 may be arranged in the order of (117X, 117Y, 119) and (117Y, 117X, 119) arranged at the right end portion.

The detonation side receiving antenna 11 has three types: a Z-axis tubular coil 119 (cylindrical coil), an X-axis sheet coil 117X (sheet coil), and a Y-axis sheet coil 117Y (sheet coil). Instead of being composed of a coil and a tubular magnetic material, it may be composed of at least one coil of a tubular coil or a sheet-shaped coil and a tubular magnetic material. In that case, for the charge position P2c shown in FIG. 5, as shown in the example of FIG. 17, the Z-axis cylindrical coil 119, the X-axis sheet coil 117X, the base cylinder 114, and the tubular magnetic material 115 The detonation side receiving antenna 11C may be configured with the above (however, the base cylinder 114 may be omitted). Further, in the example of FIG. 5, for example, with respect to the charging position P2b, as shown in the example of FIG. 11A may be configured (however, the base cylinder 114 may be omitted). Further, for the charge position P1b shown in FIG. 5, as shown in the example of FIG. 19, the Y-axis sheet-shaped coil 117Y, the base cylinder 114, and the tubular magnetic body 115 constitute the detonation side receiving antenna 11B. However, the base cylinder 114 may be omitted). That is, depending on the position of the charge hole, the antenna is configured with the direction in which the (most) magnetic field component is large at that position as the axis. In this case, it is more preferable to align the winding axis of the conductive wire of the antenna with the direction of the magnetic field at that position, not limited to the X-axis, Y-axis, and Z-axis.

In addition, with respect to the example shown in FIGS. 18 and 19, the detonation side receiving antenna may be configured by the X-axis sheet coil 117X, the base cylinder 114, and the tubular magnetic material 115 (however, the base cylinder). 114 may be omitted). Further, with respect to the example shown in FIG. 17, the Z-axis tubular coil 119 and the X-axis sheet coil 117X may be changed to the Z-axis tubular coil 119 and the Y-axis sheet coil 117Y. , X-axis sheet-shaped coil 117X and Y-axis sheet-shaped coil 117Y may be changed. In this way, different detonation-side receiving antennas are selected for each position of the charge hole on the face surface, and the energy for driving the electronic circuit and the energy for ignition are more efficiently used in each charge hole drilled on the face surface. It is possible to realize a detonating side receiving antenna that can receive the energy and receive the radio control signal.

Next, the structure of the detonating side transmitting antenna 18 will be described with reference to FIG. The detonation side transmission antenna 18 has a response frequency set to 100 [MHz] or more and 1 [GHz] or less, does not need to transfer the driving energy and the ignition energy of the electronic circuit, and transmits a response signal to the detonation operating device. Just need it. Therefore, the size may be about several [cm], and no magnetic material is required. As shown in FIG. 20, the detonating side transmitting antenna 18 includes a base portion 181 which is a sheet or plate-like member of an insulator, a conductor antenna portion 182 printed on the surface of the base portion 181 and the like, and an antenna portion 182. It is composed of a conductive wire 111 or the like that connects the control unit and the control unit. As shown in the example of FIG. 28, when the electronic circuit 120 and the detonating side transmitting antenna 18 are integrated, the antenna portion 182 is printed on the electronic circuit board, and the antenna portion 182 is connected to the wiring pattern on the electronic circuit board. It may be connected to the electronic circuit 120 at 153. The conductive wire 111 (see FIG. 20) connecting the antenna portion 182 and the electronic circuit 120 is replaced with the wiring pattern 153 in the example of FIG. 28. In the example of FIG. 20, the shape of the antenna portion 182 is shown as a pair of U-shaped portions facing each other, but the shape is not particularly limited. Further, although FIG. 20 shows an example in which the antenna portion 182 is provided on the front side surface and the back side surface of the base portion 181. However, the antenna portion 182 may be provided on at least one of the front side and the back side.

In the following description of each coil, the axis of the tubular magnetic material will be described as the Z axis, the axis orthogonal to the Z axis will be described as the X axis, and the axis orthogonal to both the Z axis and the X axis will be described as the Y axis. FIG. 21 shows an example of the appearance of the Z-axis cylindrical coil 119. The Z-axis cylindrical coil 119 is a cylindrical coil formed in a tubular shape by winding a conductive wire 111 around the Z-axis. Although FIG. 21 shows an example in which the conductive wire 111 is wound around the tubular body 112 to form a tubular coil, the conductive wire 111 may be wound around the tubular body 112 to form a tubular coil without providing the tubular body 112. Further, from the state of the exploded perspective view of FIG. 18, the Z-axis cylindrical coil 119 (corresponding to the tubular coil) is coaxial with the thin-walled cylindrical magnetic body 115 (in this case, coaxial with the Z-axis). The detonation side receiving antenna 11A (Z-axis tubular antenna (Z-axis receiving antenna)) can be configured by providing the tubular magnetic material 115 on the outer peripheral surface of the tubular magnetic body 115 and forming the whole into a cylindrical shape. can.

FIG. 22 shows an example of the appearance of the sheet-shaped coil 117X for the X-axis. As shown in FIG. 24, the sheet-shaped coil 117X for the X-axis has a sheet-shaped coil in which a conductive wire 111 is wound around each of the parallel virtual axes JNA and JNB and is orthogonal to each of the virtual axes JNA and JNB. As shown in FIG. 22, it is a sheet-shaped coil formed in a cylindrical shape so that the virtual axes JNA and JNB are coaxial with each other. As shown in FIG. 22, in the X-axis sheet coil 117X, the virtual axes JNA and JNB (see FIG. 24) are curved so as to be coaxial, and the coaxial virtual axes JNA and JNB are parallel to the X axis. It is arranged so as to be. That is, the sheet-shaped coil 117X for the X-axis is a sheet-shaped coil in which the conductive wire 111 is wound around the X-axis. As shown in FIG. 24, the conductive wire 111 may be wound around the sheet 113 to form a sheet-shaped coil, or the conductive wire 111 may be wound around the sheet 113 to form a sheet-shaped coil without providing the sheet 113. May be good. Further, in the exploded perspective view shown in FIG. 19, the Y-axis sheet-shaped coil 117Y is replaced with the X-axis sheet-shaped coil 117X, and from the state of the exploded perspective view, it is curved along the outer peripheral surface of the tubular magnetic material 115. The X-axis sheet-shaped coil (corresponding to the sheet-shaped coil) is provided on the outer peripheral surface of the thin-walled tubular magnetic material 115 to form the entire tubular shape, so that the detonation side receiving antenna (X) is formed. A shaft sheet-shaped antenna (X-axis receiving antenna) can be configured. At this time, in the sheet-shaped coil for the X-axis, a conductive wire is wound around an axis (in this case, the X-axis) orthogonal to the axis (Z-axis) of the tubular magnetic body 115. As an example of the sheet-shaped coil 116 in which the conductive wire 111 is wound around each of the virtual axes JNA and JNB, the conductive wire 111 may be wound as shown in FIGS. 25 and 26.

FIG. 23 shows an example of the appearance of the Y-axis sheet coil 117Y. As shown in FIG. 24, the Y-axis sheet-shaped coil 117Y has a sheet-shaped coil in which a conductive wire 111 is wound around each of the parallel virtual axes JNA and JNB and is orthogonal to each of the virtual axes JNA and JNB. As shown in FIG. 23, it is a sheet-shaped coil formed in a cylindrical shape so that the virtual axes JNA and JNB are coaxial with each other. As shown in FIG. 23, the Y-axis sheet coil 117Y is curved so that the virtual axes JNA and JNB (see FIG. 24) are coaxial, and the coaxial virtual axes JNA and JNB are parallel to the Y axis. It is arranged so as to be. That is, the sheet-shaped coil 117Y for the Y-axis is a sheet-shaped coil in which the conductive wire 111 is wound around the Y-axis. As shown in FIG. 24, the conductive wire 111 may be wound around the sheet 113 to form a sheet-like coil, or the conductive wire 111 may be wound around the sheet 113 to form a sheet-like coil without providing the sheet 113. May be good. Further, in the exploded perspective view shown in FIG. 19, the Y-axis sheet-shaped coil (corresponding to the sheet-shaped coil) curved along the outer peripheral surface of the tubular magnetic material 115 from the state of the exploded perspective view is thinned. The detonation side receiving antenna (Y-axis sheet-shaped antenna (Y-axis receiving antenna)) can be configured by providing it on the outer peripheral surface of the tubular magnetic body 115 and forming the whole into a cylindrical shape. can. At this time, in the sheet-shaped coil for the Y-axis, a conductive wire is wound around an axis (in this case, the Y-axis) orthogonal to the axis (Z-axis) of the tubular magnetic material 115. As an example of the sheet-shaped coil 116 in which the conductive wire 111 is wound around each of the virtual axes JNA and JNB, the conductive wire 111 may be wound as shown in FIGS. 25 and 26.

Therefore, the sheet-shaped coil 117X for the Y-axis is the one in which the sheet-shaped coil 117X for the X-axis is swiveled by 90 [°] around the Z-axis. When each of the Z-axis tubular coil 119, the X-axis sheet coil 117X, and the Y-axis sheet coil 117Y is provided on the outer peripheral surface of the tubular magnetic material 115, the tubular magnetic material 115 It is possible to receive the driving energy, the ignition energy, and the control signal of the electronic circuit more efficiently than the case where the inner peripheral surface is provided. Further, as shown in FIGS. 22 and 23, in the description of the present embodiment, the winding of the conductive wire 111 in the sheet-shaped coil 117X for the X-axis and the sheet-shaped coil 117Y for the Y-axis is wound in a rectangular shape. However, the shape of the winding is not limited to a rectangular shape, and may be wound into a spiral shape or various polygonal shapes. Further, it may be wound so that various shapes are mixed. Further, the Z-axis cylindrical coil, the X-axis sheet-shaped coil, and the Y-axis sheet-shaped coil may be created by the operator manually winding the conductive wire 111 a predetermined number of times.

● [Circuit in the control unit 12 and the detonation unit 14 of the wireless detonator 10 (FIG. 27)]
Next, using the circuit block diagram shown in FIG. 27, the circuits (circuits of the electronic circuit 120 and the detonator 14) in the control unit 12 and the detonator 14 of the wireless detonator 10 will be described. FIG. 27 shows each circuit (block diagram) of the electronic circuit 120 and the detonation unit 14 housed in the control unit 12, including the detonation side receiving antenna 11 and the detonation side transmitting antenna 18 shown in FIG.

The X-axis sheet-shaped coil 117X is connected to the 3-axis synthesis circuit 124 via a tuning circuit 121 composed of a variable capacitor or the like. Similarly, the Z-axis cylindrical coil 119 is connected to the 3-axis synthesis circuit 124 via a tuning circuit 122 composed of a variable capacitor or the like. Similarly, the Y-axis sheet coil 117Y is connected to the 3-axis synthesis circuit 124 via a tuning circuit 123 composed of a variable capacitor or the like. In this way, in each of the X-axis sheet coil 117X, the Z-axis cylindrical coil 119, and the Y-axis sheet coil 117Y, the conductive wire 111 is connected to each of the tuning circuits 121, 122, 123. ing. Each of the tuning circuits 121, 122, and 123 is connected to the 3-axis synthesis circuit 124.

The detonating side transmitting antenna 18 is composed of an antenna portion 182 on which a conductor is printed or the like. The antenna portion 182 is connected to the transmission circuit 134 by a wiring pattern 153 (or a conductive wire). When the CPU 131 transmits a response signal, the response signal from the CPU 131 is transmitted from the detonation side transmission antenna 18 via the wiring pattern 153 (or the conductive wire) via the modulation circuit 133 and the transmission circuit 134.

The electronic circuit 120 includes tuning circuits 121, 122, 123, 3-axis synthesis circuit 124, CPU 131, detection / demodulation circuit 125, regulator 128, modulation circuit 133, transmission circuit 134, ID storage device 132, and electronic circuit drive power storage device 127. It is composed of an ignition switch circuit 138, a rectifying circuit 126, and the like. Each of the tuning circuits 121, 122, and 123 is a variable capacitor for adjusting the resonance frequency of the corresponding sheet-shaped coil 117X for X-axis, tubular coil 119 for Z-axis, and sheet-shaped coil 117Y for Y-axis. It is composed of etc.

The 3-axis synthesis circuit 124 includes an X-axis sheet-shaped antenna (X-axis sheet-shaped coil 117X constituting the X-axis receiving antenna) and a Y-axis sheet-shaped antenna (Y-axis sheet constituting the Y-axis receiving antenna).

The energy and control signals are combined and output to the path 151 and the path 152. The path 151 is a route for taking in the received control signal, and the path 152 is a route for rectifying, storing, and converting the received energy into a constant voltage. Then, the radio control signal received via the path 151 and the detection / demodulation circuit 125 is taken into the CPU 131, and the driving energy (and ignition) of the electronic circuit via the path 152 and the regulator 128 (constant voltage circuit) is taken. The energy) is used as a power source for an electronic circuit such as a CPU, and is stored in a power storage device 127 for driving the electronic circuit.

The ID storage device 132 stores identification information unique to the wireless detonator 10. Upon receiving the ID request signal (control signal), the CPU 131 transmits a response signal including the identification information read from the ID storage device 132. Although the example in which the ID storage device 132 is configured separately from the CPU 131 is shown here, the present invention is not limited to this, and the ID storage device 132 may be built in the CPU 131.

When the CPU 131 receives a command corresponding to the ignition instruction (or when a predetermined ignition delay time has elapsed after receiving the command corresponding to the ignition instruction), the CPU 131 uses the control signal 156 to send the ignition switch circuit 138. Is controlled from an open state to a short-circuited state, and the energy stored in the electronic circuit driving power storage device 127 (electronic circuit driving energy and ignition energy) is output to the ignition circuit 141 to execute detonation. Further, the CPU 131 has a storage means, and the wireless igniter side program is stored in the storage means.

In the ignition circuit 141, when the ignition switch circuit 138 is short-circuited, electric power (ignition energy) is supplied from the electronic circuit drive power storage device 127 to ignite the ignition ball 142. Then, when the squib 142 is ignited, the detonator 143 and the auxiliary charge 144 are ignited, and the detonator portion 14 is ignited. Then, when the detonation unit 14 is ignited, the parent die 36A shown in FIG. 2 is detonated.

● [Example of integrating the electronic circuit 120 and the detonating side transmitting antenna 18 (FIG. 28)]
As described above, since the detonating side transmitting antenna 18 may have an antenna portion of a conductor of about several [cm] printed on an insulator or the like, the detonating side transmitting can be performed on the electronic circuit board constituting the electronic circuit 120. It is possible to form the antenna 18. Therefore, as shown in the example of FIG. 28, the antenna portion 182 can be printed or the like on a part of the plate-shaped (or sheet-shaped) electronic circuit board 129 of the insulator. Therefore, the electronic circuit 120 and the detonating side transmitting antenna 18 can be integrated on the electronic circuit board 129, and the miniaturization and ease of assembly can be further improved.

● [Effects of the present invention, etc.]
In the wireless crushing system 1 described in the present embodiment, the operating frequency is 100 [kHz] or more and 500 [kHz] or less. The detonating side receiving antenna 11 (reception-only antenna) of the wireless detonating lightning tube can efficiently receive the driving energy and the ignition energy of the electronic circuit, and can efficiently receive the wireless control signal. The number of windings of the detonation operating device side transmitting antenna 60 (antenna dedicated to transmission) shown in 1 can be set to about once or several times. Then, by supplying the current of the operation frequency to the transmission antenna 60 on the detonation operating device side, the control unit 12 (electronic circuit 120) of the wireless detonator detonator 10 is supplied with electricity and the ignition energy is stored. The electric power supplied to the detonation operation device side transmitting antenna 60 for power supply and storage to the control unit 12 can be performed with a relatively small electric power of about several tens [W] to several 100 [W]. Further, the radio detonator is controlled by the control signal superimposed on the current.

Further, a receiving antenna 65 (reception-only antenna) on the detonation operating device side is provided, and the frequency of the signal responding from the wireless detonator 10 is set to 100 [MHz] or more and 1 [GHz] or less. As a result, the detonator-side transmitting antenna 18 (transmission-only antenna) of the wireless detonator can be made smaller, and the response signal can be transmitted more efficiently, and the reach of the longer response signal (the reach of the longer response signal). For example, about 50 [m]) can be realized.

Further, the detonation side receiving antenna 11 described in the present embodiment is a Z-axis cylinder capable of efficiently receiving the driving energy of the electronic circuit, the ignition energy, and the wireless control signal from the magnetic field in the Z-axis direction. A Z-axis tubular antenna (Z-axis receiving antenna) made of a cylindrical coil 119 and a tubular magnetic material, and efficiently receive electronic circuit drive energy, ignition energy, and radio control signals from a magnetic field in the X-axis direction. A sheet-shaped coil 117X for the X-axis, a sheet-shaped antenna for the X-axis (reception antenna for the X-axis) made of a tubular magnetic material, and energy for driving and ignition of an electronic circuit efficiently from a magnetic field in the Y-axis direction. It has a Y-axis sheet-shaped coil 117Y capable of receiving a radio control signal, and a Y-axis sheet-shaped antenna (Y-axis receiving antenna) made of a tubular magnetic material. Therefore, the charging hole 40 drilled at any position on the face surface 41 shown in FIG. 1 can more efficiently receive the driving energy and the ignition energy of the electronic circuit and control the radio. Can receive signals. Further, as shown in FIG. 2, by inserting the explosive into the cylindrical detonation side receiving antenna 11, it becomes possible to load a larger amount of the explosive into the charge hole, and the detonation efficiency is improved. Can be done.

Further, since the detonating side transmitting antenna is provided at a position protruding to the outside of the detonating side receiving antenna 11 and at a position not in contact with the detonating side receiving antenna, the wireless detonating lightning tube and the detonating side transmitting antenna are integrated, so that the conductive wire can be used. Compared to the case of having a separate detonation side transmitting antenna connected by can do.

● [Addition of transmission auxiliary antenna 19 that supplements transmission from the detonation side transmission antenna 18 (FIGS. 29 to 33)]
As shown in FIG. 2, the radio detonator 10 is loaded at the innermost part of the charge hole 40. Therefore, the detonation side transmission antenna 18 that transmits the response signal from the wireless detonator detonator 10 is also located deep in the charge hole 40. Therefore, depending on the type of bedrock around the charge hole, the transmission signal from the detonation side transmitting antenna 18 may be blocked, and the transmission signal may not be efficiently transmitted toward the detonation operation device side receiving antenna 65. Can be considered. Therefore, by adding a transmission auxiliary antenna 19 that supplements the transmission from the detonation side transmission antenna 18 to the wireless detonator, the transmission signal can be efficiently transmitted to the detonation operation device side reception antenna.

FIG. 29 shows an example of the appearance of the wireless detonator 10B in which the transmission auxiliary antenna 19 is added to the wireless detonator shown in the cross-sectional view of FIG. The wireless detonator having the electronic circuit 120, the detonation side receiving antenna 11, the detonating side transmitting antenna 18, and the detonating unit 14 is housed in a protective case 165 and a control case 162, which are tubular cases, and the wireless detonator tube. It forms 10B. The shapes of the protective case 165 and the control case 162 are not limited to a cylindrical shape, and may be a cylindrical shape. The size of the control case 162 is a size that can protect and accommodate the electronic circuit 120 having the detonating side transmitting antenna 18, and the diameter orthogonal to the antenna axis J11 is loaded in the charging hole 40 as shown in FIG. It is set to a possible diameter. Further, the length of the control case 162 along the antenna shaft J11 is set to a length that can accommodate the electronic circuit 120 without waste. The size of the protective case 165 is a size that can protect and accommodate the detonating side receiving antenna 11 and the detonating portion 14, and the diameter orthogonal to the antenna axis J11 is a diameter that can accommodate the detonating side receiving antenna 11 and the figure. As shown in 30, the diameter is set so that a part of the parent die 36A can be accommodated and the diameter can be loaded in the charging hole 40. Further, the length of the protective case 165 along the antenna shaft J11 is long enough to accommodate the detonating receiving antenna 11 and the detonating portion 14 without waste, and can accommodate at least a part of the parent die 36A as shown in FIG. The length is set. The diameter of the control case 162 (diameter orthogonal to the antenna axis J11) and the diameter of the protective case 165 (diameter orthogonal to the antenna axis J11) may be set so that one diameter is larger than the other diameter. And may be the same. Further, the length of the control case 162 (the length along the antenna shaft J11) and the length of the protective case 165 (the length along the antenna shaft J11) are set so that one length is longer than the other length. It may be the same or it may be the same. Then, the transmission auxiliary antenna 19 having a predetermined length (length set according to the length of the charge hole 40 shown in FIG. 30) is not connected to the detonator side transmission antenna 18 (detonation side transmission antenna 18). It is attached to the radio detonator 10B. The transmission auxiliary antenna 19 has a predetermined length of the guide portion 191 formed of a conductor such as metal or carbon and the lead portion 192 formed of a conductor such as metal or carbon, and has a predetermined length at the joint portion 193. The guide portion 191 and the lead portion 192 are joined to each other. The "predetermined length" is opposite to the side attached to the other end of the transmission auxiliary antenna 19 (the side attached to the protective case or the control case) when the radio detonator 10B is loaded into the charging hole 40 as shown in FIG. Side) is set to a length longer than possible to reach the opening 45 of the charging hole 40.

The induction unit 191 is on one end side of the transmission auxiliary antenna 19, is not connected to the detonation side transmission antenna 18, and is attached to at least one of the outer side or the inner side in a part of the protective case 165 and the control case 162. ing. Although the induction unit 191 (transmission auxiliary antenna 19) and the detonation side transmission antenna 18 are not connected, the distance of the shortest portion from the guidance unit 191 to the detonation side transmission antenna 18 is preferably as short as possible. The example of FIG. 29 shows an example in which the guide portion 191 is attached to the outside of a part of the protective case 165, from one end to the other end of the protective case 165 so as to be substantially parallel to the antenna axis J11. , An example in which the guide portion 191 is attached is shown. In this case, if the guide portion 191 is made of a copper foil or an aluminum foil having a predetermined thickness, it can be easily attached to the protective case 165 with an adhesive tape or the like. The induction unit 191 receives the transmission signal wirelessly transmitted from the detonation side transmission antenna 18 to the detonation side transmission antenna 18 in a non-contact manner, and propagates the received transmission signal to the lead unit 192. Note that FIG. 29 shows an example in which the guide portion 191 is set to the length from one end to the other end of the protective case 165, but the length in the axial direction parallel to the antenna shaft J11 in the guide portion 191 is particularly high. Not limited. Further, the width of the induction unit 191 in the circumferential direction around the antenna axis J11 is set to about 10 [mm] or less so as not to cover the detonating side receiving antenna 11.

The lead portion 192 is on the other end side of the transmission auxiliary antenna 19, is not connected to the detonation side transmission antenna 18, and is extended so as to be separated from the protective case 165 and the control case 162. In the example of FIG. 29, the lead portion 192 having a conductive wire coated with an insulator is joined to the guide portion 191 by soldering or the like at the joint portion 193, and extends so as to be separated from the protective case 165 and the control case 162. It shows an example of being soldered. The lead unit 192 transmits the transmission signal propagated from the induction unit 191 from the hanging portion 194 from the opening 45 of the charge hole 40 in FIG. 30 toward the detonator side receiving antenna 65. In this case, the hanging portion 194 becomes a substantial transmitting antenna. The hanging length L19 of the hanging portion 194 in FIG. 30 is preferably a length of 1/4 or more of the wavelength of the transmission signal. For example, when the response frequency is 315 [MHz], the wavelength λ = 3.00 × ¹⁰⁸ [m / s] / 315 [MHz] = about 1 [m]. It is preferably 25 [cm] or more.

FIG. 30 shows a state in which the wireless detonator is the wireless detonator 10B shown in FIG. 29, as opposed to FIG. 2, which shows a state in which the explosive unit using the wireless detonator is loaded in the charging hole 40. .. The transmission auxiliary antenna 19 is drawn out from the opening 45 of the charge hole 40 and has a hanging portion 194, and the hanging length L19 is preferably 1/4 or more of the wavelength of the transmission signal. Further, by attaching the display device 72 by using the transmission auxiliary antenna 19 instead of the cable 71 in FIG. 2, the cable 71 can be omitted. In the step of loading the explosive, as shown in FIG. 30, the parent die 36A, which is the explosive to which the wireless detonator 10B is attached, and the additional die 36B, which is the explosive to which the wireless detonator 10B is not attached, are used (that is, the explosive). The unit 20 is loaded into the charge hole 40, and the other end side (the side of the lead portion 192) of the transmission auxiliary antenna 19 is loaded into the charge hole 40 so as to hang down from the opening 45 of the charge hole 40.

31 to 33 show an example in which the attachment point of the guide portion 191 of the transmission auxiliary antenna 19 is changed in FIG. 29. FIG. 31 shows an example in which the guide portion 191 is attached (pasted) from one end to the other end of the protective case 165 and from one end to the other end of the control case 162 so as to be substantially parallel to the antenna shaft J11. Is shown. Note that FIG. 31 shows an example in which the guide portion 191 is set to a length from one end to the other end of the protective case 165 and from one end to the other end of the control case 162, but the antenna shaft in the guide portion 191 is shown. The length in the axial direction parallel to J11 is not particularly limited. Further, the width of the induction unit 191 in the circumferential direction around the antenna axis J11 is set to about 10 [mm] or less so as not to cover the detonating side receiving antenna 11.

Further, FIG. 32 shows an example in which the guide portion 191 is attached (pasted) from one end to the other end of the control case 162 so as to be substantially parallel to the antenna shaft J11. Note that FIG. 32 shows an example in which the guidance unit 191 is set to a length from one end to the other end of the control case 162, but the length in the axial direction parallel to the antenna shaft J11 in the guidance unit 191 is set. Not particularly limited. Further, the width of the guide portion 191 in the circumferential direction around the antenna axis J11 is not particularly limited.

Further, FIG. 33 shows an example in which the guide portion 191 is wound and attached around the control case 162 so as to orbit the antenna shaft J11. Note that FIG. 33 shows an example in which the guide unit 191 is continuously wound around the control case 162, but the length of the guide unit 191 around the antenna axis J11 in the circumferential direction is not particularly limited. Further, the width of the guide portion 191 in the axial direction parallel to the antenna axis J11 is not particularly limited.

The guide portion 191 may be attached to at least one of the outer side and the inner side in a part of the protective case 165 and the control case 162. For example, FIG. 29 shows an example in which the guide portion 191 is attached to the outside of a part of the protective case 165, but the guide portion 191 may be attached to the inside of the protective case 165, or the guide portion 191 may be attached. Some may be attached to the inside of the protective case and the rest to the outside of the protective case. Further, the guide portion 191 and the lead portion 192 may be formed by one continuous conductive wire (in this case, the joint portion 193 is omitted). Further, since the transmission auxiliary antenna 19 is not connected to the detonation side transmission antenna 18, static electricity, leakage current (from surrounding high-voltage electric wires, etc.) and stray voltage (flowing in the ground for some reason) are found in the charge hole 40. Even if there is a current and the transmission auxiliary antenna 19 picks it up, it can be prevented from being transmitted to the electronic circuit 120 via the detonation side transmission antenna 18. As described above, various examples can be considered as examples of the induction unit 191. As an example of a preferable form of the induction unit 191, the induction unit 191 shown in the example of FIG. 29 has a diameter of about 0.4 [mm]. A guide portion 191 formed by attaching the lead wire (copper wire) of the above to the surface of the protective case 165 with an adhesive or the like can be considered.

● [Configuration of detonation operation device 50 (wireless ignition operation device) (Fig. 34)]
Next, the configuration of the detonation operating device 50 will be described with reference to the block diagram shown in FIG. 34. The detonation operation device 50 includes a CPU 501, an input device 502, a storage device 503, a transmission circuit 504, a reception circuit 505, a display device 506, a switching circuit 507, and the like.

The input device 502 is, for example, a keyboard, a mouse, or the like, and an instruction from an operator is input. Further, the display device 506 is, for example, a liquid crystal monitor, and displays the operating state of the detonation operating device 50 and instructions from the operator. The display device 506 may be used as a touch monitor.

The storage device 503 stores a program on the side of the wireless ignition operation device. The CPU 501 executes the "processing of the detonation operating device 50 (wireless ignition operating device)" described later by executing the program on the wireless ignition operating device side read from the storage device 503. The details of the control signal transmitting means 501A, the response signal receiving means 501B, the ignition tool state determining means 501C, the delay time rewriting requesting means 501D, the ignition transmission permitting means 501E, and the ignition request transmitting means 501F in the CPU 501 will be described later.

The transmission circuit 504 wirelessly transmits the control signal input from the CPU 501 from the detonation operation device side transmission antenna 60 via the blasting bus 62, the relay device 51, and the auxiliary bus 61. In the receiving circuit 505, the response signal wirelessly transmitted from the wireless detonator is input via the detonator side receiving antenna 65, the detonation operating device side receiving antenna cable 66, the relay device 51, and the burst bus 62, and is input. The response signal is output to the CPU 501. Further, the switching circuit 507 switches the transmission / reception route in the relay device 51 based on the switching signal from the CPU 501.

● [Wireless crushing process (Fig. 35)]
Next, the procedure of the worker's wireless crushing process at the crushing site will be described with reference to the flowchart of FIG. As shown in the wireless crushing process of FIG. 35, the operator can perform the charging hole drilling process K10, the loading process K20, the ignition operation machine side transmission antenna installation process K30, the ignition operation machine side reception antenna installation process K40, and the wireless ignition. The operation machine installation process K50 and the crushing process K60 are performed in this order.

In the charge hole drilling step K10, the operator drills a plurality of charge holes in the crushed portion (for example, the face surface 41 shown in FIG. 1). The position of each charge hole and the number of charge holes in the crushed portion are appropriately set according to the state of the crushed portion and the like.

In the loading step K20, as shown in FIG. 2, the operator loads the parent die 36A and the expansion die 36B to which the wireless detonator tube 10 is attached into each of the drilled charge holes, and displays them outside the charge holes. Pull out the device 72. It should be noted that each wireless detonator 10 stores ignition tool identification information including at least one of an ID or a serial number that can identify each wireless detonator, and the ignition tool identification information is described on the display device 72. ing. The operator makes a note in advance which charge hole is loaded with the radio detonator of which ignition device identification number. For example, as in the setting information shown in FIG. 42, the ignition tool identification information may be stored in association with the charge hole information indicating the position of each charge hole. As for the method of storing the ignition device identification information in association with the charge hole information, any method may be used.

In the ignition operation device side transmission antenna installation step K30, as shown in FIG. 1, the operator stretches the detonation operation device side transmission antenna 60 in a loop shape at a position separated by a distance L1 from the crushed portion. Then, the auxiliary bus 61, the relay device 51, and the blasting bus 62 are connected to the transmission antenna 60 on the detonation operation device side.

In the ignition operation device side receiving antenna installation step K40, as shown in FIG. 1, the operator installs the detonation operation device side receiving antenna 65 at a position separated by a distance L2 from the crushing point. Then, the receiving antenna 65 on the detonation operating device side and the relay device 51 are connected by the receiving antenna cable 66 on the detonating operating device side.

In the wireless ignition operation device installation step K50, as shown in FIG. 1, the operator installs the detonation operation machine 50 in a safe place sufficiently away from the crushing point, and connects the blasting bus 62 to the detonation operation machine 50. .. The operator prepares in advance a shield box body surrounded by an electromagnetic shield member that blocks wireless electronic circuit drive energy, ignition energy, control signal, and response signal. The inner surface of the shield box is an insulator without exposing the conductor. Then, the worker brought the surplus radio detonator to the crushing site, but if there was a surplus radio detonator that was not loaded in the charge hole, the surplus radio detonator was used as the detonator 50 (wireless ignition detonator). By blocking the radio waves radiated from, the electronic circuit is prevented from starting, and it is safely stored inside the shield box. This prevents the surplus wireless detonator detonator 10 (wireless ignition tool) from being activated by the radiated radio waves from the detonation operating device 50 (wireless ignition operating device), and crushing work and the surplus wireless detonator detonator 10 (wireless). Ignition equipment) can be stored at the same time and safely.

In the crushing step K60, the operator operates the detonation operating device 50 to ignite the radio detonator, ignite the explosives (parent die and increased die), and crush the crushed portion. The details of the processing procedure of the detonation operating device 50 and the processing procedure of the wireless detonator detonator 10 at this time will be described below.

● [Processing procedure of detonation operation machine 50 (wireless ignition operation machine) (FIG. 36)]
Next, an example of the processing procedure of the detonation operating device 50 (wireless ignition operating device) will be described with reference to the flowchart shown in FIG. The detonation operating device 50 (wireless ignition operating device) executes a wireless crushing method based on the processing of the flowchart shown in FIG. 36 by executing the wireless ignition operating device side program stored in the storage device 503. .. When the detonation operation machine 50 is activated by the operator, the process proceeds to step S10 shown in FIG. 36.

In step S10, the detonation operation machine 50 displays the process and the like on the display device 506, and proceeds to step S20. For example, as shown in FIG. 46, the display device 506 displays a process display unit 506A, a crushed portion display unit 506B, and a setting information display unit 506C. For example, on the process display unit 506A, each process of "supplying energy to the wireless ignition tool", "charge confirmation", "delay time rewriting", "ignition standby", "ignition count start", and "interruption" is displayed. To. For example, the crushed portion information Z20 shown in FIG. 41 is displayed on the crushed portion display unit 506B, and the setting information Z10 shown in FIG. 42, for example, is displayed on the setting information display unit 506C.

[Crushed location information Z20 (FIG. 41) and setting information Z10 (FIG. 42)]
The crushed location information Z20 shown in FIG. 41 includes the entire outline of the crushed location at the crushing site, the position of each charge hole, the charge hole identification information for identifying the charge hole, and the crushed location. Area A1 within the first distance from the central part, area A2 within the second distance from the first distance, area A3 within the third distance from the second distance, area A4 within the fourth distance from the third distance Etc. are associated with each other. For example, the setting information Z10 shown in FIG. 42 is displayed on the setting information display unit 506C. In the setting information Z10 shown in FIG. 42, an area (an area corresponding to the distance from the central portion of the crushed portion), an ignition delay time, an ignition tool identification information, and the like are associated with the charge hole identification information. The ignition delay time is set so that the longer the distance from the central portion of the crushed portion to the charging hole, the longer the ignition delay time. That is, the ignition delay time of the area A1 <the ignition delay time of the area A2 <the ignition delay time of the area A3 <the ignition delay time of the area A4 is set.

In step S20, the detonation operating device 50 wirelessly transmits the driving energy and the ignition energy of the electronic circuit 120 of the wireless detonator detonator 10 via the detonation operating device side transmitting antenna 60, and proceeds to the process to step S110. .. The driving energy and the ignition energy are continuously transmitted until the crushing process is completed or the interruption (the interruption will be described later). For example, the detonation operation machine 50 is used for driving energy and ignition when the "supplying energy to the wireless ignition tool" of the process display unit 506A shown in FIG. 46 displayed on the display device is operated (pressed) by the operator. Pass energy wirelessly. The driving energy, the ignition energy, and the control signal described later are transmitted from the detonation operating device 50 at an operating frequency of 100 [kHz] or more and 500 [kHz] or less, and are transmitted at, for example, 200 [kHz].

In step S110, the detonation operation device 50 blinks "charge confirmation" and "interruption" in the process display unit 506A shown in FIG. 46 displayed on the display device, and causes "charge confirmation (instruction)" or "interruption". (Instruction) ”is displayed to remind the operator to input, and the process proceeds to step S115.

In step S115, the detonation operation machine 50 determines whether or not the "interruption instruction" has been input, and if the "interruption instruction" is input (Yes), the process proceeds to step A and the "interruption instruction" is input. If not, the process proceeds to step S120.

When the process proceeds to step A, the detonation operation machine 50 proceeds to the process in step S525, and in step S525, the global ID, the interruption instruction (interruption command), and the dummy data (00) are stored in the control data. The process proceeds to step S530. In this case, the detonation operation machine 50 stores the global ID in the "ID" of the control data, stores the interruption instruction (suspension command) in the "command", and stores the dummy data (00) in the "data".

[Control data (control signal) transmitted from the detonation actuator 50 (FIGS. 38 and 39)]
Here, the control data (control signal) transmitted from the detonation operation device 50 will be described in detail. An example of the data structure of the control data (control signal) transmitted from the detonation operation device 50 is as shown in FIG. 38. The control data (control signal) is configured as, for example, a 4-byte data group, the first byte is "ID", the second byte is "command", the third byte is "data", and the fourth byte is "checksum". (CS) ”is stored.

As shown in the example of FIG. 39, the "ID" has an individual ID and a global ID, and when a command targeting a specific radio detonator is transmitted, the "ID" is "individual". ID (= ignition tool identification information) ”is stored and transmitted. When transmitting a command targeting all radio detonators instead of a specific one, the "global ID" (corresponding to global information) is stored in the "ID" and transmitted. As shown in the example of FIG. 39, the "command" includes an "interruption instruction", a "charge confirmation instruction", a "delay time rewriting instruction", an "ignition standby instruction", an "ignition count start instruction" and the like. Further, as shown in the example of FIG. 39, the “data” includes the “ignition delay time” or dummy data (00).

The checksum (CS) is one of the so-called error detection codes, and in this case, the value obtained by adding the respective values stored in the “ID”, “command”, and “data” is stored. The radio detonation tube 10 that has received the control data (control signal) has a value obtained by adding the values stored in the "ID", "command", and "data", a value stored in the "checksum", and a value stored in the "checksum". By comparing and confirming whether or not they match, it can be determined that the correct data has been received without changing the data value due to noise or the like. Instead of the checksum, a method using another error detection code (for example, a method using parity or CRC) may be used.

In step S530, the detonation operation machine 50 calculates the checksum (CS) by adding the respective values of the "global ID", the "interruption instruction", and the dummy data (00) stored in the control data, and controls the control. A control signal composed of data + CS is transmitted to the radio detonation tube 10 to end the process.

When the process proceeds to step S120, the detonation operation device 50 determines whether or not the "charge confirmation instruction" is input, and when the "charge confirmation instruction" is input (Yes), the process proceeds to step S125. If the "charge confirmation instruction" is not input (No), the process returns to step S110.

When the process proceeds to step S125, the detonation operation device 50 stores the global ID, the charge confirmation instruction (charge confirmation command), and the dummy data (00) in the control data, and proceeds to the process to step S130. In this case, the detonation operation machine 50 stores the global ID in the "ID" of the control data, stores the charge confirmation instruction (charge confirmation command) in the "command", and stores the dummy data (00) in the "data". ..

In step S130, the detonation operation machine 50 calculates the checksum (CS) by adding the respective values of the "global ID", the "charge confirmation instruction", and the dummy data (00) stored in the control data. The control signal configured by the control data + CS is transmitted to the radio detonation tube 10 and the process proceeds to step S135.

In step S135, the detonation operation machine 50 determines whether or not the "interruption instruction" has been input, and if the "interruption instruction" is input (Yes), the process proceeds to step A and the "interruption instruction" is input. If not, the process proceeds to step S140. Since the process of step A is as described above, the description thereof will be omitted.

When the process proceeds to step S140, the detonation operating device 50 determines whether or not a predetermined time has elapsed since the control signal of step S130 was transmitted, and if the predetermined time has elapsed (Yes), a time-out is set. After making a determination, the process proceeds to step S160, and if the predetermined time has not elapsed (No), the process proceeds to step S145.

When the process proceeds to step S145, the detonation operating device 50 determines whether or not the response signal from any of the wireless detonator detonators 10 has been received, and if the response signal is received (Yes), the process proceeds to step S150. If no response signal has been received (No), the process returns to step S135.

When the process proceeds to step S150, the detonation operation device 50 corresponds to the ID (ignition device identification information) included in the response signal and is in the charging state which is the "operating state" included in the response signal. Is stored, and the process proceeds to step S155. For example, as shown in FIG. 40, the charging state included in the response signal may be "charging completed" or "charging". For example, when the charging state included in the response signal is "charging completed", the detonation operating device 50 has "(response)" corresponding to the ID (igniter identification information) included in the response signal in the setting information. "Completed" is stored in the "Charging status" column (see FIG. 43). Further, when the charging state included in the response signal is "charging", the detonation operating device 50 has "(response)" corresponding to the ID (igniter identification information) included in the response signal in the setting information. "Charging" is stored in the "Charging state" column (see FIG. 43).

[Response data (response signal) transmitted from the radio detonator 10 (FIGS. 38 and 40)]
Here, the response data (response signal) transmitted from the wireless detonator 10 will be described in detail. An example of the data structure of the response data (response signal) transmitted from the wireless detonator 10 is as shown in FIG. 38. The response data (response signal) is configured as, for example, a 4-byte data group, the first byte is "ID", the second byte is "operating state", the third byte is "data", and the fourth byte is "check". "Sam (CS)" is stored.

As shown in the example of FIG. 40, the "ID" has its own ID, and the radio detonator stores the ignition device identification information stored by itself in the "ID" and transmits a response signal. do. Further, as shown in the example of FIG. 40, the "operating state" is the "operating state" for the "suspension instruction", "interruption completed" and "interruption abnormality", and the "charging confirmation instruction". "Charging completed" and "Charging", "Operating state" for "Delayed time rewriting instruction" "Delayed rewriting completed" and "Delayed rewriting failure", "Ignition standby instruction" for "Operating state" There are "Ignition waiting OK" and "Ignition waiting abnormality". Further, the "data" includes "ignition delay time" or dummy data (00) as shown in the example of FIG. 40.

The checksum (CS) is one of the so-called error detection codes, and in this case, a value obtained by adding the respective values stored in the “ID”, “operating state”, and “data” is stored. The detonation operation device 50 that has received the response data (response signal) has a value obtained by adding the values stored in the "ID", "operating state", and "data", and a value stored in the "checksum". By comparing and confirming whether or not they match, it can be determined that the correct data has been received without changing the data value due to noise or the like. Instead of the checksum, a method using another error detection code (for example, a method using parity or CRC) may be used.

In step S155, the detonation operation device 50 determines whether or not a response signal has been received from the all radio detonator tube 10 (all radio ignition tools), and if the response signal is received from the all radio detonator tube 10 (Yes). The process proceeds to step S160, and if there is a radio detonator 10 that has not received the response signal (No), the process returns to step S135. For example, the detonation operation device 50 can easily determine whether or not a response signal has been received from the all wireless detonator detonator 10 based on the setting information stored in "charging" and "completed" in step S150. can.

When the process proceeds to step S160, the detonation operating device 50 determines whether or not the charging states of all the wireless detonators 10 are all OK, and when all the charging states of all the wireless detonators are OK ( Yes) proceeds to step S210, and if even one of the charging states is not OK or if there is a wireless detonator that has not transmitted a response signal (No), the process proceeds to step B. For example, the detonation operation device 50 determines that all the charging states of all the wireless detonators are OK when the "(response) charging state" column in the setting information shown in FIG. 43 is all "completed". The process proceeds to step S210, and if not, the process proceeds to step B.

When the process is advanced to step B, the detonation operation machine 50 advances the process to step S510, and in step S510, for example, blinking "interruption" in the process display unit 506A shown in FIG. 46 displayed on the display device. Then, a display prompting the worker to input the "interruption instruction" is displayed, and the process proceeds to step S515.

In step S515, the detonation operation machine 50 determines whether or not the "interruption instruction" has been input, and if the "interruption instruction" is input (Yes), the process proceeds to step S525 and the "interruption instruction" is input. If not, the process returns to step S510. The processing of steps S525 and S530 is as described above.

When the process proceeds to step S210, the detonation operation machine 50 blinks the "delay time rewriting" and the "interruption" in the process display unit 506A shown in FIG. 46 displayed on the display device, for example, to blink the "delay time". A display is displayed to remind the operator to input "rewrite (instruction)" or "interruption (instruction)", and the process proceeds to step S215.

In step S215, the detonation operation machine 50 determines whether or not the "interruption instruction" has been input, and if the "interruption instruction" is input (Yes), the process proceeds to step A and the "interruption instruction" is input. If not, the process proceeds to step S220. The process of step A is as described above.

When the process proceeds to step S220, the detonation operation machine 50 determines whether or not the "delay time rewriting instruction" is input, and if the "delay time rewriting instruction" is input (Yes), step S225. If the "delay time rewriting instruction" is not input (No), the process is returned to step S210.

When the process proceeds to step S225, the detonation operation device 50 stores the individual ID, the delay time rewrite instruction (delay time rewrite command), and the ignition delay time in the control data, and proceeds to the process to step S230. In this case, the detonation operation machine 50 stores the delay time rewriting instruction (delay time rewriting command) in the "command" of the control data. Then, the detonation operation machine 50 extracts and extracts the ignition tool identification information which is an individual ID and the (setting) ignition delay time associated with the ignition tool identification information based on the setting information shown in FIG. 43. The ignition tool identification information is stored in the "ID" of the control data, and the extracted ignition delay time is stored in the "data" of the control data.

In step S230, the detonation operation machine 50 calculates the checksum (CS) by adding the respective values of the "individual ID", the "delay time rewriting instruction", and the ignition delay time stored in the control data. The control signal configured by the control data + CS is transmitted to the radio detonation tube 10 and the process proceeds to step S235.

In step S235, the detonation operation machine 50 determines whether or not the "interruption instruction" has been input, and if the "interruption instruction" is input (Yes), the process proceeds to step A and the "interruption instruction" is input. If not, the process proceeds to step S240. Since the process of step A is as described above, the description thereof will be omitted.

When the process proceeds to step S240, the detonation operating device 50 determines whether or not a predetermined time has elapsed since the control signal of step S230 was transmitted, and if the predetermined time has elapsed (Yes), a timeout is set. After making a determination, the process proceeds to step S255, and if the predetermined time has not elapsed (No), the process proceeds to step S245.

When the process proceeds to step S245, the detonation operating device 50 determines whether or not the response signal from the wireless detonator detonator 10 has been received, and when the response signal is received (Yes), the process proceeds to step S250. If the response signal has not been received (No), the process returns to step S235.

When the process proceeds to step S250, the detonation operation device 50 corresponds to the ID (ignition device identification information) included in the response signal, and the delay time which is the "operating state" included in the response signal. The rewriting state is stored, and the process proceeds to step S255. For example, as shown in FIG. 40, the delay time rewriting state included in the response signal may be "delayed rewriting completed" or "delayed rewriting failed". For example, when the delay time rewriting state included in the response signal is "delayed rewriting completed", the detonation operating device 50 corresponds to the ID (igniter identification information) included in the response signal in the setting information. Store "normal" in the "(response) delayed state" column (see FIG. 44). Further, when the delay time rewriting state included in the response signal is "delayed rewriting failure", the detonation operating device 50 corresponds to the ID (igniter identification information) included in the response signal in the setting information. The "abnormality" is stored in the "(response) delayed state" column (see FIG. 44). Further, the detonation operation device 50 sets the ignition delay time (ignition delay time after rewriting of the wireless detonation lightning tube) included in the response signal as the ID (ignition tool identification information) included in the response signal in the setting information. ) Corresponds to the "(response) delay time" column (see FIG. 44).

In step S255, the detonation operating device 50 determines whether or not the control data including the delay time rewriting instruction and the ignition delay time is transmitted to all the radio detonators 10 in steps S225 and S230. For example, the detonation operation device 50 sequentially has steps S225 to the radio detonation lightning tube corresponding to the uppermost ignition tool identification information in the setting information Z10B shown in FIG. 44 to the wireless detonation lightning tube corresponding to the lowermost ignition tool identification information. If the process of step S250 is performed and the control data including the delay time rewriting instruction and the ignition delay time is transmitted to all the radio detonation tubes (Yes), the process proceeds to step S260, and if not (No), the process proceeds to step S225. The processing is returned, and the control data including the next ignition tool identification information in the setting information is transmitted to the radio detonation lightning pipe corresponding to the ignition tool identification information.

When the process proceeds to step S260, the detonation operation device 50 determines whether or not the delay time rewriting state of all the radio detonators 10 is OK, and the delay time rewriting state of all the radio detonators. If all are OK (Yes), proceed to step S310, and if even one delay time rewriting state is not OK or if there is a radio detonator that did not send a response signal (No), go to step B. Proceed with processing. For example, in the detonation operation machine 50, when all the columns of "(response) delay state" in the setting information shown in FIG. 44 are "normal", and "(setting) ignition delay time" stored in advance, When the "(response) delay time" included in the response signal received from each radio detonation tube matches, it is determined that the delay time rewriting state of all the radio detonation tubes is OK, and the step is taken. The process proceeds to S310, and if not, the process proceeds to step B. Since the process of step B is as described above, the description thereof will be omitted.

When the process proceeds to step S310, the detonation operation device 50 blinks "ignition standby" and "interruption" in the process display unit 506A shown in FIG. 46 displayed on the display device, for example, and "ignition standby (instruction)". ) ”Or“ interruption (instruction) ”is displayed to remind the operator, and the process proceeds to step S315.

In step S315, the detonation operation machine 50 determines whether or not the "interruption instruction" has been input, and if the "interruption instruction" is input (Yes), the process proceeds to step A and the "interruption instruction" is input. If not, the process proceeds to step S320. The process of step A is as described above.

When the process is advanced to step S320, the detonation operation machine 50 determines whether or not the "ignition standby instruction" is input, and when the "ignition standby instruction" is input (Yes), the process proceeds to step S325. If "Ignition standby instruction" is not input (No), the process returns to step S310.

When the process proceeds to step S325, the detonation operation machine 50 stores the individual ID, the ignition standby instruction (ignition standby command) and the dummy data (00) in the control data, and proceeds to the process to step S330. In this case, the detonation operation device 50 stores an ignition standby instruction (ignition standby command) in the "command" of the control data. Then, the detonation operation machine 50 extracts the ignition tool identification information which is an individual ID based on the setting information shown in FIG. 44, stores the extracted ignition tool identification information in the control data "ID", and stores the extracted ignition tool identification information in the "data". Stores dummy data (00).

In step S330, the detonation operation machine 50 calculates the checksum (CS) by adding the respective values of the "individual ID", the "ignition standby instruction", and the dummy data (00) stored in the control data. The control signal configured by the control data + CS is transmitted to the radio detonator 10 and the process proceeds to step S335.

In step S335, the detonation operation machine 50 determines whether or not the "interruption instruction" has been input, and if the "interruption instruction" is input (Yes), the process proceeds to step A and the "interruption instruction" is input. If not, the process proceeds to step S340. Since the process of step A is as described above, the description thereof will be omitted.

When the process proceeds to step S340, the detonation operating device 50 determines whether or not a predetermined time has elapsed since the control signal of step S330 was transmitted, and if the predetermined time has elapsed (Yes), a time-out is set. After making a determination, the process proceeds to step S355, and if the predetermined time has not elapsed (No), the process proceeds to step S345.

When the process proceeds to step S345, the detonation operating device 50 determines whether or not the response signal from the wireless detonator detonator 10 has been received, and when the response signal is received (Yes), the process proceeds to step S350. If the response signal has not been received (No), the process returns to step S335.

When the process proceeds to step S350, the detonation operation device 50 corresponds to the ID (ignition device identification information) included in the response signal and is in the "operating state" of the ignition standby included in the response signal. The state is memorized and the process proceeds to step S355. For example, as shown in FIG. 40, the ignition standby state included in the response signal may be "ignition standby OK" or "ignition standby abnormality". For example, when the ignition standby state included in the response signal is "ignition standby OK", the detonation operation device 50 corresponds to the ID (ignition tool identification information) included in the response signal in the setting information "((Ignition tool identification information)". "Normal" is stored in the "Response) Standby state" column (see FIG. 45). Further, when the ignition standby state included in the response signal is "ignition standby abnormality", the detonation operation device 50 corresponds to the ID (ignition tool identification information) included in the response signal in the setting information "((Ignition tool identification information)". "Abnormal" is stored in the "Response) Standby state" column (see FIG. 45).

In step S355, the detonation operating device 50 determines whether or not the control data including the ignition standby instruction has been transmitted to all the radio detonators 10 in steps S325 and S330. For example, the detonation operation device 50 sequentially has steps S325 to the radio detonation lightning tube corresponding to the uppermost ignition tool identification information in the setting information Z10C shown in FIG. 45 to the wireless detonation lightning tube corresponding to the lowest ignition tool identification information. If the process of step S350 is performed and the control data including the ignition standby instruction is transmitted to all the radio detonation lightning tubes (Yes), the process proceeds to step S360, and if not (No), the process returns to step S325, and the setting information is set. The control data including the following ignition device identification information in the above is transmitted to the radio detonator lightning tube corresponding to the ignition device identification information.

When the process proceeds to step S360, the detonation operation device 50 determines whether or not the ignition standby states of all the radio detonator detonators 10 are all OK, and the ignition standby states of all the radio detonator detonators are all OK. If (Yes), the process proceeds to step S410, and if even one of the ignition standby states is not OK or if there is a radio detonator that has not transmitted a response signal (No), the process proceeds to step B. For example, the detonator 50 determines that the ignition standby state of all wireless detonators is OK when all the "(response) standby states" columns in the setting information shown in FIG. 45 are "normal". Then, the process proceeds to step S410, and if not, the process proceeds to step B. Since the process of step B is as described above, the description thereof will be omitted.

When the process is advanced to step S410, the detonation operation machine 50 blinks the "ignition count start" and "interruption" in the process display unit 506A shown in FIG. 46 displayed on the display device, for example, to "start the ignition count". A display is displayed to urge the operator to input "(instruction)" or "interruption (instruction)", and the process proceeds to step S415.

In step S415, the detonation operation machine 50 determines whether or not the "interruption instruction" has been input, and if the "interruption instruction" is input (Yes), the process proceeds to step A and the "interruption instruction" is input. If not, the process proceeds to step S420. The process of step A is as described above.

When the process is advanced to step S420, the detonation operation machine 50 determines whether or not the "ignition count start instruction" is input, and when the "ignition count start instruction" is input (Yes), the process is performed in step S425. If the "ignition count start instruction" is not input (No), the process returns to step S410.

When the process proceeds to step S425, the detonation operation machine 50 stores the global ID, the ignition count start instruction (which is the ignition count start command and corresponds to the ignition instruction or the ignition command) and the dummy data (00) in the control data. Then, the process proceeds to step S430. In this case, the detonation operation machine 50 stores the ignition count start instruction (ignition count start command) in the "command" of the control data. Then, the detonation operation machine 50 stores the global ID in the "ID" of the control data, and stores the dummy data (00) in the "data".

In step S430, the detonator operation machine 50 calculates the checksum (CS) by adding the respective values of the "global ID", the "ignition count start instruction", and the dummy data (00) stored in the control data. , The control signal configured by the control data + CS is transmitted to all the radio detonators 10 and the process is terminated.

In the processes of steps S20, S125, and S130 described above, the detonation operation device 50 (wireless ignition operation device) supplies driving energy and ignition energy toward the respective wireless detonation lightning tubes 10 (wireless ignition tool). It corresponds to the charge status request step of delivering and transmitting a control signal including a charge confirmation command (charge confirmation instruction) requesting confirmation of the charge status of the ignition energy.

Further, in the processes of steps S150 and S160 described above, the detonation operating device 50 (wireless ignition operating device) receives each response signal including the ignition tool identification information and the charging state, and is included in the received response signal. In the charging state determination step, which determines whether or not each wireless detonator (wireless ignition device) satisfies the charging state, which is one of the predetermined conditions, based on the ignition tool identification information and the charging state. Equivalent to.

Further, in the process of steps S225 and S230 described above, the ignition device identification corresponding to the wireless detonation lightning tube (wireless ignition device) determined by the detonation operation device 50 (wireless ignition operation device) to satisfy the charging state. Based on the information and the setting information, the ignition delay time corresponding to the ignition tool identification information is extracted, and the control signal including the ignition device identification information and the extracted ignition delay time and the delay time rewriting command is obtained. Corresponds to the delay time rewrite request step to be transmitted to the radio detonator tube (wireless ignition tool).

Further, the processes of the above steps S250 and S260 are performed by the detonation operation device 50 (wireless ignition operation device) from the respective wireless detonation lightning tubes 10 (wireless ignition tools) transmitted in the delay time rewriting response step. The response signal is received, and the ignition delay time stored in each wireless detonation lightning tube 10 (wireless ignition device) is grasped based on the ignition device identification information and the ignition delay time included in the received response signal. It is determined whether or not the ignition tool identification information and the ignition delay time included in the received response signal match the ignition tool identification information and the ignition delay time associated with the setting information, and the setting information is used. When all the associated ignition device identification information and the ignition delay time match, all the radio detonation lightning tubes 10 (wireless ignition devices) loaded in the charge hole are delayed, which is one of the predetermined conditions. It corresponds to the delay time rewriting state determination step of determining that the time rewriting state is satisfied.

Further, in the process of the above steps S360 to S430, in the detonation operation machine 50 (wireless ignition operation machine), all the radio detonation lightning tubes 10 (wireless ignition tools) loaded in the charging holes satisfy the predetermined conditions. If it is determined that the ignition is being performed, the ignition instruction (ignition count start instruction) is allowed to be input, and if the ignition instruction is permitted to be input, the ignition instruction (ignition count start instruction) is input, and the charging hole is charged. A control signal including an ignition command (ignition count start command) is transmitted to all the radio detonation tubes 10 (radio ignition tools) loaded in the charge hole, and all the radio detonation tubes loaded in the charge hole are transmitted. It corresponds to the ignition count start step of causing 10 (wireless ignition tool) to start counting the elapsed time.

Further, in the above steps S115, S135, S215, S235, S315, S335, S415, S515 to S530, when the interruption instruction is input by the detonation operation device 50 (wireless ignition operation device), the wireless detonator 10 Corresponds to the interruption request step of transmitting a control signal including an interruption command to (wireless ignition tool).

Further, the program on the side of the wireless ignition operation device for executing the processing of the above steps S20, S130, S230, S330, S430, S530 uses the detonation operation device 50 (wireless ignition operation device) and the respective wireless detonation lightning pipes 10 ( Control signal transmission means 501A (FIG. 34) that transfers driving energy and ignition energy to the wireless ignition tool) and transmits a control signal including a command indicating an instruction to the wireless detonation lightning tube 10 (wireless ignition tool). See).

It functions as a response signal receiving means 501B (see FIG. 34) that receives a response signal from 10 (wireless ignition tool) including the ignition device identification information and the operating state of the wireless detonator tube 10 (wireless ignition device) for the command.

Further, the wireless ignition operation device side program for executing the processing of the above steps S150, S160, S250, S260, S350, S360 includes the detonation operation device 50 (wireless ignition operation device) in the received response signal. Ignition tool that determines whether or not each wireless detonator tube 10 (wireless ignition tool) satisfies a predetermined condition based on the ignition tool identification information, the operating state, and the stored setting information. It functions as a state determination means 501C (see FIG. 34).

Further, the program on the side of the wireless ignition operating device for executing the processes of steps S225 and S230 describes the detonation operating device 50 (wireless ignition operating device) with the ignition tool identification information and the ignition tool based on the setting information. The ignition delay time associated with the identification information is extracted, and the control signal including the extracted ignition tool identification information, the ignition delay time, and the delay time rewriting command is sent to each radio detonator tube 10 (wireless ignition tool). It functions as a delay time rewriting request means 501D (see FIG. 34) to be transmitted toward.

Further, in the program on the side of the wireless ignition operation device that executes the processes of steps S360 to S420, the detonation operation device 50 (wireless ignition operation device) is loaded into all the wireless detonation lightning tubes 10 (the wireless ignition operation device). When it is determined that the wireless ignition tool) satisfies a predetermined condition, it functions as an ignition transmission permission means 501E (see FIG. 34) that permits transmission of a control signal including an ignition command (ignition count start command).

It functions as an ignition request transmitting means 501F (see FIG. 34) that transmits toward the ignition tool).

● [Processing procedure for wireless detonator 10 (wireless ignition tool) (Fig. 37)]
Next, an example of a processing procedure of each wireless detonator detonator 10 (wireless ignition tool) loaded in the charging hole will be described with reference to the flowchart shown in FIG. 37. The radio detonator 10 (wireless ignition tool) executes a radio crushing method based on the processing of the flowchart shown in FIG. 37 by executing a program on the side of the radio ignition tool stored in the storage means. Since each wireless detonator 10 loaded in the charge hole does not have a power source, it does not operate until the driving energy is supplied from the detonation operating device 50. When the wireless detonator detonator 10 is wirelessly supplied with driving energy from the detonation operating device 50, the process proceeds to step P10 shown in FIG. 37.

In step P10, the wireless detonator detonator 10 charges the driving energy supplied from the detonation operating device 50, and performs the following operations after step P20 with the charged driving energy.

In step P20, the wireless detonator detonator 10 proceeds to step P30 while charging the ignition energy supplied from the detonation operating device 50. When the electronic circuit 120 charges the circuit for both the ignition energy and the driving energy, the energy wirelessly supplied from the detonation operating device 50 is charged as the driving energy and the ignition energy.

In step P30, the wireless detonator detonator 10 determines whether or not a control signal has been received from the detonation operating device 50, and if the control signal is received (Yes), the process proceeds to step P40 and the control signal is received. If not (No), the process returns to step P20. When the value obtained by adding the "ID", "command", and "data" included in the received control signal does not match the value of "checksum (CS)" included in the received control signal. Determines that the received control signal contains noise and the like and cannot receive the correct control signal, discards the received control signal, and returns to step P20.

When the process proceeds to step P40, the radio detonator 10 determines whether or not the command included in the received control signal is an "interruption instruction", and if it is an "interruption instruction" (Yes). The process proceeds to step P60, and if it is not a "suspension instruction" (No), the process proceeds to step P110.

When the process proceeds to step P60, the radio detonator 10 executes the process at the time of interruption and proceeds to step P70. For example, the wireless detonator 10 safely discharges the charged ignition energy without using it for ignition as a process at the time of interruption.

In step P70, the radio detonator 10 stores the ignition device identification information, the interruption state, and dummy data (00) stored by itself in the response data, and proceeds to step P80. In this case, the radio detonator 10 stores the ignition tool identification information stored in the "ID" of the response data, and sets "interruption completed" or "interruption abnormality" shown in FIG. 40 in the "operating state". Store and store dummy data (00) in "data". For example, if the wireless detonator 10 can normally execute the interruption processing executed in step P60, it stores "interruption completed" in the "state", and if some abnormality occurs, the interruption processing is normally performed. If it cannot be executed, "suspension error" is stored in "operating status".

In step P80, the wireless detonator tube 10 calculates the checksum (CS) by adding the respective values of the "igniter identification information", the "suspended state", and the dummy data (00) stored in the response data. , The response signal composed of the response data + CS is transmitted to the detonation operation device 50, and the process is terminated. In this case, all the radio detonators loaded in the charging hole transmit the response signal, so if these radio detonators simultaneously transmit the response signal wirelessly, interference may occur. It is not preferable because it exists. Therefore, each radio detonator transmits a response signal (transmits with a time lag) when the response time (time from receiving the control signal to transmitting the response signal) set independently has elapsed. do). For example, each wireless detonator has a different response time set for each wireless detonator in association with the ignition tool identification information. The response signal is transmitted from the radio detonator 10 at a response frequency of 100 [MHz] or more and 1 [GHz] or less, and is transmitted at, for example, 315 [MHz] or 429 [MHz].

When the process proceeds to step P110, the wireless detonator 10 determines whether or not the "command" included in the received control signal is a "charge confirmation instruction", and if it is a "charge confirmation instruction". (Yes) proceeds to step P120, and if (No) is not a "charge confirmation instruction", the process proceeds to step P210.

When the process proceeds to step P120, the radio detonator 10 determines whether or not the "ID" included in the received control signal is a global ID, and if it is a global ID (Yes), step P160. If it is not a global ID (No), the process is returned to step P20.

When the process proceeds to step P160, the wireless detonator 10 confirms the charging state of the ignition energy stored in its own electronic circuit 120 and proceeds to step P170.

In step P170, the wireless detonator 10 stores the ignition device identification information, the charging state, and dummy data (00) stored in the response data, and proceeds to step P180. In this case, the wireless detonator 10 stores the ignition device identification information stored in the "ID" of the response data, and sets "charging completed" or "charging" as shown in FIG. 40 in the "operating state". Store and store dummy data (00) in "data". For example, when it is confirmed in step P160 that the ignition energy is charged to a predetermined amount, the wireless detonator 10 stores "charge completed" in the "operating state", and the wireless detonator 10 cannot be charged to the predetermined amount. If confirmed, "Charging" is stored in "Operating status".

In step P180, the wireless detonator tube 10 calculates the checksum (CS) by adding the respective values of the "igniter identification information", the "charge state", and the dummy data (00) stored in the response data. , The response signal composed of the response data + CS is transmitted to the detonation operation device 50, and the process is returned to step P20. In this case, since all the radio detonators loaded in the charging holes transmit the response signal, each radio detonator receives the response time (control signal) set independently as in step P80. When the time from that time to the transmission of the response signal has elapsed, the response signal is transmitted (transmitted with a time lag). For example, each wireless detonator has a different response time set for each wireless detonator in association with the ignition tool identification information.

When the process proceeds to step P210, the radio detonator 10 determines whether or not the "command" included in the received control signal is the "delay time rewrite instruction", and determines whether the "delay time rewrite instruction" is used. If (Yes), the process proceeds to step P220, and if it is not a “delay time rewrite instruction” (No), the process proceeds to step P310.

When the process proceeds to step P220, the radio detonator 10 determines whether or not the "ID" included in the received control signal is not a global ID but an individual ID (igniter identification information), and is global. If it is an individual ID instead of an ID (Yes), the process proceeds to step P230, and if it is not (a global ID) (No), the process returns to step P20.

When the process proceeds to step P230, whether or not the ignition tool identification information stored in the "ID" of the received control signal of the wireless detonator 10 matches the ignition device identification information stored by itself. If they match (Yes), the process proceeds to step P260, and if they do not match (No), the process returns to step P20.

When the process proceeds to step P260, the radio detonator 10 rewrites the ignition delay time stored by itself into the "ignition delay time" included in the received control signal, stores it, and proceeds to step P270. Proceed with processing.

In step P270, the radio detonator 10 stores the ignition tool identification information, the delay state, and the ignition delay time stored in the response data, and proceeds to step P280. In this case, the radio detonator 10 stores the ignition device identification information stored in the "ID" of the response data, and the "delayed rewriting completed" or "delayed book" shown in FIG. 40 in the "operating state". "Replacement failure" is stored, and the ignition delay time read from its own storage means is stored in "data". For example, when the ignition delay time is rewritten in step P260, the wireless detonator 10 stores "delayed rewriting completed" in the "operating state" if the rewriting can be performed normally, and at the time of rewriting something. If an error occurs, "delayed rewriting failure" is stored in "operating status".

In step P280, the wireless detonator 10 calculates a checksum (CS) by adding the respective values of "igniter identification information", "delayed state", and "ignition delay time" stored in the response data. , The response signal composed of the response data + CS is transmitted to the detonator operating device 50, and the process is returned to step P20. In this case, not all the radio detonators loaded in the charge hole transmit the response signal, but only one radio detonator with the same ignition device identification information transmits the response signal, so that interference occurs. Does not occur. Therefore, when the response signal can be transmitted, the response signal is immediately transmitted (transmitted without a time difference).

When the process proceeds to step P310, the radio detonator 10 determines whether or not the "command" included in the received control signal is an "ignition standby instruction", and if it is an "ignition standby instruction". (Yes) proceeds to step P320, and if it is not an “ignition standby instruction” (No), the process proceeds to step P410.

When the process proceeds to step P320, the wireless detonator 10 determines whether or not the "ID" included in the received control signal is not a global ID but an individual ID (igniter identification information), and is global. If it is an individual ID instead of an ID (Yes), the process proceeds to step P330, and if it is not (a global ID) (No), the process returns to step P20.

When the process proceeds to step P330, the radio detonator 10 determines whether or not the ignition tool identification information stored in the "ID" of the received control signal matches the ignition device identification information stored by itself. If they match (Yes), the process proceeds to step P360, and if they do not match (No), the process returns to step P20.

When the process proceeds to step P360, the radio detonator 10 executes the process during ignition standby and proceeds to step P370. The specific processing as the processing during the ignition standby will be omitted.

In step P370, the radio detonator 10 stores the ignition device identification information, the standby state, and dummy data (00) stored by itself in the response data, and proceeds to step P380. In this case, the radio detonation tube 10 stores the ignition tool identification information stored in the "ID" of the response data, and "ignition standby OK" or "ignition standby abnormality" shown in FIG. 40 in the "operating state". , And store dummy data (00) in the "data". For example, when the wireless detonator 10 executes the process during ignition standby in step P360, it stores "ignition standby OK" in the "operating state" if it can be executed normally, and if any abnormality occurs, it stores "ignition standby OK". Store "Ignition standby error" in "Operating status".

In step P380, the wireless detonator tube 10 adds the respective values of "igniter identification information", "standby state", and "dummy data (00)" stored in the response data to obtain a checksum (CS). The calculated response signal composed of the response data + CS is transmitted to the detonation operating device 50, and the process is returned to step P20. In this case, not all the radio detonators loaded in the charge hole transmit the response signal, but only one radio detonator with the same ignition device identification information transmits the response signal, so that interference occurs. Does not occur. Therefore, when the response signal can be transmitted, the response signal is immediately transmitted (transmitted without a time difference).

When the process proceeds to step P410, the radio detonator 10 determines whether or not the "command" included in the received control signal is the "ignition count start instruction", and the "ignition count start instruction" is used. If there is (Yes), the process proceeds to step P420, and if it is not the "ignition count start instruction" (No), the process returns to step P20.

When the process proceeds to step P420, the radio detonator 10 determines whether or not the "ID" included in the received control signal is a global ID, and if it is a global ID (Yes), step P460. If it is not a global ID (No), the process is returned to step P20.

When the process proceeds to step P460, the radio detonator 10 counts the elapsed time after receiving the control signal this time (or after reaching step P460), and proceeds to step P470.

In step P470, the radio detonation tube 10 determines whether or not the elapsed time counted has reached the memorized ignition delay time, and if the elapsed time reaches the ignition delay time (Yes), the step The process proceeds to P480, and if the elapsed time has not reached the ignition delay time (No), the process returns to step P460.

When the process proceeds to step P480, the radio detonator 10 ignites using the charged ignition energy.

The processing of the above steps P160 to P180 is performed by the ignition tool identification information and one of the operating states in each wireless detonation tube (wireless ignition tool) that has received the control signal including the charge confirmation command (charge confirmation instruction). It corresponds to a charge state response step in which a response signal including a certain charge state is transmitted to the detonation operation device 50 (wireless ignition operation device).

Further, in the process of steps P220 to P280 described above, the wireless detonator tube 10 (wireless ignition tool) that has received the control signal including the ignition tool identification information, the ignition delay time, and the delay time rewriting command (delay time rewriting instruction). When the ignition tool identification information included in the received control signal and the ignition tool identification information stored by itself match, the ignition delay time included in the received control signal is stored. Corresponds to the delay time rewriting response step in which a response signal including the memorized (rewritten) ignition delay time and its own ignition tool identification information is transmitted to the detonation operation device 50 (wireless ignition operation device). ..

Further, the process of steps P40 to P80 corresponds to an interruption execution step in which the wireless detonator 10 (wireless ignition tool) puts itself in an interrupted state when a control signal including an interrupt command is received.

Further, in the processing of the above steps P80 and P180, the response time, which is the time from the reception of the control signal to the transmission of the response signal, is set by the wireless detonation tube 10 (wireless ignition tool). It has a interference avoidance step that sets a different time for each 10 (wireless ignition device).

Further, the radio igniter side program for executing the processes of the above steps P60 to P80, P160 to P180, P260 to P280, and P360 to P380 uses the radio igniter tube 10 (wireless igniter) as the detonator operator 50 (wireless type). When a control signal including a command indicating an instruction to the wireless detonation lightning tube 10 (radio ignition tool) is received from the ignition operation device), a response signal including the ignition device identification information and its own operating state to the command is detonated. It functions as a response signal transmitting means 131A (see FIG. 27) that transmits to the operating device 50 (wireless ignition operating device).

Further, in the radio ignition tool side program for executing the above steps P210 to P280, the radio ignition lightning tube 10 (wireless ignition tool) is ignited from the detonation operation device 50 (wireless ignition operation device), and the ignition device identification information and the ignition delay. When a control signal including a time and a delay time rewrite command is received, if the ignition device identification information included in the received control signal and the ignition device identification information stored by the user match, the ignition device identification information is stored. The ignition delay time is rewritten to the ignition delay time included in the received control signal, and the delay time rewriting execution means 131B (see FIG. 27) is used.

Further, in the program on the side of the wireless ignition tool that executes the above steps P410 to P480, the ignition command (ignition count start command) is transmitted from the detonation operation device 50 (wireless ignition operation device) to the wireless detonation lightning tube 10 (wireless ignition device). ) Is received, the count of the elapsed time since the reception of the control signal is started, and the ignition is ignited when the elapsed time reaches the memorized ignition delay time. It functions as means 131C (see FIG. 27).

● [Second embodiment (FIGS. 47 to 54)]
In the first embodiment shown in FIGS. 1 to 46, an example of a wireless crushing system 1 using an explosive unit 20 having an explosive 36 (parent die 36A, expansion die 36B) has been described. In the second embodiment shown in FIGS. 47 to 54, an example of the wireless crushing system 205 using the non-explosive unit 320 in which the non-explosive crushing agent 201 is contained in the medicine cylinder 202 will be described.

Expectations for non-explosive blasting technology are increasing due to the reduction of environmental burden and the drastic decrease of skilled blasting engineers in tunnel excavation and building demolition. In response to such expectations for non-explosive blasting technology, various non-explosive blasting technologies have been put into practical use in which crushed objects such as tunnel excavated surfaces and concrete buildings are crushed by applying thermite reaction. This non-explosive blasting technique uses high-temperature, high-pressure steam expansion pressure generated by the thermite reaction. For example, there is a product marketed under the name of Gunsizer (Nippon Koki Co., Ltd., registered trademark), which is said to be safer than gunpowder because it applies energy to the object to be crushed relatively slowly. ing.

Although it has been replaced with the antenna 265, the appearance, the function, and the like are the same, so the description thereof will be omitted. In the example of FIG. 47, an example in which the distance L1 is set to 0 [m] is shown.

As shown in FIGS. 48 and 49, the non-explosive unit 320 includes a plastic medicine cylinder 202 formed in a bottomed cylinder shape with one end closed, and a non-explosive crushing agent 201 housed in the medicine cylinder 202. And a wireless ignition tool 310 attached to the other end side of the medicine cylinder 202 and closing the other end side. The wireless ignition tool 310 has a receiving antenna 311 on the ignition tool side, a transmitting antenna 318 on the ignition tool side, an ignition unit 314, and a control unit 12, and is housed in a control case 162 and a protective case 165. Since the igniter side receiving antenna 311 is the same as the detonating side receiving antenna 11 and the igniting tool side transmitting antenna 318 is the same as the detonating side transmitting antenna 18, these explanations will be omitted. Further, since the same applies to the transmission auxiliary antenna 19, the description thereof will be omitted.

FIG. 48 shows an example in which one non-explosive unit 320 is loaded in the charge hole 40, and FIG. 49 shows an example in which a plurality of non-explosive units 320 are loaded in the charge hole 40. Each of the non-explosive unit 320 has a medicine cylinder 202 containing the non-explosive crushing agent 201 and a radio igniter 310. When a plurality of non-explosive units 320 are loaded in the charge hole 40, as shown in FIG. 49, the wireless ignition tool 310 and the ignition device side transmission antenna 318 are not connected to the charge hole 40. A plurality of (two in the example shown in FIG. 49) non-explosive unit 320 to which the transmission auxiliary antenna 19 is attached are sandwiched between the spacers 25 made of synthetic resin and the like (or spacers). 25 may be omitted and a predetermined gap may be arranged), and the components may be loaded in series and covered with a sealing material 22 such as clay.

Further, FIG. 50 shows an example of a circuit block diagram illustrating the configuration of the wireless ignition tool 310. With respect to the circuit block diagram of the first embodiment shown in FIG. 27, the electronic circuit 120 is the same, the igniter side receiving antenna 311 is the same as the detonator side receiving antenna 11, and the igniter side transmitting antenna 318 is the same. It is the same as the detonating side transmitting antenna 18. The circuit block diagram of the second embodiment shown in FIG. 50 differs from the circuit block diagram of the first embodiment shown in FIG. 27 in the ignition unit 314. The differences will be mainly described below.

The ignition unit 314 has an ignition circuit 3141, an electric bridge line 3142, a non-explosive ignition agent 3143, a non-explosive ignition agent 3144, and the like. In the ignition circuit 3141, when the ignition switch circuit 138 is short-circuited, electric power (energy for ignition) is supplied from the electronic circuit drive power storage device 127, and the electric bridge line 3142 is energized. The electric bridge line 3142 is formed of, for example, a platinum-iridium line or the like, and is arranged in the non-explosive ignition agent 3143. The electric bridge line 3142 converts the energized electric energy into heat energy and ignites the non-explosive ignition agent 3143 in the vicinity of the electric bridge line 3142.

Then, the ignited non-explosive ignition agent 3143 ignites to the non-explosive ignition agent 3144, and the non-explosive ignition agent 3144 is ignited. As a result, when the non-explosive ignition agent 3144 is ignited, the non-explosive crushing agent 201 shown in FIGS. 48 and 49 is ignited, and the steam expansion pressure of high heat and high temperature (for example, about 2000 ° C to 3000 ° C) is caused by the thermite reaction. Occurs. Here, the composition of the non-explosive igniter 3143 is composed of, for example, C ₆ H ₃ NO ₄ Pb, KMnO ₄ , B, BaCr ₀₄ and the like. The composition of the non-explosive ignition agent 3144 is composed of, for example, Al, CuO, S, B and the like.

Then, using the wireless ignition operating device 250 (equivalent to the detonation operating device 50) and the wireless ignition tool 310 in the second embodiment described above, FIGS. 35 to 46 in the first embodiment. The crushed portion can be crushed appropriately and safely by the wireless crushing method described with reference to. That is, the wireless ignition operation device 250 is equipped with the wireless ignition operation device side program that executes the process shown in FIG. 36, and each wireless ignition tool 310 is caused to execute the process shown in FIG. 37. Install the program. Then, by the wireless crushing method described in the first embodiment, the same crushing as in the first embodiment can be executed.

In addition to the above-mentioned crushing of the face surface of the tunnel, the non-explosive unit 320 can be used for crushing huge stones, cutting concrete columns (partial demolition of building floors, dismantling of bridges, etc.), and underwater huge stones or concrete structures. It can be used for various crushing such as crushing. For example, FIGS. 51 to 53 show an example of crushing a concrete pillar in a space surrounded by an outer wall of a structure such as a building, FIG. 51 shows a perspective view of a state before crushing, and FIG. 52 is a diagram. 51 shows a cross-sectional view seen from the AA direction, and FIG. 53 shows a perspective view of the state after crushing with respect to FIG. 51.

As shown in FIGS. 51 and 52, the structure 210 has a floor surface 242, a side wall surface 243, and a ceiling surface 244, and two concrete columns 220 are erected from the floor surface 242 to the ceiling surface 244. An example is shown. Further, a plurality of reinforcing bars 230 are embedded in the concrete column 220. A plurality of reinforcing bars 230 are embedded vertically and horizontally, but in FIGS. 51 to 53, only two reinforcing bars embedded in the vertical direction are described as an example.

As shown in FIG. 51, the wireless crushing system 205 is the same as the wireless crushing system 205 shown in FIG. 47, that is, the wireless ignition operating device 250, the bus 262, the relay device 251 and the auxiliary bus 261. It has 260, a cable 266 for the receiving antenna on the ignition operating machine side, a receiving antenna 265 on the ignition operating machine side, and the like. For example, the transmission antenna 260 on the ignition operation device side is stretched by using the floor surface 242, the side wall surface 243, and the ceiling surface 244. Since the configuration and operation of the wireless crushing system 205 are the same as those of the wireless crushing system 205 shown in FIG. 47, the description thereof will be omitted.

Further, the concrete pillar 220 is perforated with a plurality of charge holes 40. In the example of FIG. 51, 24 holes are drilled on the side of the transmission antenna 260 on the ignition operator side and 24 holes on the side opposite to the transmission antenna 260 on the ignition operation device side at the crushed portion 241. A non-explosive unit 320 is loaded in each charge hole 40 (see FIG. 52). The loading state of the non-explosive unit 320 is the same as in FIG. 48 or FIG. 49. Further, the reinforcing bar 230 in each charge hole 40 is cut when the charge hole 40 is drilled. Further, even if the reinforcing bar is present in the vicinity of the non-explosive unit 320, the energy for driving the electronic circuit 120, the ignition energy, and the control signal are appropriately wirelessly transmitted from the transmission antenna 260 on the ignition actuator side to the non-explosive unit 320. Can be handed over to.

FIG. 53 shows an example of the state immediately after crushing. The concrete part of the crushed portion 241 is crushed by the non-explosive unit 320, and a part of the reinforcing bar 230 may remain without being crushed. No problem.

Here, as shown in FIG. 54, the transmission antenna 260 on the ignition operation device side has a plurality of circumferences such as two loops on the ceiling surface 244 so as to surround the ends of all the concrete columns 220 on the ceiling surface 244 side. It may be stretched, or it may be stretched so that it is wound only once. Then, the transmitting antenna 260 on the ignition operating device side may be pulled out from the side wall surface 243 along the ceiling surface 244 and connected to the relay device 251 via the auxiliary bus 261.

As a result, even if the reinforcing bar is present in the vicinity of the non-explosive unit 20, the energy for driving the electronic circuit 120, the energy for ignition, and the control signal are wirelessly transmitted from the transmission antenna 260 on the ignition actuator side to the non-explosive unit 20. Can be delivered properly. Further, even if each concrete pillar 220 is crushed, it is possible to prevent the transmitting antenna 260 on the ignition operating machine side and the auxiliary bus 261 from being buried in the concrete debris, and the concrete pillar 220 can be reused.

The wireless igniter side program is not limited to the appearance, structure, configuration, shape, method, processing procedure, program, etc. described in the present embodiment, and various changes and additions are made without changing the gist of the present invention. It can be deleted.

Further, the axis for winding the conductive wire in the sheet-shaped coil 117X for the X-axis (the axis orthogonal to the axis of the tubular magnetic material) is the axis for winding the conductive wire in the tubular coil 119 for the Z-axis (cylindrical magnetism). It is orthogonal to the axis of the body). Further, the axis of winding of the conductive wire in the sheet-shaped coil 117Y for Y-axis (the axis orthogonal to the axis of the tubular magnetic material) is the axis of winding of the conductive wire in the tubular coil 119 for Z-axis (cylindrical magnetism). It is orthogonal to the axis of the body) and is orthogonal to the axis of winding of the conductive wire in the sheet-shaped coil 117X for the X axis.

In the description of the present embodiment, a sheet-shaped tubular magnetic material 115 is used as the magnetic material of the detonating side receiving antenna 11, and a Z-axis tubular coil 119 and an X-axis sheet are used as the coil of the detonating side receiving antenna 11. An example using the shaped coil 117X and the sheet-shaped coil 117Y for the Y-axis has been described. However, the shape of the magnetic material of the detonating side receiving antenna 11 may be any shape, and the shape of the detonating side receiving antenna 11 may be any shape. That is, as the Z-axis receiving antenna 11Z, if the conductive wire is wound around the Z axis and around the first magnetic body, the shape of the first magnetic body and the shape of the coil around which the conductive wire is wound can be changed. , It may have any shape. Similarly, for the receiving antenna 11X for the X-axis, if the conductive wire is wound around the X-axis and around the second magnetic body, the shape of the second magnetic body is also the shape of the coil around which the conductive wire is wound. May have any shape. Similarly, for the Y-axis receiving antenna 11Y, if the conductive wire is wound around the Y-axis and around the third magnetic body, the shape of the third magnetic body is also the shape of the coil around which the conductive wire is wound. May have any shape.

The shape of the detonating side transmitting antenna 18 is not limited to the shape of the antenna portion 182 shown in the examples of FIGS. 20 and 28, and may be various shapes.

Moreover, the numerical value used in the explanation of this embodiment is an example, and is not limited to this numerical value.

The detonation side receiving antenna 11 described in the present embodiment is electronic with respect to the conventional antenna in which only the Z-axis tubular antenna (Z-axis receiving antenna) is arranged in the charging hole along the Z-axis direction. The drive energy and the ignition energy of the circuit can be received more "efficiently", and the radio control signal can be received more "efficiently". In addition, "efficiently" means that in the conventional antenna, for example, at the edge of the transmitting antenna on the detonation operation device side such as the charging positions P1a, P1c, P3a, P3c shown in the example of FIG. 4, the driving energy of the electronic circuit is used. In rare cases, the ignition energy could not be sufficiently received or the radio control signal could not be received. However, in the detonating receiving antenna of the present embodiment, as a result of many experiments by the inventor, the electron is received. It means that the case where the drive energy and the ignition energy of the circuit cannot be sufficiently received or the radio control signal cannot be received has never occurred. That is, "can be efficiently received" and "can be efficiently received" by the detonation side receiving antenna 11 described in the present embodiment means the energy for driving the electronic circuit as compared with the above-mentioned conventional antenna. It means that the ignition energy can be received more reliably and that the radio control signal can be received more reliably.
