FIG. 5 is an explanatory view showing a state in which the packaging explosive and the contents are held in the loading hose of the loading device. FIG. 6 is a view showing an example of a loading machine mounting jig, where (a) is a front view thereof and (b) is a side view thereof. FIG. 7 is an operation diagram showing an operating state of the loading machine attached to the loading machine attachment jig.

  As shown in FIG. 1, a plurality of charge holes 14 are formed at a predetermined depth in the upper and lower portions of the face surface 13 of the tunnel 12 formed in the rock mass 11. A drill jumbo 15 for excavating the tunnel 12 is disposed in the tunnel 12. At the tip of the boom 16 of the drill jumbo 15, a basket 18 is loaded for the loading operator 17 to perform a loading operation for loading the explosive into the charge hole 14.

  The explosive loading device 20 in this embodiment includes a loading machine 21, a loading hose 22 connected to the loading machine 21, and a loading pipe 23 connected to the loading hose 22. The loader 21 is attached to the basket 18 of the drill jumbo 15 using a loader attachment jig 24. A loading hose 22 is detachably coupled to the other end of the loading machine 21, and a loading pipe 23 is connected to the tip of the loading hose 22. The loading hose 22 is supported so as not to get entangled when the loading hose 22 is swung around the hose support member 25 or guide roller of the basket 18 in the middle of the loading hose 22, but it is not always necessary to support them. In this example, the loading pipe 23 is inserted into one of a plurality of charge holes 14 drilled in the upper part of the face surface 13 in the rock mass 11.

  An example using a guide roller is shown in FIG. In this case, the loading hose 22 connected to the loading machine 21 extends between the pair of upper and lower guide rollers 60 provided at the upper end of the basket 18 in the direction of the charge hole 14. Then, after the loading operator 17 loads the explosive 45 from the loading port of the loading machine 21 and once holds the explosive 45 in the loading hose 22, the explosive 45 is charged without being clogged in the loading hose 22 by the pressure feeding means. The hole 14 is easily loaded.

  Although the loading machine 21 is disposed within the operation range of the loading operator 17, in this embodiment, the loading machine 21 is used by being attached to the frame 26 of the basket 18 as described later. It means within the range that can be used by being attached to the frame 26 of the basket 18. Moreover, the loading machine 21 has portability and can be easily carried by the loading operator 17. The loading machine 21 is mounted on the frame 26 of the basket 18 and is loaded with the explosive 45.

  When loading the explosive 45 into the charge hole 14 drilled in the lower part of the face 13, the loading machine 21 is not fixed to the basket 18 of the drill jumbo 15 as shown by the two-dot chain line in FIG. 1. A method can also be taken. That is, the loading machine 21 can be supported within the operation range of the loading operator 17 by using a support 28 made of, for example, a tripod on the ground 27.

  The drill jumbo 15 is provided with, for example, an air compressor (air compressor) 29 as pressure feeding means and a water supply device 30 as water supply means as existing underground facilities. The air compressor 29 constitutes a pressure feeding means, one end of an air supply pipe 31 for sending compressed air is connected, and the other end is connected to the loading machine 21 via a distributor 32. Further, one end of a water supply pipe 33 constituting a water supply means is connected to the water supply device 30, and the other end is connected to the loading machine 21 via a distributor 32. The distributor 32 is used for simultaneously loading the explosive 45 and the contents into the plurality of charge holes 14 using the plurality of loading devices 20. In addition, the control apparatus 52 is provided in the middle of the air supply pipe | tube 31 and the water supply pipe | tube 33, and adjusts an air pressure and water quantity to an appropriate value.

Next, an example of the loading machine 21 used here will be described in detail with reference to FIGS.
The loading machine 21 includes a substantially cylindrical housing 34. The housing 34 has a loading port 35 at one end and a cylindrical portion 36 at the other end. The insertion port 35 has a trumpet shape that spreads toward the end face in order to make it easier to insert the explosive 45 and the contents, but it is not always necessary to have this shape. Any shape can be used as long as it is easy to throw in. The cylindrical portion 36 may have any shape as long as the packaging explosive can pass through it, but for example, if a cylindrical body having a rotation mechanism such as the swivel joint 61 shown in FIG. 9 is used, the twist of the loading hose 22 is corrected. This is preferable in terms of operation. That is, the cylindrical portion 36 is fitted in the fitting hole 62 of the swivel joint 61 and is configured to be rotatable by the ball bearing 63.

  As shown in FIGS. 2 to 4, a coupler 38 is attached to the housing 34 via a coupling means for communicating the air supply pipe 31 and the inside of the housing 34, for example, a ball valve 37. The air supply pipe 31 is detachable. In this case, the ball valve 37 is not always necessary from the viewpoint of operability. The air supply pipe 31 is formed by a pressure-resistant hose, and is provided with an air operation valve incorporated in the control device 52 and a switch (not shown) for operating the air operation valve. And if the said switch is operated by the loading operator 17, an air operation valve will be opened and closed by the air pressure of the existing mine installation (pilot line). As a result, the loading operator 17 can perform an operation at a location away from the loading machine 21.

  A loading valve 39 is provided in the housing 34 of the loading machine 21 at a position near the inside of the loading port 35. The charging valve 39 is, for example, a spring type, and the loading machine 21 is arranged so that the charging port 35 is above the cylindrical portion 36, in this case, substantially above as shown in FIG. Yes. When an explosive 45 such as a packaging explosive 45 is introduced from the introduction port 35, the introduction valve 39 is pushed and opened due to the drop of the explosive 45 (the state of the two-dot chain line in FIG. 2). It is a form that returns and closes, that is, a form that is closed when compressed air is fed.

  The housing 34 is preferably supplied with water in order to prevent the explosive 45 from being clogged in the loading hose 22 when the explosive 45 is pumped. The water supply means is provided for this purpose. In this example, a coupler 38 is attached via a ball valve 37 similar to the pressure feeding means, and the end of the water supply pipe 33 is detachable. Also in this case, the ball valve 37 is not necessarily required due to the presence of a switch (not shown) that opens and closes the water supply operation valve incorporated in the control device 52 as in the case of the air supply pipe 31. Further, when the counter 40 is provided in the housing 34, the number of passages of the explosive 45 is counted (counted) by interlocking, for example, a spring-type protrusion protruding into the housing 34 with the counter. Can do. In order to handle the explosive 45, the counter 40 is not provided with an electrical element. However, when it is provided, it is necessary to use it with careful handling.

  A cylindrical portion 36 is provided at the other end of the housing 34, and the other end of the cylindrical portion 36 is attachable to and detachable from the plug 43 of the loading hose 22 by a coupling means, for example, a socket 42 of a lever lock coupler 41. It is connected. Further, a handle 44 for facilitating the transport of the loading machine 21 is attached to the cylindrical portion 36. The weight of the loading machine 21 itself is, for example, about 5 kg, the length is about 60 cm, and it is lightweight.

Next, the explosive 45 used in this embodiment is a granular explosive such as ANFO, a hydrous explosive, or the like, and preferably a hydrous explosive. The explosive 45 packaged with paper or a plastic film, that is, a package explosive is used from the viewpoint of handleability. The package explosive has an outer diameter of generally 25 to 30 mm and a length of about 100 to 250 mm. In addition, the inclusions made of clay, for example, are approximately the same size. What is necessary is just to change the magnitude | size of the said loading machine 21 suitably according to the magnitude | size of packaging explosives or a container. Therefore, in the present embodiment, the inner diameters of the housing 34, the cylindrical portion 36, the loading hose 22 and the loading pipe 23 are slightly larger than the outer diameters of the packaging explosives and contents, and are set to 30 mm or so, for example.

Next, the loading hose 22 connected to the loading machine 21 is formed in a cylindrical shape, and the length thereof is about 5 m and is set short. The material of the loading hose 22 can withstand air pressure as a pressure feeding means, for example, about 0.3 MPa (3 kgf / cm ² ), and does not clog packaging explosives, for example, the bending radius of the loading hose 22 is 500 mm, Preferably, it has a strength that does not become smaller than 600 mm, more preferably 750 mm. For example, a resin hose reinforced with metal or the like is used as the loading hose 22. Then, as shown in FIG. 5, the explosive 45 loaded in the loading machine 21 is temporarily held (stocked) in the loading hose 22, and then the contents 46 loaded in the loading machine 21 are loaded into the loading hose 22. It is once held in the.

  Unlike the loading hose 22, the loading pipe 23 connected to the tip of the loading hose 22 is a distance that does not affect the loading operator 17 even if the rock mass 11 collapses, for example, a face surface separated by about 2 to 3 m. It is inserted directly into the 13 charge holes 14 via the loading hose 22. For this reason, the loading pipe 23 is a lightweight and highly rigid pipe. If the loading pipe 23 is transparent, it is better because the inside can be confirmed. As the material of the loading pipe 23, for example, glass fiber reinforced plastic (GFRP) is adopted. In addition, since the loading pipe 23 is directly inserted into the charging hole 14, it is preferable that the surface of the GFRP is wound with, for example, a carbon tape to prevent charging, and an FRP containing carbon fibers may be used. The length of the loading pipe 23 is, for example, about 2.5 m, and the weight is as light as about 600 g.

Next, a method of fixing the loading machine 21 on the basket 18 will be described with reference to FIGS.
As shown in FIG. 6, the loading machine 21 is rotatably mounted by a loading machine mounting jig 24. The loader mounting jig 24 is attached to the frame body 26 of the basket 18 by an upper clamp 47 and a lower clamp 48. An attachment adjusting portion 49 is provided so as to be attachable to various baskets 18 and can be expanded and contracted by, for example, about 20 cm in the length direction. Although the loading / unloading jig 24 can be easily attached / detached, it does not interfere with other operations during the construction period, and is thus held attached to the basket 18 during that period. The loading machine 21 can be attached to the loading machine mounting jig 24 by a method in which the protruding portion 51 of the loading machine 21 is fitted into the mounting hole 50 of the loading machine mounting jig 24 or can be attached and detached by one touch different from this. May be possible. For example, a one-touch attachment / detachment jig is shown in FIGS. That is, the loading machine mounting jig 24 is formed with a pair of upper and lower keyhole-shaped engaging holes 64, and an engaging long hole 65 is formed in communication with the lower part of the circular hole constituting the engaging hole 64. ing. On the other hand, a mounting plate 66 is provided at the tip of the mounting shaft portion 68 of the loading machine 21, and an engaging hook 67 having a lateral L-shape is protruded from the vertical position of the mounting plate 66. Then, after inserting the hook 67 of the loading machine 21 into the engagement hole 64 of the loading machine mounting jig 24, the hook 67 is engaged with the portion of the long hole 65 by lowering so that the loading machine 21 does not fall off. Can be. Furthermore, by providing a rotation mechanism to the attachment shaft portion 68, the operability can be further improved. When removing the loading machine 21 from the loading machine mounting jig 24, the loading machine 21 is lifted, the hook 67 is moved upward, and is extracted from the engagement hole 64. In addition, the loading machine 21 shown by FIG.10 (b) has shown only the housing 34 and the insertion port 35 of the loading machine 21 shown by FIG.

  In the fitting method, as shown in FIG. 7, the loading machine 21 is rotatable at the protruding portion 51 or the mounting shaft portion 68, and is supported so that the charging port 35 is substantially directly above when the explosive 45 is charged. When the explosive 45 is charged into the charge hole 14, for example, the charge hose 22 is configured to be easy to handle by rotating to an angle indicated by a two-dot chain line. In other words, it is preferable that the loading machine 21 is arranged so that the loading port 35 is almost directly above when the explosive 45 is charged, and is rotated at an appropriate angle, for example, 45 degrees at other times. It is preferable.

Next, a method for loading the explosive 45 using the loading device 20 will be described.
As shown in FIG. 1, the boom 16 of the drill jumbo 15 is expanded and contracted so that the basket 18 is positioned about 2 m before the face surface 13 and is moved up and down and left and right. Subsequently, the loading worker 17 on the basket 18 charges the detonation explosive (parent die) to which the detonator is attached into the charging hole 14. The charge of the parent die may be manually loaded by a normal loading rod. Alternatively, the parent die is attached to the tip of the loading pipe 23, the loading pipe 23 is inserted into the charging hole 14, and the compressed air is blown. Thus, the parent die can be charged at the bottom of the charging hole 14. Next, the loading operator 17 on the basket 18 inserts the loading pipe 23 into the charge hole 14 where the explosive 45 is scheduled to be loaded. Next, when the loading operator 17 loads the explosive 45 into the loading port 35 of the loading machine 21 attached to the basket 18, the water supply ball valve 37 of the loading machine 21 is opened or the water is automatically supplied by a switch operation. The water supply operation valve is opened to spray a predetermined amount of water into the loading machine 21. Thereafter, a predetermined number of, for example, three explosives 45 are introduced into the inlet 35, and it is confirmed by the counter 40 whether or not all of the three explosives 45 have been introduced.

  Next, for example, three containers 46 are put into the inlet 35 in the same manner. As shown in FIG. 5, the charged explosive 45 and the filling 46 are temporarily held inside the loading hose 22. Here, since the loading hose 22 is made of a material in which the resin hose is reinforced with metal or the like, the loading hose 22 is not clogged with a curved portion formed by holding the explosive 45.

  Thereafter, the air-operated valve is opened by operating the switch, and the explosive 45 and the filling 46 are loaded into the charge hole 14 from the loading pipe 23. After loading, the loading operation to one charging hole 14 is completed by pulling out the loading pipe 23 from the charging hole 14. Further, the same operation can be sequentially performed on the plurality of charging holes 14 or simultaneously loaded on the plurality of charging holes 14 using the plurality of loading devices 20 via the distributor 32.

  When the explosive 45 to be loaded is an ANFO explosive, the ANFO itself lacks water resistance, so water supply by the water supply device 30 and the water supply pipe 33 is not performed. In addition, loading of the explosive 45 from the loading port 35 of the loading machine 21 is performed, for example, by loading the explosive 45 weighed in advance.

  As is clear from the above description, according to the loading method of the explosive 45 of the present embodiment, since the loading hose 22 is short, the loading workability can be dramatically improved. In addition, the air pressure as the pressure feeding means can be set lower than before, the influence on the packaging explosive is small, and it does not become an overload, so that the handling of loading can be improved. The loading machine 21 used in such a loading method has a simple configuration and can temporarily hold the explosive 45 or the like in the loading hose 22, so that a conventional hopper or the like is not required, and thus the size and weight are reduced. be able to.

The effects exhibited by the above embodiment will be described collectively below.
In the explosive loading method of the present embodiment, the loading machine 21 is disposed within the operation range of the loading operator 17, and the explosive 45 is inserted from the loading opening 35 so that the loading opening 35 is above the cylindrical portion 36. The explosive 45 is once held in the loading hose 22, and then the explosive 45 is loaded into the charge hole 14 through the loading pipe 23 by the pressure feeding means.
