The initiation side receiving antennas 11 (11A, 11B, 11C) of the wireless detonating detonator 10 correspond to the ignition tool side reception antennas, and the initiation side transmission antenna 18 corresponds to the ignition tool side transmission antenna.

● [Overall configuration of wireless shredding system 1 (FIG. 1) and loading state of parent die 36A and die increaser 36B into charging hole 40 (FIG. 2)]
As shown in FIG. 1, in the wireless shredding system 1, a parent die 36A and an increased die 36B are mounted in a charge hole 40 which is provided with a wireless detonation detonator and drilled in the face 41 (the blasting site). 2), the detonating operation device 50, the relay device 51, the detonating operation device side transmitting antenna 60, and the detoning operation device side receiving antenna 65.

  The detonating operation device 50 is disposed at a remote position away from the charge hole 40, and supplies a current to the detonating operation device side transmission antenna 60 through the blasting bus 62, the relay device 51, and the auxiliary bus 61 to perform the detoning operation. A magnetic field is generated around the machine-side transmission antenna 60 and a control signal (details of the control signal will be described later) is superimposed. Therefore, the detonator 50 transfers the driving energy, the ignition energy and the control signal of the electronic circuit 120 of the wireless detonator 10 to the wireless detonator 10 in a wireless manner via the initiator-side transmitting antenna 60. . The wireless detonating detonator 10 receives the energy for driving the electronic circuit 120, the energy for ignition, and the control signal in a wireless manner via the initiation-side receiving antenna 11 (see FIG. 10). Note that the frequency of the current that flows to the start-up controller side transmitting antenna 60 to deliver the driving energy and the ignition energy, and the operating frequency that is the frequency of the control signal are, for example, 100 kHz to 500 kHz. It is set. If the operating frequency is higher than 500 [kHz], standing waves are easily generated in the tunnel, which is not preferable.

  In addition, the detonating controller 50 transmits a wireless response signal from the detonating transmission antenna 18 (see FIG. 2) of the detonating detonator 10 to the detonator operating reception antenna 65, the detonator operating cable 66 and the relay device. 51 and blast bus 62 to receive. In addition, the response frequency which is a frequency of the response signal from the wireless detonation detonator 10 is set to 100 [MHz] or more and 1 [GHz] or less, for example. Note that setting the response frequency higher than 1 GHz is not preferable because it is difficult to pass through the rock. The response frequency is 500 [kHz] or more, and the output of the response signal is very small compared to the output of the drive energy, ignition energy, and control signal of the electronic circuit, and a standing wave is generated. There is no problem because the detonating operation machine side receiving antenna can be optimally installed.

  The relay device 51 has a tuning circuit, and is provided between the detonating controller 50 and the detonating operator-side transmitting antenna 60, and between the detonating operator 50 and the detonating operator-side receiving antenna 65. There is. The relay device 51 is connected to the detonator 50 via the blast bus 62, is connected to the detonator transmitter 60 via the auxiliary bus 61, and is detonated via the detonator cable 66. It is connected to the machine side reception antenna 65. The relay device 51 transfers the drive energy, the ignition energy, and the control signal of the electronic circuit to the wireless detonation detonator 10 from the detonator 50 to the drive energy and ignition of the electronic circuit from the detonator 50. The control signal including the energy for energy is output to the detonating operator side transmission antenna 60 via the auxiliary bus 61. Further, when the relay device 51 receives a response signal transmitted from the wireless detonating detonator 10 to the detonating controller 50, the detonating operator-side receiving antenna 65 and the detonating controller-side receive the response signal from the wireless detonating detonator 10 It is received via the antenna cable 66 and delivered to the detonator 50.

  The detonating operation machine side transmission antenna 60 is disposed in the vicinity of the face 41 (charge hole) and extends around the face or face, and the distance L1 from the face 41 is, for example, about 0 [m] to 1 [m]. It is looped along the floor 42, the sidewall 43 and the ceiling 44 at a position separated by a distance corresponding to a first predetermined distance. The distance L3 from the relay device 51 to the face 41 is, for example, about 50 m. Further, a distance L4 from the relay device 51 to the detonator 50 is, for example, about 100 m to 300 m. In addition, the detonating operation machine side transmission antenna 60 and the auxiliary bus bar 61 are newly tensioned each time the explosion occurs.

  The detonating operator-side receiving antenna 65 is, for example, a pole-like antenna, and is disposed at a distance of about a distance L2 (corresponding to a second predetermined distance) from the face 41 (a site to be detonated). 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 detonation detonator 10 is 100 [MHz] or more and 1 [GHz] or less, the shape is largely different from that of the detonating operation machine side transmission antenna 60, and it is necessary to wind it in a large loop. There is not. In addition, the detonating operation machine side reception antenna 65 and the detonation operation machine side receiving antenna cable 66 are not exchanged each time the blasting is performed, if the distance L2 from the blast site is apart to some extent.

  The main die 36A and the large die 36B, which are explosives, are loaded into the charge hole 40 to constitute the explosive unit 20, as shown in FIG. The charge hole 40 is, for example, a hole drilled to have 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, a parent die 36A and an increase die 36B are loaded in the charge hole 40, and a lid 22 is covered with a sealing material 22 such as clay. In this case, the parent die 36A is an explosive that is the lead at the time of being loaded into the charge hole 40, and is an explosive to which the wireless detonating detonator 10 is attached. Further, the increase die 36B is an explosive which is appropriately increased or decreased relative to the parent die 36A in this case.

  As shown in FIG. 2, the wireless detonating detonator 10 includes a substantially cylindrical initiation side reception antenna 11, a control unit 12, an initiation unit 14, and a initiation side transmission antenna 18. The initiation unit 14 is accommodated in the initiation side receiving antenna 11. Further, the inner diameter of the substantially cylindrical initiation side receiving antenna 11 is formed larger than the outer diameter of the explosive. The explosive is inserted into the initiation side receiving antenna 11 and the initiation part 14 is inserted, and integrated with the initiation side receiving antenna 11 to form a parent die 36 A, which is loaded into the charge hole 40. Further, the outer diameter of the initiation side receiving antenna 11 is equal to or less than the inner diameter of the charge hole 40. As shown in the example of FIG. 12, only the initiator unit 14 may be accommodated in the initiation side receiving antenna 11, and the control unit 12 may be disposed outside the initiation side receiving antenna 11.

  In addition, the display device 72 displays individual information (for example, an initiation delay time and an identification number) by which the operator can identify the wireless detonating detonator 10, and is attached to the wireless detonating detonator 10 via the cable 71. . The length of the cable 71 is set to a length that allows the display device 72 to reach the outside of the charge hole 40 when the parent die 36A is loaded into the charge hole 40. Thus, as shown in FIG. 2, the display 72 is positioned outside the loading hole 40 when the parent die 36A is loaded into the loading hole 40. The cable 71 and the display device 72 may be omitted. Further, although the example in which the display device 72 is attached to the wireless detonating detonator 10 via the cable 71 has been described in the present embodiment, the display device 72 may be directly attached to the wireless detonating detonator 10. If the display device is directly attached to the wireless detonation gun, the operator can not check the display device after loading it into the loading hole, but when loading it into the loading hole, load it while checking the display device. Can.

  In the following description, the influence of the positional relationship between the detonating operation machine side antenna (detonating operation machine side transmitting antenna, detonating operation machine side receiving antenna) and the wireless detonating detonator antenna (initiating side reception antenna, detonation side transmitting antenna) Regardless of this, it is possible to receive the drive energy, ignition energy and control signal of the electronic circuit more efficiently, and the freedom of selection of the response frequency of the response signal is high, and the response signal can be efficiently transmitted. The details of the wireless detonating detonator 10 which can be further miniaturized can be described.

[Direction of the magnetic field generated around the detonator-side transmitting antenna 60 (FIGS. 3 to 5)]
FIG. 3 is a diagram in which only the detonator control transmission antenna 60 is extracted from FIG. In FIG. 3, when current flows in the direction of the solid line arrow in the detonator control side transmitter antenna 60, a magnetic field as shown by an alternate long and short dash line is generated. When the direction of this magnetic field is taken as the axis of the detonation side reception antenna 11 of the wireless detonation detonator 10, when the conductive wire is wound around the axis, the energy for driving the electronic circuit and the ignition are most efficient. Energy can be received and wireless control signals can be efficiently received.

  FIG. 4 is a view of FIG. 3 viewed from the IV direction. The position of the charge hole of the face surface 41 substantially corresponding to the center of the wound start-up driver side transmission antenna 60 is indicated by the charge position P2b. A position corresponding to the edge of the detonating operation machine-side transmission antenna 60, the upper left position of the charging position P2b is indicated by the charge position P1a, and a position corresponding to the edge of the detonation operating machine-side transmission antenna 60. The upper right position of the charge position P2b is indicated by the charge position P1c, which is a position corresponding to the edge of the start-up operation machine side transmission antenna 60 and the position above the charge position P2b is the charge position It shows by P1b. Further, a position corresponding to the edge of the detonating operation machine-side transmission antenna 60 and a position on the left of the charging position P2b is indicated by the charge position P2a, and corresponds to the edge of the detonation operating machine-side transmission antenna 60 The position, which is the position to the right of the charge position P2b, is indicated by the charge position P2c. Further, a position corresponding to the edge of the detonating operation machine-side transmission antenna 60 and a lower left position of the charging position P2b is indicated by the charging position P3a, and corresponds to the edge of the detonation operating machine-side transmission antenna 60. The lower right position of the charge position P2b is indicated by the charge position P3c, which is a position corresponding to the edge portion of the start-up operation machine side transmission antenna 60 and is lower than the charge position P2b This is indicated by position P3b.

  FIG. 5 shows magnetic fields (generated around the transmission control antenna 60 on the side of the start-up controller) at each of the charge positions P1a to P1c, the charge positions P2a to P2c, and the charge positions P3a to P3c of the face 41 shown in FIG. (Example of the direction and magnitude of the magnetic field). At the charge position P2b corresponding to the approximate center of the detonator-side transmission antenna 60, the component of the magnetic field is only in the Z-axis direction, so an antenna in which a conductive wire is wound around the Z axis (the Z axis in the example of FIG. 8) The driving energy and the ignition energy of the electronic circuit can be efficiently received by the cylindrical coil 119 and the Z-axis cylindrical antenna (Z-axis receiving antenna 11Z) made of a cylindrical magnetic body. However, the magnitude of the magnetic field in the Z-axis direction decreases in the vicinity of the edge of the detonator-side transmitting antenna 60, 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 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 greater than the magnitude of the magnetic field in the Z-axis direction. At the charge position P1b, the magnitude of the magnetic field in the Z-axis direction is smaller than 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 charge positions P1a to P1c, the charge position P2a, the charge position P2c, and the charge positions P3a to P3c, which are the positions of the edge portion of the detonating operation machine side transmission antenna 60, conductive wires are wound around the Z axis. With only the turned antenna (in the example of FIG. 8, the Z-axis cylindrical coil 119 and the Z-axis cylindrical antenna (Z-axis reception antenna 11 Z by the cylindrical magnetic body)), energy and ignition for driving the electronic circuit efficiently It is not always possible to receive the wireless energy and efficiently receive the wireless control signal. Therefore, by using the initiation side receiving antenna 11 described below, the initiation side receiving antenna disposed (loaded) in the charge hole drilled at any position on the face surface 41 is more efficient. A start-up receiving antenna 11 is realized that can receive driving energy and ignition energy of an electronic circuit and can efficiently receive a wireless control signal.

  When the initiation side receiving antenna 11 of the wireless detonating detonator 10 is also used as an antenna for transmitting a response signal transmitted from the wireless detonating detonator 10 to the detonator, the response frequency is less than 100 MHz. Also, the reach of the response signal is short (for example, several [m]), which is not preferable. If the response frequency is higher than 1 GHz, it is likely to be absorbed by the rock, which is not preferable. If the response frequency is set to 100 [MHz] or more and 1 [GHz] or less, it is difficult to be absorbed by the rock, and a response signal with an appropriate reach distance can be obtained. However, the initiation side receiving antenna 11 capable of efficiently receiving the control signal (including the driving energy of the electronic circuit and the ignition energy) of the operating frequency of 100 kHz to 500 kHz is 100 MHz. If it is attempted to use the response signal of the response frequency of 1 GHz or less at the same time as the initiation side transmitting antenna capable of efficiently transmitting, the size of the antenna is increased, and the inside of the charge hole 40 shown in FIGS. There is a possibility that it can not be loaded.

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

● [Structure of wireless detonating detonator 10 (Figs. 6 to 12)]
FIG. 6 shows a wireless detonation detonator 10 in which the initiation side transmission antenna 18 is provided at a position where the control unit 12 is projected to the outside of the initiation side reception antenna 11 and is projected and a position not in contact with the initiation side reception antenna 11. It is a perspective view which shows the example (the 1) of the external appearance of. FIG. 7 shows an example of the appearance of the wireless detonating detonator 10Z having the initiation side transmitting antenna 18 provided at a position projecting to the outside of the initiation side receiving antenna 11 and a position not in contact with the initiation side receiving antenna 11 (part 2) FIG. FIG. 8 is an exploded perspective view of the wireless detonator 10 shown in FIG. When the response frequency is set to 100 [MHz] or more and 1 [GHz] or less, for example, the initiation side transmitting antenna 18 can be realized by an antenna of about several [cm] printed on the plane of the electronic circuit board (See FIG. 20). Therefore, the initiating side transmitting 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 initiating side transmitting antenna 18 can be integrated with the wireless detonating detonator. Is easy. In the example of FIG. 6, the initiation 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 initiation side transmitting antenna 18 is connected to the control unit 12 by the conductive wire 111.

  The control unit 12 is connected to the initiation side reception antenna 11, the initiation side transmission antenna 18, the initiation side reception antenna 11 and the initiation side transmission antenna 18, and causes the control unit 12 to ignite the initiation unit 14. It is comprised by the connected starting part 14. In addition, the electronic circuit 120 is accommodated in the control part 12 (refer FIG. 11, FIG. 12). 9 is a view of the initiation side receiving antenna 11 in FIG. 8 as viewed from the direction of IX in FIG. For example, as shown in FIG. 13, the initiation-side receiving antenna 11 is a base having a cylindrical base cylindrical body 114 (for example, a cylindrical acrylic material) and a sheet-like magnetic body (for example, ferrite) so as to have a thin cylindrical shape. A cylindrical magnetic body 115 wound around the outer circumference of a cylindrical body 114, a cylindrical coil (a cylindrical coil 119 for Z axis) provided on the outer circumference of the cylindrical magnetic body 115, and a sheet coil 117 (X axis for sheet) 117X and the sheet-like coil 117Y for Y-axis are coaxially arranged and configured. In the initiation side receiving antenna 11, three of the Z-axis cylindrical coil 119, the X-axis sheet-like coil 117X, and the Y-axis sheet-like coil 117Y are arranged along the direction of the Z-axis. The shape of the initiation side receiving antenna 11 is preferably a thin cylindrical shape, but it may be a thin cylindrical shape, and a cross section orthogonal to the axial direction (Z-axis direction) may be a circle, an ellipse, a polygon, etc. It may have any shape. The initiation 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 wireless detonator 10 shown in FIG. The initiation unit 14 is fixed to the control unit 12, and the control unit 12 is fixed to one opening of the initiation side receiving antenna 11. Further, a part of the control unit 12 protrudes from the initiation side receiving antenna 11 to the outside, and the initiation side transmission antenna 18 is provided at a position where the part 12 protrudes and a position not in contact with the initiation side receiving antenna 11. And, it is preferable that the space between the initiation side receiving antenna 11 and the control unit 12 be filled with an explosive. Thereby, since the explosive can be arranged to the deepest of the charge hole, the crushing effect can be improved. The initiator 14 is fixed so as to extend to the other opening side, and when the explosive is inserted from the other opening, the initiator 14 is inserted into the tip of the inserted explosive, and the parent die with the wireless detonator tube is inserted. An explosive is formed.

  Further, FIG. 11 shows an example of a cross-sectional view of a wireless blast detonator tube 10A having a configuration different from that of FIG. 10, in which the control unit 12 and the firing unit 14 are accommodated in the firing side receiving antenna 11. In the example shown in FIG. 11, the initiation side receiving antenna 11, the cylindrical magnetic body 115, and the base cylindrical body 114 are coaxially arranged and formed in a cylindrical shape. Then, the control unit 12 to which the initiator 14 is fixed is fixed to one of the openings by, for example, an adhesive 161. Further, the control unit 12 is configured of a control case 162, an electronic circuit 120 (an electronic circuit of a portion indicated by reference numeral 120 in FIG. 27), a buffer material 163, and the like. Further, in the example of FIG. 11, the initiation side transmitting antenna 18 is integrated with the electronic circuit 120 (see FIG. 28). A part of the control unit 12 protrudes from the initiation side reception antenna 11 to the outside, and the initiation side transmission antenna 18 is provided at a position where the control unit 12 protrudes and a position not in contact with the initiation side reception antenna 11. The initiator 14 is fixed so as to extend to the other opening side, and when the explosive is inserted from the other opening, the initiator 14 is inserted into the tip of the inserted explosive, and the parent die with the wireless detonator tube is inserted. An explosive is formed. In addition, the control case 162 is made of a material such as a resin that is relatively high in strength and easy to transmit radio waves, and an appropriate buffer material 163 is used to generate explosives placed in the adjacent charge hole. The shock wave may be attenuated by the control case 162 and the buffer 163 before being transmitted to the electronic circuit 120 so that the electronic circuit 120 is not damaged.

  FIG. 12 is a cross section of a wireless detonating detonator tube 10B having a different configuration from that of FIGS. 10 and 11 in which the initiator part 14 is accommodated in the initiator side receiving antenna 11 and the control unit 12 is arranged outside the initiator side receiving antenna 11. An example of the figure is shown. In the example shown in FIG. 12, the coaxially arranged receiving side antenna 11, cylindrical magnetic body 115 and base cylindrical body 114 are accommodated in a cylindrical protective case 165. The protective case 165 also has an isolation wall 166 that isolates the control 12 from the initiator 14 and the explosive. The control unit 12 is disposed on the opposite side to the triggering unit 14 with the isolation wall 166 interposed therebetween, and not outside the initiating reception antenna 11 but within the initiating reception 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 it is configured by the control case 162, the electronic circuit 120, the buffer material 163, and the like. Further, in the example of FIG. 12, the initiation side transmitting antenna 18 is integrated with the electronic circuit 120 (see FIG. 28). The control unit 12 protrudes from the initiation side reception antenna 11 to the outside, and the initiation side transmission antenna 18 is provided at a position where the control unit 12 protrudes and a position not in contact with the initiation side reception antenna 11. Then, as in the example of FIG. 11, the initiator 14 is fixed so as to extend toward the other opening, and when the explosive is inserted from the other opening, the initiator 14 is inserted into the tip of the inserted explosive. As a result, an explosive for a parent die with a wireless detonator is formed. Further, the control case 162 is formed of a material such as a resin having a relatively high strength and easy to transmit radio waves so that a shock wave generated when an explosive disposed in an adjacent charge hole detonates is transmitted to the electronic circuit 120. It may be previously damped by the control case 162 and the shock absorbing material 163 so that the electronic circuit 120 is not damaged. Furthermore, by arranging a part of the control case 162 outside the initiation side receiving antenna 11, the size of the electronic circuit 120 can be made equal to or larger than the inner diameter of the base cylindrical body 114. Freedom is improved. Furthermore, the region through which the explosive is inserted can be expanded, and the crushing effect can be improved.

[Structure of the initiation side receiving antenna 11 and the initiation side transmitting antenna 18 (FIGS. 13 to 20)]
FIG. 13 shows an exploded perspective view of the initiation side receiving antenna 11. The initiation side receiving antenna 11 is an antenna that receives the driving energy, the ignition energy, and the control signal of the electronic circuit in a wireless manner. The initiation side receiving antenna 11 includes a base cylinder 114, a cylindrical magnetic body 115, a sheet coil 117X for X axis, a cylindrical coil 119 for Z axis, and a sheet coil 117Y for Y axis. It is done. The base cylinder 114 may be omitted.

  The material of the cylindrical magnetic body 115 is a material of high magnetic permeability in which the magnetic pole disappears or reverses relatively easily among magnetic bodies, and it is made of, for example, iron, silicon steel, permalloy, sendust, permendur, ferrite Amorphous magnetic alloys, nanocrystal magnetic alloys, etc. are preferable, and ferrite is used in the present embodiment. The cylindrical magnetic body 115 is formed in a sheet shape, as shown in FIG. 13, and is wound around the outer peripheral surface of the base cylindrical body 114 to form a thin cylindrical shape. More preferably, the ends of the turns of the cylindrical magnetic body 115 are wound such that the gap 172 is substantially zero without overlapping, as shown in FIG. However, as shown in FIG. 13, one end of the winding of the cylindrical magnetic body 115 may overlap with the other end and may be wound so as to have the overlap portion 171, and The body 115 may be wound so as to be double or triple. The clearance 172 shown in FIG. 14 is within the allowable range if it is a minute clearance of about 1 [mm], for example, but it is not preferable if the clearance 172 is a clearance larger than the minute clearance. Also, as shown in FIGS. 8 and 13, the antenna axis J11, which is the axis of the cylindrical magnetic body 115, is parallel to the Z axis and can be said to be the Z axis.

  As shown in FIG. 13, the Z-axis cylindrical coil 119, the X-axis sheet-like coil 117X, and the Y-axis sheet-like coil 117Y are coaxially mounted to the base cylinder 114 and the cylindrical magnetic body 115. Thus, the initiation side receiving antenna 11 is formed. The initiation side reception antenna 11 is loaded in the charge hole so that the antenna axis J11 which is the axis of the initiation side reception antenna 11 coincides with the axial direction of the charge hole 40 (in this case, the Z-axis direction). Then, for the magnetic field of the component in the Z-axis direction in FIG. 5, a Z-axis tubular antenna (Z-axis tubular coil 119 having the Z-axis direction as the winding axis of the conductive wire and the tubular magnetic body The driving energy and the ignition energy of the electronic circuit can be efficiently received by the Z-axis receiving antenna 11Z (see FIGS. 6 and 7), and the wireless control signal can be efficiently received. In addition, for the magnetic field of the component in the X-axis direction in FIG. 5, the X-axis sheet-shaped antenna (X-axis antenna (X The driving energy and the ignition energy of the electronic circuit can be efficiently received by the axis receiving antenna 11X (see FIGS. 6 and 7), and the wireless control signal can be efficiently received. In addition, for the magnetic field of the component in the Y-axis direction in FIG. 5, a Y-axis sheet-shaped antenna (Y-axis antenna (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. In the example shown in FIG. 13, the base cylinder 114, the cylindrical magnetic body 115, the Z-axis cylindrical coil 119, the X-axis sheet-like coil 117X, and the Y-axis sheet-like coil 117Y. Although the example which comprised the initiation side receiving antenna 11 is shown, the base cylinder 114 may be abbreviate | omitted.

  As shown in FIGS. 6 and 7, the initiation side receiving antenna 11 has three antennas, that is, the Z axis receiving antenna 11 Z, the X axis receiving antenna 11 X, and the Y axis receiving antenna 11 Y, in the Z axis direction. Along the lines, they are formed in any order so as not to overlap. 6 and 7, the Z-axis receiving antenna 11Z is a Z-axis cylindrical antenna (Z-axis receiving) by the Z-axis cylindrical coil 119 and the cylindrical magnetic body 115 (corresponding to the first magnetic body). It is configured as an antenna 11Z). The X-axis receiving antenna 11X is configured as an X-axis sheet-like antenna (X-axis receiving antenna) by the X-axis sheet-like coil 117X and the cylindrical magnetic body 115 (corresponding to the second magnetic body). The Y-axis receiving antenna 11Y is configured as a Y-axis sheet-like antenna (Y-axis receiving antenna) by the Y-axis sheet-like coil 117Y and the cylindrical magnetic body 115 (corresponding to a third magnetic body). The first magnetic body, the second magnetic body, and the third magnetic body may be separately configured, or may be configured as a common magnetic body as described in the present embodiment.

  According to the results of various experiments by the inventor, the Z-axis cylindrical coil 119 is disposed at the center (the position where the Z-axis cylindrical coil is sandwiched between the X-axis sheet coil and the Y-axis sheet coil Is more preferred. For example, in the example of FIG. 15, the sheet coil for X axis 117 X at the left, the cylindrical coil 119 for Z axis at the center, and the sheet coil 117 Y for Y axis at the right are arranged. It is described as (117X, 119, 117Y). In the arrangement in which the Z-axis cylindrical coils 119 are arranged at the center, the arrangement of (117X, 119, 117Y) shown in FIG. 15 and the arrangement shown in FIG. 15 are rotated 90 ° around the Z-axis. There is an arrangement of the order of (117Y, 119, 117X).

However, the shape of the winding is not limited to a rectangular shape, and may be wound in a spiral (helical) shape or various polygonal shapes. Moreover, you may wind so that various shapes may be mixed. The Z-axis cylindrical coil, the X-axis sheet coil, and the Y-axis sheet coil may be created manually by the operator by winding the conductive wire 111 a predetermined number of times.

● [Circuit in control unit 12 of wireless detonating detonator 10 and in detonating unit 14 (FIG. 27)
Next, circuits (circuits of the electronic circuit 120 and the triggering unit 14) in the control unit 12 and the triggering unit 14 of the wireless detonating detonator 10 will be described using a circuit block diagram shown in FIG. FIG. 27 shows respective circuits (block diagram) of the electronic circuit 120 and the initiator 14 contained in the control unit 12 including the initiator side receiving antenna 11 and the initiator side transmitting antenna 18 shown in FIG. There is.

  The initiation side receiving antenna 11 includes an X-axis sheet-like coil 117X and an X-axis sheet-like antenna (X-axis receiving antenna) by a cylindrical magnetic body, a Z-axis cylindrical coil 119 and a Z-axis magnetic body A tubular antenna for Z axis (reception antenna for Z axis), a sheet coil 117Y for Y axis, and a sheet antenna for Y axis by a cylindrical magnetic body (reception antenna for Y axis) are provided. The X-axis sheet-like coil 117X is connected to the three-axis combining circuit 124 via a tuning circuit 121 configured of a variable capacitor or the like. Similarly, the Z-axis cylindrical coil 119 is connected to the three-axis combining circuit 124 via a tuning circuit 122 configured of a variable capacitor or the like. Similarly, the Y-axis sheet-like coil 117Y is connected to the three-axis combining circuit 124 via a tuning circuit 123 configured of a variable capacitor or the like. Thus, the conductive wire 111 is connected to each of the tuning circuits 121, 122, and 123 in each of the sheet coil for X axis 117X, the cylindrical coil for Z axis 119, and the sheet coil for Y axis 117Y. ing. Then, each of the tuning circuits 121, 122, 123 is connected to the three-axis combining circuit 124.

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

  The electronic circuit 120 includes tuning circuits 121, 122 and 123, a three-axis combining circuit 124, a CPU 131, a detection / demodulation circuit 125, a regulator 128, a modulation circuit 133, a transmission circuit 134, an ID storage device 132, and a storage device 127 for driving an electronic circuit. And an ignition switch circuit 138, a rectifier circuit 126, and the like. Each of the tuning circuits 121, 122, and 123 is a variable capacitor for adjusting the resonant frequency of the corresponding sheet-shaped coil for X-axis 117X, cylindrical coil for Z-axis 119, and sheet-shaped coil for Y-axis 117Y. And so on.

  The three-axis combining circuit 124 includes a sheet antenna for X axis (sheet coil 117X for X axis that constitutes a receiving antenna for X axis) and a sheet antenna for Y axis (for Y axis which constitutes a receiving antenna for Y axis) Energy and ignition of an electronic circuit input from the coil 117Y) and the Z-axis cylindrical antenna (Z-axis cylindrical coil 119 constituting the Z-axis receiving antenna) via the tuning circuits 121, 122 and 123 Energy and control signals are synthesized and output to the path 151 and the path 152. The route 151 is a route for taking in the received control signal, and the route 152 is a route for rectifying, storing, and voltage-converting the received energy. Then, the wireless control signal received via the path 151 and the detection / demodulation circuit 125 is taken into the CPU 131, and the driving energy (and for ignition) of the electronic circuit via the path 152 and the regulator 128 (constant voltage circuit) Energy) is used as a power source of an electronic circuit such as a CPU and is stored in an electronic circuit driving storage device 127.

  In the ID storage device 132, identification information unique to the wireless detonating detonator 10 is stored. 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 instruction for ignition (or when a predetermined ignition delay time has elapsed after receiving the command corresponding to the instruction for ignition), the control signal 156 causes the switch circuit 138 for ignition to be activated. Is controlled from the open state to the short circuit state, and energy stored in the electronic circuit drive storage device 127 (energy for driving the electronic circuit and energy for ignition) is output to the ignition circuit 141 to execute detonation. The CPU 131 also has storage means, and the storage means stores a wireless ignition tool side program. The response signal transmission unit 131A, the delay time rewriting execution unit 131B, and the delay ignition execution unit 131C will be described later.

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 storage device 127, and the ignition ball 142 is ignited. Then, when the ignition ball 142 is ignited, the priming charge 143 and the additive charge 144 are ignited, and the initiator 14 is ignited. Then, when the starter 14 is ignited, the parent die 36A shown in FIG. 2 is detonated.

[Example of integrating the electronic circuit 120 and the initiation side transmitting antenna 18 (FIG. 28)]
As described above, since the initiation side transmission antenna 18 may print the antenna part of a conductor of about several [cm] on an insulator, the initiation side transmission antenna 18 may be formed on the electronic circuit board constituting the electronic circuit 120. It is possible to form an antenna 18. Therefore, as shown in the example of FIG. 28, the antenna portion 182 can be printed on a part of the plate-like (or sheet-like) electronic circuit board 129 of the insulator. For this reason, the electronic circuit 120 and the initiation side transmitting antenna 18 can be integrated on the electronic circuit board 129, and 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 operation frequency is set to 100 [kHz] or more and 500 [kHz] or less. Since the initiation side receiving antenna 11 (reception-only antenna) of the wireless initiation detonator 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 detonating operation machine-side transmission antenna 60 (an antenna dedicated to transmission) shown in 1 can be made once or several times. Then, by supplying the current of the operation frequency to the start-up operation machine side transmission antenna 60, power is supplied to the control unit 12 (electronic circuit 120) of the wireless detonation detonator 10 and the energy for ignition is stored. The power supplied to the start-up controller side transmitting antenna 60 for power supply to the control unit 12 and storage can be relatively small power of about several tens of watts to several hundreds of watts. Furthermore, control of the wireless detonator is performed by a control signal superimposed on the current.

  Further, a detonating operation machine side receiving antenna 65 (an antenna for receiving only) is provided, and the frequency of the signal to be responded from the wireless detonating detonator 10 is set to 100 [MHz] or more and 1 [GHz] or less. As a result, it is possible to make the trigger side transmitting antenna 18 (the antenna dedicated to transmission) of the wireless detonating detonator smaller in size, and it is possible to transmit the response signal more efficiently, and the reach of the longer response signal ( For example, about 50 [m] can be realized.

  Further, the initiation side receiving antenna 11 described in the present embodiment can efficiently receive the drive energy, the ignition energy, and the wireless control signal of the electronic circuit from the magnetic field in the Z axis direction. Energy for driving the electronic circuit, energy for ignition, and control signal for wireless from the magnetic field in the X-axis direction and the cylindrical antenna for Z-axis (Z-axis receiving antenna) by Z-shaped coil 119 and cylindrical magnetic body Sheet-like coil 117X for X-axis and a sheet-like antenna for X-axis (cylindrical antenna for X-axis) by a cylindrical magnetic material, and energy for driving the electronic circuit and energy for ignition efficiently from the magnetic field in the Y-axis direction A sheet-like coil for Y-axis 117Y capable of receiving a wireless control signal and a sheet-like antenna for Y-axis (cylindrical receiving antenna for Y-axis) by a cylindrical magnetic body That. Therefore, even with the charge hole 40 drilled at any position on the face surface 41 shown in FIG. 1, it is possible to more efficiently receive the driving energy and the ignition energy of the electronic circuit and wireless control. It can receive a signal. Further, as shown in FIG. 2, by inserting an explosive into the cylindrical initiation side receiving antenna 11, more explosives can be loaded into the charge hole, and the explosion efficiency is improved. Can.

  In addition, the initiation side transmitting antenna is provided at a position projecting to the outside of the initiation side receiving antenna 11 and at a position not in contact with the initiation side receiving antenna, and the radio initiation detonator and the initiation side transmission antenna are integrated. Compared to the case of having a separate trigger side transmitting antenna connected separately, loading into the charge hole is easy, and disconnection of the conductive wire connecting the starting side transmission antenna and the wireless detonating detonator is properly avoided can do.

[Addition of the transmission auxiliary antenna 19 to compensate for the transmission from the initiating side transmission antenna 18 (FIGS. 29 to 33)]
As shown in FIG. 2, the wireless detonator 10 is loaded in the deepest part of the charge hole 40. Therefore, the initiating side transmitting antenna 18 transmitting the response signal from the wireless detonating detonator 10 is also at a deep position of the charge hole 40. Therefore, depending on the type of bedrock around the charge hole, etc., the transmission signal from the initiation side transmission antenna 18 may be cut off, and the transmission signal may not be efficiently transmitted toward the initiation operation machine side reception antenna 65. Is considered. Therefore, the transmission auxiliary antenna 19 is added to the wireless detonation detonator to supplement the transmission from the initiation side transmission antenna 18, so that the transmission signal can be efficiently transmitted to the initiation operator side reception antenna.

  FIG. 29 shows an example of the appearance of a wireless detonating detonator 10B in which a transmission auxiliary antenna 19 is added to the wireless detonating detonator shown in the sectional view of FIG. The wireless detonating detonator having the electronic circuit 120, the detonating side receiving antenna 11, the detonating side transmitting antenna 18, and the detonating unit 14 is accommodated in a cylindrical case, the protective case 165 and the control case 162, and the wireless detonating detonator It forms 10B. The shapes of the protective case 165 and the control case 162 are not limited to cylindrical but may be cylindrical. Further, the size of the control case 162 is a size capable of protecting and housing the electronic circuit 120 having the initiation side transmission antenna 18, and the diameter orthogonal to the antenna axis J11 is loaded in the charge hole 40 as shown in FIG. It is set to the possible diameter. The length along the antenna axis J11 in the control case 162 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 initiation side receiving antenna 11 and the initiation part 14, and the diameter orthogonal to the antenna axis J11 is a diameter that can accommodate the initiation side receiving antenna 11, and As shown in FIG. 30, the diameter is set to a diameter that can accommodate a part of the parent die 36A, and the diameter that can be loaded into the loading hole 40. Further, the length along the antenna axis J11 in the protective case 165 is such a length that can accommodate the initiation side receiving antenna 11 and the initiation part 14 without waste, and as shown in FIG. 30, can accommodate at least a part of the parent die 36A. 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 larger in one of the diameters than in the other. And may be the same. Further, the length of control case 162 (length along antenna axis J11) and the length of protection case 165 (length along antenna axis J11) are set such that one of them is longer than the other. It may be the same. Then, the transmission auxiliary antenna 19 having a predetermined length (the length set according to the length of the charge hole 40 shown in FIG. 30) is not connected to the initiation side transmission antenna 18 (the initiation side transmission antenna 18 And unconnected) attached to the wireless detonator 10B. The transmission auxiliary antenna 19 is made to have a predetermined length by a guiding portion 191 formed of a conductor such as metal or carbon and a lead portion 192 formed of a conductor such as metal or carbon. The guiding portion 191 and the lead portion 192 are joined. The “predetermined length” is the side of the other end of the transmission auxiliary antenna 19 (opposite to the side attached to the protective case or the control case) when the wireless detonating detonator tube 10B is loaded into the charge hole 40 as shown in FIG. Side) is set to a length longer than the length that can reach the opening 45 of the loading hole 40.

  The guiding portion 191 is not connected to the initiating side transmitting antenna 18 on the side of one end of the transmission auxiliary antenna 19, and is attached to at least one of the outside and the inside of the protective case 165 and a part of the control case 162. ing. Although the induction section 191 (transmission auxiliary antenna 19) and the initiation side transmission antenna 18 are not connected, it is preferable that the shortest distance from the induction section 191 to the initiation side transmission antenna 18 be as short as possible. The example of FIG. 29 shows an example in which the guiding portion 191 is attached to the outside of a part of the protective case 165, and from one end to the other end of the protective case 165 so as to be substantially parallel to the antenna axis J11. , And the example which attached the induction | guidance | derivation part 191 is shown. In this case, when the guiding portion 191 is 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 guiding unit 191 contactlessly receives the transmission signal wirelessly transmitted from the initiation side transmission antenna 18 with respect to the initiation side transmission antenna 18, and propagates the received transmission signal to the lead unit 192. Although FIG. 29 shows an example in which the guiding portion 191 is set to the length from one end to the other end of the protective case 165, the length in the axial direction parallel to the antenna axis J11 in the guiding portion 191 is particularly Not limited Further, the width in the circumferential direction around the antenna axis J11 in the induction portion 191 is set to about 10 [mm] or less so as not to cover the initiation side receiving antenna 11.

The lead portion 192 is on the other end side of the transmission auxiliary antenna 19 and is not connected to the initiation side transmission antenna 18, and is extended away from the protective case 165 and the control case 162. In the example of FIG. 29, the lead portion 192 having a conductive wire covered with an insulator is joined to the induction portion 191 by solder or the like at the joint portion 193 and extended so as to be separated from the protective case 165 or the control case 162. An example is shown. The lead portion 192 transmits the transmission signal propagated from the guiding portion 191 from the hanging portion 194 from the opening 45 of the charge hole 40 in FIG. In this case, the hanging portion 194 serves as a substantial transmission antenna. The drooping length L19 of the drooping portion 194 in FIG. 30 is preferably 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 × 10 ⁸ [m / s] / 315 [MHz] = approximately 1 [m]. In this case, the sag length L 19 is approximately It is preferable to set it as 25 [cm] or more.

  FIG. 30 shows a state in which the wireless detonating detonator shown in FIG. 29 is the wireless detonating detonator 10B shown in FIG. 29, as opposed to FIG. 2 showing a state in which the explosive unit using the wireless detonating detonator is loaded into the charge hole 40. . The auxiliary transmission antenna 19 is drawn out from the opening 45 of the charge hole 40 and has a hanging portion 194. The hanging length L19 is preferably set to 1/4 or more of the wavelength of the transmission signal. Further, the cable 71 can be omitted by attaching the display device 72 using the transmission auxiliary antenna 19 instead of the cable 71 in FIG. In the step of loading the explosive, as shown in FIG. 30, the parent die 36A, which is an explosive with the wireless detonating detonator 10B attached, and the expansion die 36B, which is an explosive without the wireless detonating detonator 10B attached (ie, explosive The unit 20 is loaded into the charge hole 40 and loaded into the charge hole 40 so that the other end side (the lead portion 192 side) of the transmission auxiliary antenna 19 hangs down from the opening 45 of the charge hole 40.

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

  Further, FIG. 32 shows an example in which the guiding portion 191 is attached (attached) from one end of the control case 162 to the other end so as to be substantially parallel to the antenna axis J11. Although FIG. 32 shows an example in which the guiding portion 191 is set to a length from one end to the other end of the control case 162, the length in the axial direction parallel to the antenna axis J11 in the guiding portion 191 is There is no particular limitation. Further, the width in the circumferential direction around the antenna axis J11 in the guiding portion 191 is not particularly limited.

  Further, FIG. 33 shows an example in which the induction portion 191 is wound and attached around the control case 162 so as to go around the antenna axis J11. Although FIG. 33 shows an example in which the guiding portion 191 is continuously wound around the control case 162, the length of the guiding portion 191 in the circumferential direction around the antenna axis J11 is not particularly limited. Further, the width in the axial direction parallel to the antenna axis J11 in the guiding portion 191 is not particularly limited.

  The guiding 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 guiding part 191 is attached to the outside of a part of the protective case 165, but the guiding part 191 may be attached to the inside of the protective case 165. One part may be attached to the inside of the protective case and the other may be attached to the outside of the protective case. Further, the induction portion 191 and the lead portion 192 may be formed of one continuous conductive line (in this case, the joint portion 193 is omitted). In addition, since the transmission auxiliary antenna 19 is not connected to the initiation side transmission antenna 18, static electricity, leakage current (from the surrounding high voltage wire or the like) or stray (flowing in the ground due to any cause) may occur in the charge hole 40. Even when there is a current and these are picked up by the transmission auxiliary antenna 19, it is possible to prevent the transmission to the electronic circuit 120 through the initiation side transmission antenna 18. As mentioned above, although various examples can be considered as an example of the induction | guidance | derivation part 191, in the induction | guidance | derivation part 191 shown to the example of FIG. 29, as an example of the preferable form of the induction | guidance | derivation part 191, diameter is about 0.4 [mm]. A lead portion 191 formed by attaching the lead wire (copper wire) of the above-mentioned type to the surface of the protective case 165 with an adhesive or the like is conceivable.

● [Configuration of detonator 50 (wireless ignition controller) (Fig. 34)]
Next, the configuration of the initiator 50 will be described using the block diagram shown in FIG. The initiation control unit 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 the operator is input. Further, the display device 506 is, for example, a liquid crystal monitor, and displays the operation state of the detonating operation device 50 and an instruction from the operator. Note that the display device 506 may be a touch monitor.

  The storage device 503 stores a wireless ignition controller side program. The CPU 501 executes the wireless ignition controller side program read from the storage device 503 to execute “processing of the detonator 50 (wireless ignition controller)” described later. The details of the control signal transmission unit 501A, the response signal reception unit 501B, the ignition tool state determination unit 501C, the delay time rewriting request unit 501D, the ignition transmission permission unit 501E, and the ignition request transmission unit 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 detonator controller transmission antenna 60 via the blast bus 62, the relay device 51, and the auxiliary bus 61. In the receiving circuit 505, the response signal wirelessly transmitted from the wireless detonating detonator is input through the detonating operation machine side reception antenna 65, the detonation operation machine side reception antenna cable 66, the relay device 51, and the blasting bus 62, and input The received response signal is output to the CPU 501. Further, the switching circuit 507 switches the transmission / reception path in the relay device 51 based on the switching signal from the CPU 501.

● [Wireless shredding process (Fig. 35)]
Next, the procedure of the wireless crushing process of the worker at the crushing site will be described using the flowchart of FIG. As shown in the wireless crushing process of FIG. 35, the worker performs the charge 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 process proceeds in the order of the manipulator installation process K50 and the crushing process K60.

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

  In the loading step K20, as shown in FIG. 2, the operator loads the parent die 36A and the increase die 36B attached with the wireless detonating detonator 10 into the drilled charge holes, and displays them outside the charge holes. Pull out the device 72. Each wireless detonating detonator 10 stores ignition tool identification information including at least one of an ID and a serial number capable of identifying each wireless detonating detonator, and the corresponding ignition tool identification information is described in the display device 72. ing. The operator reserves in advance which charge hole the wireless detonator of which ignition tool identification number has been loaded. For example, as in the setting information shown in FIG. 42, the ignition device identification information may be stored in association with the charge hole information indicating the position of each charge hole. The method for storing the ignition tool identification information in correspondence with the charge hole information may be stored by any method.

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

  In the ignition operation machine side reception antenna installation step K40, the operator installs the detonation operation machine side reception antenna 65 at a position separated by a distance L2 from the fracture point, as shown in FIG. Then, the initiation control unit side reception antenna 65 and the relay device 51 are connected by the initiation control unit side reception antenna cable 66.

  In the wireless ignition controller installation step K50, the operator installs the detonating controller 50 at a safe place sufficiently away from the crushing point and connects the blasting bus 62 to the detonating controller 50, as shown in FIG. . The operator prepares in advance a shield box surrounded by an electromagnetic shield member that shuts off wireless driving energy, ignition energy, control signal and response signal of the electronic circuit. The inner surface of the shield box is an insulator without the conductor being exposed. Then, the operator brings it to the shredding site, but if there are excess wireless detonating detonators that were not loaded in the charge hole, these excess detonating detonating detonators are used as the detonator 50 (wireless ignition type detonator) By blocking radio waves radiated from the electronic circuit, the activation of the electronic circuit is prevented, and it is safely stored in the shield box. As a result, it is possible to prevent the activation of the surplus wireless detonating detonator 10 (wireless ignition tool) by the radiation electric wave from the detonator 50 (wireless ignition operator), and the crushing work and the surplus wireless detonator 10 (wireless Storage of the igniter can be done simultaneously and safely.

  In the crushing step K60, the operator operates the detonating operation device 50 to ignite the wireless detonating detonator to ignite the explosive (the parent die and the additional die), and executes the crushing of the portion to be crushed. Details of the processing procedure of the detonating operation device 50 at this time and the processing procedure of the wireless detonating detonator 10 will be described below.

● [Procedure for start-up controller 50 (wireless ignition controller) (Fig. 36)]
Next, with reference to a flowchart shown in FIG. 36, an example of the processing procedure of the start-up controller 50 (wireless ignition controller) will be described. The detonating operation device 50 (wireless ignition operating device) executes the wireless ignition operating device side program stored in the storage device 503 to execute the wireless shredding method based on the process of the flowchart shown in FIG. 36. . When the detonator 50 is activated by the worker, the process proceeds to step S10 shown in FIG.

  In step S10, the detonator 50 displays a process or the like on the display device 506, and the process proceeds to step S20. For example, as shown in FIG. 46, on the display device 506, a process display unit 506A, a crushed portion display unit 506B, and a setting information display unit 506C are displayed. For example, each step of “supply energy to wireless ignition tool”, “charge check”, “rewrite delay time”, “ignition standby”, “ignition count start”, “discontinue” is displayed on the process display unit 506A. Ru. For example, to-be-smashed part information Z20 shown in FIG. 41 is displayed on the to-be-smashed part display unit 506B, and, for example, setting information Z10 shown in FIG. 42 is displayed on the setting information display unit 506C.

[Crushed part information Z20 (FIG. 41) and setting information Z10 (FIG. 42)]
The crushing point information Z20 shown in FIG. 41 includes the entire outline of the crushing point of the crushing site, the position of each charge hole, the charge hole identification information for identifying the charge hole, and the crushing point. Area A1 within the first distance from the center, area A2 within the first distance from the first distance, area A3 within the second distance from the second, and area A4 within the fourth distance from the third Etc. are associated. For example, 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, the area (the area corresponding to the distance from the center of the portion to be crushed), the ignition delay time, the ignition tool identification information and the like are associated with the charge hole identification information. The ignition delay time is set to be longer as the distance from the central portion of the portion to be crushed to the charge hole is longer. 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 detonating operation device 50 wirelessly transmits the driving energy and the ignition energy of the electronic circuit 120 of the wireless detonating detonator 10 via the detonating operation device-side transmission antenna 60, and the process proceeds to step S110. . The driving energy and the ignition energy are continuously transmitted until the crushing process is completed or until interruption (the interruption will be described later). For example, when the operator supplies (by pressing) “supply energy to the wireless ignition tool” of the process display section 506A shown in FIG. Deliver energy wirelessly. The drive energy, the ignition energy, and the control signal described later are transmitted from the detonator 50 at an operation frequency of 100 kHz to 500 kHz, and transmitted at, for example, 200 kHz.

  For example, the charge operation (instruction) or the interruption is performed by blinking the “charge confirmation” and “discontinue” in the process display unit 506A shown in FIG. "Prompt" is displayed to prompt the operator to input, and the process proceeds to step S115.

  In step S115, the detonation operating device 50 determines whether or not the "disruptive instruction" is input. If the "disruptive instruction" is input (Yes), the process proceeds to step A, and the "disruptive instruction" is input. If not (No), the process proceeds to step S120.

  When the process proceeds to step A, the detonator 50 advances the process to step S525, and stores the global ID, the suspension instruction (suspension command), and the dummy data (00) in the control data in step S525. The process proceeds to step S530. In this case, the detonator 50 stores the global ID in the “ID” of the control data, stores the interruption instruction (disruption command) in the “command”, and stores dummy data (00) in the “data”.

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

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

  The checksum (CS) is one of so-called error detection codes, and in this case, a value obtained by adding each value stored in “ID”, “command”, and “data” is stored. The wireless detonating detonator 10 having received the control data (control signal) has a value obtained by adding the values stored in “ID”, “command”, and “data”, the value stored in “check sum”, and Can be determined by comparing them with each other by checking whether they match or not, it is possible to receive correct data without changing the data value due to noise or the like. Note that 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 detonator 50 calculates a checksum (CS) by adding each value of "global ID", "discontinue instruction", and dummy data (00) stored in the control data, and performs control. The control signal configured by data + CS is transmitted to the wireless detonator 10, and the process is ended.

  When the process proceeds to step S120, the detonation operating device 50 determines whether or not the "charge confirmation instruction" is input. If the "charge confirmation instruction" is input (Yes), the process proceeds to step S125. If the “charging confirmation instruction” has not been input (No), the process returns to step S110.

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

  In step S130, the detonator 50 calculates a checksum (CS) by adding the values of "global ID", "charge confirmation instruction" and dummy data (00) stored in the control data. The control signal configured by the control data + CS is transmitted toward the wireless detonating detonator 10, and the process proceeds to step S135.

  In step S135, the detonation operating device 50 determines whether or not the "disruptive instruction" is input. If the "disruptive instruction" is input (Yes), the process proceeds to step A, and the "disruptive instruction" is input. If not (No), the process proceeds to step S140. The process of step A is as described above, and thus the description thereof is omitted.

  When the process proceeds to step S140, the detonator 50 determines whether or not a predetermined time has elapsed since the transmission of the control signal in step S130, and if the predetermined time has elapsed (Yes), a timeout occurs. The process proceeds to step S160. If the predetermined time has not elapsed (No), the process proceeds to step S145.

  If the process proceeds to step S145, the detonator 50 determines whether a response signal from any of the wireless detonators 10 has been received, and if a response signal has been received (Yes), the process to step S150 If no response signal is received (No), the process returns to step S135.

  When the process proceeds to step S150, the detonating operation device 50 causes the charge state to be "operational state" included in the response signal, corresponding to the ID (ignition tool identification information) included in the response signal. Are 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 charge state included in the response signal is “charging completed”, the detonating operation device 50 corresponds to “ID (ignition implement identification information) included in the response signal” in the setting information. “Completed” is stored in the “charging state” field (see FIG. 43). In addition, when the state of charge included in the response signal is “under charging”, the detonating operation device 50 corresponds to “ID (ignition implement identification information) included in the response signal” in the setting information. “Charging” is stored in the “charging state” field (see FIG. 43).

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

  As shown in the example of FIG. 40, “ID” has its own ID, and the wireless detonating detonator stores the ignition tool identification information stored in itself in “ID” and transmits a response signal. Do. As for the "operation state", as shown in the example of FIG. 40, the "operation state" corresponding to the "disruption instruction" is "interruption complete", "interruption abnormality", and the "operation state" with respect to the "charge confirmation instruction". "Operation complete" and "Operation status" for "Delayed update completion" and "Operation status" for "Ignition standby instruction", which are "Operation status" for "Charge complete" and "during charging" There are "ignition standby OK" and "ignition standby abnormality". Further, as shown in the example of FIG. 40, “data” includes “ignition delay time” or dummy data (00).

  Checksum (CS) is one of so-called error detection codes, and in this case, a value obtained by adding each value stored in “ID”, “operating state”, and “data” is stored. The detonator 50 which has received the response data (response signal) adds a value obtained by adding the values stored in “ID”, “operating state”, and “data”, and the value stored in “check sum” , And it can be determined that the correct data has been received without the data value being changed due to noise or the like. Note that 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 detonating operation device 50 determines whether a response signal has been received from all the wireless detonating detonators 10 (all wireless ignition tools), and if it has received a response signal from all the detonating detonators 10 (Yes) The process proceeds to step S160, and if there is a wireless detonating detonator 10 that has not received a response signal (No), the process returns to step S135. For example, the detonator 50 may easily determine whether the response signal has been received from all the wireless detonators 10 based on the setting information stored in step S150 as "charging" or "done". it can.

  When the process proceeds to step S160, the detonator 50 determines whether the charge states of all the wireless detonating detonators 10 are all OK, and the charging states of all of the wireless detonating detonators are all OK ( Yes) advances the process to step S210, and advances the process to step B if at least one of the charge states is not OK or if there is a wireless detonating detonator that has not sent a response signal (No). For example, when all the fields of “(response) charge state” in the setting information shown in FIG. 43 are “completed”, the detonator 50 determines that the charge states of all the wireless detonating detonators are all OK. The process proceeds to step S210, and otherwise proceeds to step B.

  When the process proceeds to step B, the detonating operation machine 50 proceeds the process to step S510, and in step S510, for example, blinks "interruption" in the process display unit 506A shown in FIG. Then, the display is made to urge the operator to input an "interruption instruction", and the process proceeds to step S515.

  In step S515, the detonation operating device 50 determines whether or not the "disruptive instruction" is input. If the "disruptive instruction" is input (Yes), the process proceeds to step S525, and the "disruptive instruction" is input. If not (No), the process returns to step S510. The processes in steps S525 and S530 are as described above.

  When the process proceeds to step S210, the detonating operation device 50 blinks, for example, "rewrite delay time" and "discontinue" in the process display unit 506A shown in FIG. A display for prompting the operator to input "rewrite (instruction)" or "interrupt (instruction)" is displayed, and the process proceeds to step S215.

  In step S215, the detonation operating device 50 determines whether or not the "disruptive instruction" is input. If the "disruptive instruction" is input (Yes), the process proceeds to step A, and the "disruptive instruction" is input. If not (No), the process proceeds to step S220. The process of step A is as described above.

  When the process proceeds to step S220, the detonator 50 determines whether or not the "delay time rewriting instruction" is input. If the "delay time rewriting instruction" is input (Yes), the process proceeds to step S225. If the “delay time rewriting instruction” is not input (No), the process returns to step S210.

  When the process proceeds to step S225, the detonator 50 stores the individual ID, the delay time rewriting instruction (delay time rewriting command), and the ignition delay time in the control data, and the process proceeds to step S230. In this case, the detonator 50 stores a delay time rewriting instruction (delay time rewriting command) in the "command" of the control data. Then, based on the setting information shown in FIG. 43, the detonating operation device 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. The acquired ignition tool identification information is stored in "ID" of control data, and the extracted ignition delay time is stored in "data" of control data.

  In step S230, the detonator 50 calculates a checksum (CS) by adding each value of "individual ID", "delay time rewriting instruction" and ignition delay time stored in the control data, The control signal configured by the control data + CS is transmitted toward the wireless detonating detonator 10, and the process proceeds to step S235.

  In step S235, the detonation operating device 50 determines whether or not the "disruptive instruction" is input. If the "disruptive instruction" is input (Yes), the process proceeds to step A, and the "disruptive instruction" is input. If not (No), the process proceeds to step S240. The process of step A is as described above, and thus the description thereof is omitted.

  When the process proceeds to step S240, the detonator 50 determines whether or not a predetermined time has elapsed since the transmission of the control signal in step S230, and if the predetermined time has elapsed (Yes), a timeout occurs. The process proceeds to step S255 if it is determined that the predetermined time has not elapsed (No), the process proceeds to step S245.

  When the process proceeds to step S245, the detonator 50 determines whether or not the response signal from the wireless detonator 10 has been received. If 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 detonating operation device 50 causes the delay time to be the “operating state” included in the response signal in correspondence with the ID (ignition tool identification information) included in the response signal. The rewrite state is stored, and the process proceeds to step S255. For example, in the delay time rewriting state included in the response signal, as shown in FIG. 40, there are cases of “delayed rewriting completed” and “delayed rewriting failure”. For example, when the delay time rewriting state included in the response signal is “delayed rewriting completed”, the detonating operation device 50 corresponds to the ID (ignition tool identification information) included in the response signal in the setting information. “Normal” is stored in the “(response) delay state” column to be performed (see FIG. 44). In addition, when the delay time rewriting state included in the response signal is “delay rewriting failure”, the detonator 50 corresponds to the ID (ignition tool identification information) included in the response signal in the setting information. “Abnormal” is stored in the “(response) delay state” column to be performed (see FIG. 44). In addition, the detonator 50 is the ID (ignition tool identification information included in the response signal in the setting information) of the ignition delay time (the ignition delay time after the rewriting of the wireless detonating detonator) included in the response signal. Stored in the “(response) delay time” column corresponding to) (see FIG. 44).

  In step S255, the detonator 50 determines whether or not control data including a delay time rewriting instruction and an ignition delay time has been transmitted to the all-radio-excited detonators 10 in steps S225 and S230. For example, the detonating operation unit 50 sequentially performs steps S225 to S225 in order from the wireless detonating detonator corresponding to the ignition tool identification information on the top level in the setting information Z10B shown in FIG. 44 to the wireless detonating detonator corresponding to the ignition tool identification information on the lower level. If the process of step S250 is performed and control data including the delay time rewriting instruction and the ignition delay time are transmitted to all wireless detonating detonators (Yes), the process proceeds to step S260. If not (No), the process proceeds to step S225. The processing is returned, and control data including the next ignition tool identification information in the setting information is transmitted to the wireless detonation detonator corresponding to the ignition tool identification information.

  When the process proceeds to step S260, the detonator 50 determines whether the delay time rewriting state of all wireless detonating detonators 10 is all OK, and the delay time rewriting state of all wireless detonating detonators 10 If all are OK (Yes), the process proceeds to step S310, and even if at least one delay time rewriting state is not OK or there is a wireless detonating detonator that has not sent a response signal (No), the process proceeds to step B Proceed with the process. For example, when all the fields of “(response) delay state” in the setting information shown in FIG. 44 are “normal”, the detonating operation device 50 stores “(setting) ignition delay time” stored in advance; If the "(response) delay time" included in the response signal received from each wireless detonating detonator matches, it is determined that the delay time rewriting state of all wireless detonating detonators is all OK. The process proceeds to step S310, and if not, the process proceeds to step B. In addition, since the process of step B is as having mentioned above, description is abbreviate | omitted.

  When the process proceeds to step S310, the detonating operation unit 50 blinks “ignition standby” and “suspension” in the process display unit 506A shown in FIG. ) Is displayed to urge the operator to input “suspend” (instruction), and the process proceeds to step S315.

  In step S315, the detonation operating device 50 determines whether or not the "disruptive instruction" is input. If the "disruptive instruction" is input (Yes), the process proceeds to step A, and the "disruptive instruction" is input. If not (No), the process proceeds to step S320. The process of step A is as described above.

  If the process proceeds to step S320, the detonator 50 determines whether the "ignition standby instruction" is input. If the "ignition standby instruction" is input (Yes), the process proceeds to step S325. If the "ignition standby instruction" is not input (No), the process returns to step S310.

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

  In step S330, the detonator 50 calculates a checksum (CS) by adding each value of "individual ID", "ignition standby instruction" and dummy data (00) stored in the control data. The control signal configured by the control data + CS is transmitted toward the wireless detonating detonator 10, and the process proceeds to step S335.

  In step S335, the detonation operating device 50 determines whether or not the "disruptive instruction" is input. If the "disruptive instruction" is input (Yes), the process proceeds to step A, and the "disruptive instruction" is input. If not (No), the process proceeds to step S340. The process of step A is as described above, and thus the description thereof is omitted.

  When the process proceeds to step S340, the detonator 50 determines whether or not a predetermined time has elapsed since the transmission of the control signal in step S330, and if the predetermined time has elapsed (Yes), it indicates time-out. The process proceeds to step S355. If the predetermined time has not elapsed (No), the process proceeds to step S345.

  When the process proceeds to step S345, the detonator 50 determines whether or not the response signal from the wireless detonator 10 has been received, and if 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 detonating operation device 50 makes the ignition standby, which is the "operation state" included in the response signal, in association with the ID (ignition tool identification information) included in the response signal. The state is stored, and the process proceeds to step S355. For example, in the ignition standby state included in the response signal, as shown in FIG. 40, there are cases of “ignition standby OK” and “ignition standby abnormality”. For example, when the ignition standby state included in the response signal is “ignition standby OK”, the detonation operating device 50 corresponds to the ID (ignition implement identification information) included in the response signal in the setting information. Response: "Normal" is stored in the "standby state" column (see FIG. 45). In addition, when the ignition standby state included in the response signal is “ignition standby abnormality”, the detonator 50 corresponds to the ID (ignition implement identification information) included in the response signal in the setting information. Response: "abnormal" is stored in the "standby state" column (see FIG. 45).

  In step S355, the detonating operation device 50 determines whether control data including an ignition standby instruction has been transmitted to all the wireless detonating detonators 10 in steps S325 and S330. For example, from the wireless detonating detonator corresponding to the ignition tool identification information on the top level in the setting information Z10C shown in FIG. 45 to the wireless detonating detonator corresponding to the ignition tool identification information on the lower stage in order, the detonation operating unit 50 sequentially performs steps S325 to S325. If the process of step S350 is performed and control data including the ignition standby instruction is transmitted to all wireless detonating detonators (Yes), the process proceeds to step S360. If not (No), the process returns to step S325 and setting information The control data including the next ignition tool identification information in is transmitted toward the wireless detonating detonator corresponding to the ignition tool identification information.

  When the process proceeds to step S360, the detonator 50 determines whether the ignition standby state of all wireless detonating detonators 10 is all OK, and the ignition standby states of all wireless detonating detonators are all OK. If it is (Yes), the process proceeds to step S410, and if there is one even if the ignition standby state is not OK or there is a wireless detonating detonator that has not sent a response signal (No), the process proceeds to step B. For example, when all the columns of “(response) standby state” in the setting information shown in FIG. 45 are “normal”, the detonator 50 determines that the ignition standby states of all the wireless detonators are all OK. Then, the process proceeds to step S410, and if not, the process proceeds to step B. In addition, since the process of step B is as having mentioned above, description is abbreviate | omitted.

  When the process proceeds to step S410, the detonating operation device 50 blinks “start ignition count” and “discontinue” in the process display section 506A shown in FIG. A display for prompting the operator to input "instruction" or "interruption (instruction)" is displayed, and the process proceeds to step S415.

  In step S415, the detonation operating device 50 determines whether or not the "disruptive instruction" is input. If the "disruptive instruction" is input (Yes), the process proceeds to step A, and the "disruptive instruction" is input. If not (No), the process proceeds to step S420. The process of step A is as described above.

  When the process proceeds to step S420, the detonator 50 determines whether or not the "ignition count start instruction" has been input. If the "ignition count start instruction" is input (Yes), the process proceeds to 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 detonator 50 stores the global ID, the ignition count start instruction (an ignition count start command, corresponding to the ignition instruction or the ignition command) and dummy data (00) in the control data. Then, the process proceeds to step S430. In this case, the detonator 50 stores an ignition count start instruction (ignition count start command) in the "command" of the control data. Then, the detonator 50 stores the global ID in the “ID” of the control data, and stores the dummy data (00) in “data”.

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

  In the processes of steps S20, S125, and S130 described above, the driving energy and the ignition energy are directed to the respective wireless detonating detonators 10 (wireless ignition tools) by the detonator 50 (wireless ignition operating device). It corresponds to a state of charge request step of transmitting a control signal including a charge confirmation command (charge confirmation instruction) for requesting confirmation of the state of charge of ignition energy as well as delivering.

  Further, the processes in steps S150 and S160 described above are included in the received response signal when the detonator 50 (wireless ignition controller) receives each response signal including the ignition tool identification information and the charge state. In the charge state determination step, it is determined whether or not each wireless detonating detonator (wireless ignition tool) satisfies the charge state which is one of the predetermined conditions based on the ignition tool identification information and the charge state. Equivalent to.

  In addition, the processing of the above steps S225 and S230 is the ignition tool identification corresponding to the wireless detonating detonator (wireless ignition tool) determined to be satisfied by the detonation operating unit 50 (wireless ignition operating unit). 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 tool identification information, the extracted ignition delay time and the delay time rewriting command is It corresponds to the delay time rewriting request step of transmitting toward the wireless detonation detonator (wireless ignition tool).

  In addition, the processing in steps S250 and S260 described above is performed from the respective wireless detonating detonators 10 (wireless ignition devices) transmitted in the delay time rewriting response step by the detonation operating device 50 (wireless ignition type operating device). The response signal is received, and based on the ignition tool identification information and the ignition delay time included in the received response signal, the ignition delay time stored in each wireless detonating detonator 10 (wireless ignition tool) is grasped, It is determined whether 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 All the wireless detonating detonators 10 (wireless igniters) loaded in the charge hole are one of the predetermined conditions when all the associated igniter identification information and the ignition delay time coincide with each other. It determines that satisfies the condition rewriting manual delay time corresponding to the delay time rewrite state determining step.

  Further, in the process of steps S360 to S430 described above, all of the wireless detonating detonators 10 (wireless ignition devices) loaded in the charge hole in the detonating operation device 50 (wireless ignition operating devices) satisfy the predetermined conditions. If it is determined that the ignition instruction (the ignition count start instruction) is permitted, and the ignition instruction (the ignition count start instruction) is input while the input of the ignition instruction is permitted, the charge hole Sends a control signal including an ignition command (ignition count start command) to all the wireless detonating detonators 10 (wireless ignition devices) loaded in all the detonating detonators that are loaded in the charge hole. 10 (wireless ignition tool) corresponds to an ignition count start step that starts counting of elapsed time.

  Also, in the above steps S115, S135, S215, S235, S315, S335, S415, and S515 to S530, when the start instruction is input to the detonator 50 (the wireless ignition controller), the wireless detonator 10 It corresponds to the interruption request step of transmitting a control signal including an interruption command to the (wireless ignition tool).

  Further, the wireless ignition controller side program for executing the processing of the above steps S20, S130, S230, S330, S430, and S530 is the detonator 50 (the wireless ignition controller) for each wireless detonator 10 Control signal transmitting means 501A (FIG. 34) transmits a control energy including a command for instructing the wireless ignition detonator 10 (wireless ignition tool) while delivering driving energy and ignition energy to the wireless ignition tool). Function as reference).

  Further, the wireless ignition controller side program for executing the processing of the above steps S145, S245, and S345 is for each of the wireless detonating detonators which have received the control signal including the command from the detonator 50 (the wireless ignition controller). A response signal receiving unit 501B (see FIG. 34) which receives a response signal including the operating condition of the wireless detonating detonator 10 (wireless ignition tool) to the ignition tool identification information and the command from 10 (wireless ignition tool) is functioned.

  Further, the wireless ignition controller side program for executing the processing of the above steps S150, S160, S250, S260, S350 and S360 is included in the response signal received from the detonator 50 (wireless ignition controller). An ignition tool that determines whether or not each wireless detonating detonator 10 (wireless ignition tool) satisfies a predetermined condition based on the present ignition tool identification information, the operation state, and the stored setting information. It functions as the state determination unit 501C (see FIG. 34).

  Further, the wireless ignition controller side program for executing the processing of the above-mentioned steps S225 and S230 is based on the setting information, the ignition tool identification information, and the ignition tool identification device 50 (wireless ignition controller). A control signal including extracted ignition tool identification information, ignition delay time, and delay time rewriting command extracted from the ignition delay time associated with the identification information, each wireless detonating detonator 10 (wireless ignition tool) Function as a delay time rewriting request unit 501D (see FIG. 34).

  In addition, the wireless ignition controller side program that executes the processing of the above-mentioned steps S360 to S420 is all of the wireless detonator tubes 10 (the wireless ignition controller) loaded in the charge hole. When it is determined that the wireless ignition tool satisfies the predetermined condition, it functions as an ignition transmission permission unit 501E (see FIG. 34) that permits transmission of a control signal including an ignition command (ignition count start command).

  Further, the wireless ignition controller side program for executing the processing of the above-mentioned steps S420 to S430 transmits the control signal including the ignition command (ignition count start command) to the detonator 50 (wireless ignition controller). When an ignition instruction (ignition count start instruction) is input while permitting, all the wireless detonating detonators 10 (wireless communication) loaded with the control signal including the ignition command (ignition count start command) are loaded into the charge hole. Function as an ignition request transmission unit 501F (see FIG. 34) for transmission toward the ignition tool).

● [Process procedure of wireless detonating detonator 10 (wireless ignition tool) (Fig. 37)]
Next, with reference to the flowchart shown in FIG. 37, an example of the processing procedure of each wireless detonating gun tube 10 (wireless ignition tool) loaded in the charge hole will be described. The wireless detonating detonator 10 (wireless ignition tool) executes the wireless ignition tool side program stored in the storage unit to execute the wireless shredding method based on the process of the flowchart shown in FIG. Each wireless detonating detonator 10 loaded in the charge hole does not operate until the driving energy is supplied from the detonator 50, since it does not have a power source. When the driving energy is supplied wirelessly from the detonating operation unit 50, the wireless detonating detonator 10 proceeds to a process at step P10 shown in FIG.

  In step P10, the wireless detonating detonator 10 charges the drive energy supplied from the detonator 50, and performs the operations from step P20 onward with the charged drive energy.

  In step P20, the wireless detonating detonator 10 proceeds with the process to step P30 while charging the ignition energy supplied from the detonating operation device 50. In the case where the electronic circuit 120 charges the circuit which combines the ignition energy and the drive energy, the energy supplied wirelessly from the initiator 50 is charged as the drive energy and the ignition energy.

  In step P30, the wireless detonating detonator 10 determines whether or not a control signal is received from the detonator 50. If a control signal is received (Yes), the process proceeds to step P40 to receive the control signal. If not (No), the process returns to Step P20. When the value obtained by adding “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 or the like and can not receive the correct control signal, discards the received control signal, and returns the process to step P20.

  If the process proceeds to step P40, the wireless detonating arc tube 10 determines whether the command included in the received control signal is the “disruptive instruction”, and if the “disruptive instruction” is (Yes) The process proceeds to step P60, and when it is not the "interruption instruction" (No), the process proceeds to step P110.

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

  In step P70, the wireless detonation detonator 10 stores, in the response data, the ignition tool identification information stored therein, the interrupted state, and the dummy data (00), and the process proceeds to step P80. In this case, the wireless detonating detonator 10 stores the ignition tool identification information stored in the "ID" of the response data, and the "operation status" indicates "interruption complete" or "interruption abnormality" shown in FIG. Store the dummy data (00) in the "data". For example, if the processing at the time of interruption performed in step P60 can be normally executed, the wireless detonating detonator 10 stores “discontinuance completion” in the “state”, and some abnormality occurs and the processing at the time of interruption is normally performed. If it can not be executed, "interruption error" is stored in "operating status".

  In step P80, the wireless detonation detonator 10 calculates the checksum (CS) by adding the values of “ignition tool identification information”, “suspended state”, and dummy data (00) stored in the response data. The response signal configured by the response data + CS is transmitted to the detonator 50, and the process ends. In this case, since all wireless detonating detonators loaded in the charge hole transmit response signals, there is a possibility that interference will occur if the wireless detonating detonators transmit response signals wirelessly at the same time. Unfavorable because there is. Therefore, each wireless detonating detonator transmits a response signal when a response time (time from reception of a control signal to transmission of a response signal) has been uniquely set (time difference is sent) To do). For example, in each wireless detonating detonator, different response times are set for each wireless detonating detonator in association with the ignition tool identification information. The response signal is transmitted from the wireless detonator 10 at a response frequency of 100 MHz or more and 1 GHz or less, and is transmitted, for example, at 315 MHz or 429 MHz.

  When the process proceeds to Step P110, the wireless detonating detonator 10 determines whether the “command” included in the received control signal is the “charging confirmation instruction”, and is the “charging confirmation instruction”. (Yes) proceeds the process to step P120, and if it is not the “charging confirmation instruction” (No), the process proceeds to step P210.

  When the process proceeds to Step P120, the wireless detonating detonator 10 determines whether the “ID” included in the received control signal is a global ID, and if it is a global ID (Yes), the process proceeds to Step P160. If it is not a global ID (No), the process returns to step P20.

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

  In step P170, the wireless detonation detonator 10 stores, in the response data, the ignition tool identification information stored therein, the charge state, and the dummy data (00), and the process proceeds to step P180. In this case, the wireless detonating detonator 10 stores the ignition tool identification information stored in the "ID" of the response data, and "charging completed" or "charging" shown in FIG. Store the dummy data (00) in the "data". For example, when it is confirmed in step P160 that the wireless detonating detonator 10 has been charged to a predetermined amount of ignition energy, “charging completed” is stored in the “operation state”, and it is determined that the charging has not been performed to a predetermined amount When it is confirmed, "charging" is stored in the "operation state".

  In step P180, the wireless detonation detonator 10 calculates the checksum (CS) by adding the values of “ignition tool identification information”, “charging state” and dummy data (00) stored in the response data. The response signal composed of the response data + CS is transmitted to the detonator 50, and the process returns to Step P20. In this case, since all the wireless detonating detonators loaded in the charge hole transmit the response signal, as in step P80, each wireless detonating detonator receives its own set response time (control signal After that, when the time to transmit the response signal has elapsed, the response signal is transmitted (a time difference is sent). For example, in each wireless detonating detonator, different response times are set for each wireless detonating detonator in association with the ignition tool identification information.

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

  If the process proceeds to step P220, the wireless blast detonator 10 determines whether the “ID” included in the received control signal is not a global ID but an individual ID (igniter identification information), and the global If it is not an ID but an individual ID (Yes), the process proceeds to Step P230. If not (a global ID) (No), the process returns to Step P20.

  When the process proceeds to Step P230, the wireless detonating detonator 10 determines whether or not the ignition tool identification information stored in “ID” of the received control signal matches the ignition tool identification information stored in itself. If they match (Yes), the process proceeds to Step P260. If they do not match (No), the process returns to Step P20.

  When the process proceeds to step P260, the wireless detonation detonator 10 rewrites the ignition delay time stored in itself to the “ignition delay time” included in the received control signal, and stores the same in step P270. Proceed with the process.

  In step P270, the wireless detonation detonator 10 stores, in the response data, the ignition tool identification information stored therein, the delay state and the ignition delay time, and the process proceeds to step P280. In this case, the wireless detonating detonator 10 stores the ignition tool identification information stored in the “ID” of the response data, and “delayed rewriting completed” or “delayed writing” shown in FIG. The replacement failure is stored, and the "data" stores the ignition delay time read from its own storage means. For example, when the wireless detonation detonator 10 rewrites the ignition delay time in step P260, if the rewriting can be normally performed, “delayed rewriting completed” is stored in the “operation state”, and at the time of rewriting If an error occurs, "delayed rewrite failure" is stored in "operation status".

  In step P280, the wireless detonating detonator 10 calculates a checksum (CS) by adding the values of “ignition tool identification information”, “delay state”, and “ignition delay time” stored in the response data. The response signal composed of the response data + CS is transmitted to the detonator 50, and the process returns to Step P20. In this case, not all the wireless detonating detonators loaded in the charge hole transmit the response signal, but only one wireless detonating detonator whose ignition tool identification information matches, transmits the response signal, so interference is not generated. It does not occur. Therefore, when it becomes possible to transmit the response signal, it immediately transmits the response signal (sends without time difference).

  If the process proceeds to step P310, the wireless blast detonator 10 determines whether the "command" included in the received control signal is the "ignition standby instruction", and is the "ignition standby instruction" (Yes) proceeds the process to step P320, and if it is not the "ignition standby instruction" (No), the process proceeds to step P410.

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

  When the process proceeds to Step P330, the wireless detonating detonator 10 determines whether or not the ignition tool identification information stored in “ID” of the received control signal matches the ignition tool identification information stored in itself. If they match (Yes), the process proceeds to Step P360. If they do not match (No), the process returns to Step P20.

  If the process proceeds to step P360, the wireless blast detonator 10 executes the process in the ignition standby state, and proceeds to the process in step P370. In addition, description is abbreviate | omitted about the specific process as a process at the time of ignition waiting.

  In step P370, the wireless detonation detonator 10 stores, in the response data, the ignition tool identification information stored in itself, the standby state, and the dummy data (00), and the process proceeds to step P380. In this case, the wireless detonating detonator 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. Is stored, and dummy data (00) is stored in "data". For example, when the wireless detonating detonator 10 executes the processing in the ignition standby in step P360, stores “ignition standby OK” in the “operation state” if it can be normally executed, and if any abnormality occurs. Store “Ignition standby error” in “Operation status”.

  In step P380, the wireless detonating detonator 10 adds each value of “ignition tool identification information”, “standby state”, and “dummy data (00)” stored in the response data, and generates a checksum (CS). A response signal calculated and composed of response data + CS is sent to the detonator 50, and the process returns to Step P20. In this case, not all the wireless detonating detonators loaded in the charge hole transmit the response signal, but only one wireless detonating detonator whose ignition tool identification information matches, transmits the response signal, so interference is not generated. It does not occur. Therefore, when it becomes possible to transmit the response signal, it immediately transmits the response signal (sends without time difference).

  When the process proceeds to step P410, the wireless blast detonator 10 determines whether or not the "command" included in the received control signal is the "initiation count start instruction", and "in the ignition count start instruction" 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 wireless detonating detonator 10 determines whether the “ID” included in the received control signal is a global ID, and if it is a global ID (Yes), the process proceeds to Step P460. If it is not a global ID (No), the process returns to step P20.

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

  In step P470, the wireless blast detonator 10 determines whether the counted elapsed time has reached the stored ignition delay time, and if the elapsed time has reached 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 wireless detonating detonator 10 ignites using the charged energy for ignition.

  The process of the above steps P160 to P180 is one of the ignition tool identification information and the operation state in each wireless detonating detonator (wireless ignition tool) that has received the control signal including the charge confirmation command (charge confirmation instruction). It corresponds to the charge condition response step of transmitting a response signal including a certain charge condition to the detonator 50 (the wireless ignition controller).

  In addition, the processing of the above steps P220 to P280 is the wireless detonation detonator 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). And when the ignition tool identification information included in the received control signal matches the ignition tool identification information stored in itself, the ignition delay time included in the received control signal is stored, Corresponds to a delay time rewriting response step of transmitting a response signal including the stored (rewritten) ignition delay time and its own ignition tool identification information to the detonator 50 (wireless ignition controller). .

  Further, the processing of the above steps P40 to P80 corresponds to an interruption execution step in which the wireless detonation detonator 10 (wireless ignition tool) suspends itself when receiving a control signal including an interruption command.

  Further, in the processes of steps P80 and P180 described above, the wireless detonating detonators each have a response time which is the time from the reception of the control signal to the transmission of the response signal in each wireless detonating detonator 10 (wireless ignition tool). There is an interference avoidance step in which each 10 (wireless ignition tool) takes different times.

  Moreover, the wireless ignition tool side program for executing the processing of the above steps P60 to P80, P160 to P180, P260 to P280, and P360 to P380 is the wireless detonating detonator tube 10 (wireless ignition tool), the detonator 50 (wireless type). When a control signal including a command indicating an instruction to the wireless detonating detonator 10 (wireless ignition tool) is received from the ignition operating device), a response signal including the ignition tool identification information and its own operation state to the command is activated It is functioned as a response signal transmission unit 131A (see FIG. 27) that transmits toward the controller 50 (wireless ignition controller).

  In addition, the wireless ignition tool side program for executing the above steps P210 to P280 processes the wireless detonating detonator tube 10 (wireless ignition tool), the ignition tool identification information and the ignition delay from the detonating operation machine 50 (wireless ignition operating machine) When a control signal including a time and a delay time rewriting command is received, the ignition tool identification information included in the received control signal is stored if the ignition tool identification information stored by itself matches. It is functioned as a delay time rewriting execution unit 131B (see FIG. 27) that rewrites the present ignition delay time to the ignition delay time included in the received control signal.

  In addition, the wireless ignition tool side program for executing the above-described steps P410 to P480 performs an ignition command (ignition count start command) from the detonating operation device 50 (wireless ignition operating device) and the wireless detonation detonator tube 10 Delay ignition, which starts counting the elapsed time since the control signal is received, and fires when the elapsed time reaches the stored 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 the wireless shredding system 1 using the explosive unit 20 having the explosive 36 (parent die 36A, die increase 36B) has been described. In the second embodiment shown in FIG. 47 to FIG. 54, an example of a wireless shredding system 205 using a non-explosive unit 320 in which a non-explosive agent 201 is accommodated in a cartridge 202 will be described.

  In drilling tunnels and dismantling buildings, expectations for non-explosive blasting technology are rising due to the reduction of environmental impact and the drastic reduction of skilled blasting engineers. In response to such expectations for non-explosive blasting techniques, various non-explosive blasting techniques have been put to practical use in which the thermist surface of a tunnel excavated surface, concrete structure and the like is fractured by applying the thermit reaction. As this non-explosive blasting technology, there is one using high temperature and high pressure steam expansion pressure generated by the thermit reaction. For example, there is one marketed under the name of Gunsizer (Nippon Koki Co., Ltd., registered trademark), etc., and it is considered to be safer than gunpowder because it applies energy relatively slowly to the object to be crushed. ing.

  FIG. 47 shows an example in which the wireless shredding system 205 using the non-propellant unit 320 is applied to the excavation site of the tunnel, as compared with FIG.

The operation unit side reception antenna 65 includes the wireless ignition operation unit 250, the bus 262, the relay device 251, the auxiliary bus 261, the ignition operation unit side transmission antenna 260, the ignition operation unit side reception antenna cable 266, the ignition operation unit side reception Although the antenna 265 is substituted, since the appearance, the function, and the like are the same as each other, the description thereof will be omitted. In the example of FIG. 47, an example is shown in which the distance L1 is 0 [m].

  As shown in FIG. 48 and FIG. 49, the non-explosive agent unit 320 has a plastic cartridge 202 formed in a bottomed cylindrical shape closed at one end side, and a non-explosive agent 201 housed in the cartridge 202. And a wireless igniter 310 attached to the other end of the cartridge 202 and closing the other end. The wireless ignition tool 310 includes the ignition tool side reception antenna 311, the ignition tool side transmission antenna 318, the ignition unit 314, and the control unit 12, and is accommodated in the control case 162 and the protective case 165. Note that since the ignition tool side reception antenna 311 is the same as the initiation side reception antenna 11 and the ignition tool side transmission antenna 318 is the same as the initiation side transmission antenna 18, the description thereof will be omitted. Further, since the transmission auxiliary antenna 19 is the same, the description will be omitted.

  FIG. 48 shows an example in which one non-powder unit 320 is loaded in the charge hole 40, and FIG. 49 shows an example in the case where a plurality of non-powder units 320 are loaded in the charge hole 40. Each of the non-explosive units 320 has a cartridge 202 containing a non-explosive agent 201 and a wireless ignition device 310. And when loading a plurality of non-explosive units 320 in the charge hole 40, as shown in FIG. 49, the wireless ignition tool 310 is not connected to the wireless ignition tool 310 in the charge hole 40 without being connected to the ignition tool transmitting antenna 318.
