The guide wheels 115 and 122 are guided.

Next, the structure of the pneumatic pump unit 150 installed in the intermediate facility 2 and the conveying operation of the pneumatic carriage 110 will be described with reference to FIGS.
As shown in FIG. 26, in the pneumatic pump unit 150, a first discharge valve 153A is interposed in a first discharge pipe 152A connected from the discharge port of the pneumatic pump 151 to the auxiliary supply / exhaust pipe 19. Further, the first discharge pipe 152A on the inlet side of the first discharge valve 153A and the relay tunnel 15 on the inlet side of the relay position 20 are connected by the second discharge pipe 152B, and the first discharge pipe 152B is connected to the first discharge pipe 152B. A second discharge valve 153B is interposed on the pipe 152A side, and a third discharge valve 153C is interposed on the relay tunnel 15 side. A suction pipe 154 is connected between the intake port of the pneumatic pump 22 and the relay tunnel 15 on the outlet side of the relay position 20, and the first suction valve 155A is interposed in the suction pipe 154 on the pneumatic pump 22 side. In addition, a second suction valve 155B is interposed on the relay tunnel 15 side. Further, a first bypass pipe 156A having a bypass valve 157 is connected between the suction pipe 154 on the inlet side of the first suction valve 155A and the first discharge pipe 152A on the outlet side of the first discharge valve 153A. Furthermore, a second bypass pipe 156B is provided between the second discharge pipe 152B between the second discharge valve 153B and the third discharge valve 153C and the suction pipe 154 between the first suction valve 155A and the second suction valve 155B. It is connected. A circulation bypass pipe 158 is connected between the inlet of the circulation supply / exhaust passage 102 and the main supply / exhaust passage 13.

  In the above configuration, in the “underground feed process” in which the pneumatic carriage 110 is carried from the ground facility 8 to the intermediate facility 7 through the inclined shaft 12, as shown in FIG. 27, the second and third discharge valves 153B and 153C are bypassed. With the valve 157 closed, the first opening / closing device 21A opened, the second opening / closing device 21B closed, and the first discharge valve 153A, the first and second suction valves 155A, 155B closed, the air pump 151 Start. Then, when the pneumatic carriage 110 is introduced into the tilt shaft 12, the air in the downward direction is compressed and buffered and braked, and the forward air in the downward direction is supplied from the intermediate path tunnel through the suction pipe 154 to the pneumatic pump 151. And is discharged from the first discharge pipe 153A to the main supply / exhaust passage 13 via the auxiliary supply / exhaust pipe 19. Here, by adjusting the discharge flow rate of the pneumatic pump 151, the pneumatic carriage 110 lowers the inclined shaft 12 at an optimum speed to reach the relay position 20.

  Further, in the “disposal hole feed process” in which the air carriage 10 is transported from the relay position 20 to the disposal tunnel 2, as shown in FIG. 28, the main tunnel 1 is connected to the main tunnel 1 on the downstream side of the branch portion of the target disposal tunnel 1. A guide carriage 80 for closing the door and guiding the pneumatic carriage 10 to the disposal mine shaft 2 is disposed. In the disposal tunnel 2, the communication port 109 is opened at a position before the fixed position.

  Then, the first opening / closing device 21A is closed, the second opening / closing device 21B is opened, the first discharge valve 153A and the first and second suction valves 155A, 155B are closed, and the second and third discharge valves 153B, 153C are By opening the bypass valve 157 and starting the pneumatic pump 151, pressurized air is supplied from the discharge port of the pneumatic pump 150 to the inlet side of the relay position 20 through the second discharge pipe 152. The pneumatic carriage 110 is pushed by the pressurized air and moves in the main mine shaft 1, and is further sent to the target disposal mine shaft 2 by the guide trolley 80. At this time, the air in front of the air carriage 10 flows into the circulation exhaust passages 104 and 103 from the main tunnel 1 and the disposal tunnel 2 through the communication port 109. Further, it is discharged from the circulation bypass pipe 158 to the main supply / exhaust passage 13.

  When the pneumatic carriage 110 moves through the disposal tunnel 2 and passes through the communication port 109, as shown in FIGS. 32 (a) to 32 (c), the air in the buffer space 145 on the tip side from the communication port 109 becomes a buffer material, The pneumatic carriage 110 is decelerated and stopped. The air carriage 110 is moved to a predetermined stationary position by self-propelling, and after placing the waste body 100 in the concave groove 102, it is moved backward from the communication port 109 to the inlet side. At this time, every time the waste body 100 is placed in the concave groove 102 or each time a predetermined number of waste bodies 100 are placed in the concave groove 102, the dividing partition is separated by the communication port moving device 120 of the air carriage 110. The plate 107 is moved to the existing communication port 109 to be closed, and the removal space of the moved divided partition plate 107 is sequentially moved to the base end side as the communication port 109.

  Next, in the “disposal hole returning step” for returning the empty pneumatic carriage 110 to the relay position 20, as shown in FIG. 29, the first opening and closing device 21A is closed and the second opening and closing device 21B is left open. The third discharge valves 153B and 153C and the bypass valve 157 are closed, and the first discharge valve 153A, the first and second suction valves 155A and 155B are opened. Then, by starting the air pump 22, the air in the disposal tunnel 2 and the main tunnel 1 behind the air carriage 10 is sucked from the intake pipe 154, and the first discharge pipe 152A and the auxiliary supply are discharged from the discharge port of the air pump 22. The exhaust gas is discharged to the main supply / exhaust passage 13 through the exhaust pipe 19. The air in front of the air carriage 10 flows from the main supply / exhaust passage 13 through the circulation bypass pipe 158 into the circulation exhaust passage 103 and from the circulation exhaust passage 104 through the communication port 109 to the disposal tunnel 2 and the main tunnel. 1 to flow. Thereby, the pneumatic carriage 110 is made to reach the relay position 20 from the disposal tunnel 2 through the main tunnel 1. At this time, since the suction pipe 154 opens to the exit side (main mine shaft 1 side) of the relay position 20, the relay mine road 15 becomes a buffer space and is stopped near the relay position 20. When the stop position of the air carriage 110 is closer to the exit side, the second suction valve 155B is closed and the third discharge valve 153C is opened as shown in FIG. By sucking from the discharge pipe 152B to the pneumatic pump 151 via the second bypass pipe 156B and the suction pipe 154, the pneumatic carriage 110 can be moved to the inlet side. Or you may make it self-propelled.

  Here, the circulation exhaust passage 103 is opened to perform natural exhaust or natural supply. That is, the air in the rear of the pneumatic carriage 110 is forcibly pressurized or depressurized, and the air in the front of the pneumatic carriage 110 is naturally exhausted or supplied through the circulation exhaust passage 103 to advance the pneumatic carriage 110 forward. Move or move backwards. Here, when the air in the circulation exhaust passage 103 is forcibly supplied or forcibly exhausted, an opening / closing operation is performed at a branching portion of the circulation exhaust passage 102 integral with the main tunnel 1 and the circulation exhaust passage 103 integral with the disposal tunnel 2. An apparatus is required, and equipment cost will increase.

  Thereafter, when a predetermined number of waste bodies 100 are placed in the concave groove 103, the disposal tunnel 2 is moved to the front end by using a pump carriage (not shown) that can travel and move along the tunnels 1, 2, 12, and 15. Backfill sequentially from the side.

  Furthermore, in the “ground return step” for returning the empty air carriage 110 from the relay position 20 to the ground facility 8, as shown in FIG. 31, the first discharge valve 153A, the third discharge valve 153C, and the first suction valve 155A are moved. The second discharge valve 153B and the second suction valve 155B are closed, and the pneumatic pump 151 is activated. Thus, the air in the main supply / exhaust passage 13 is sucked from the sub supply / exhaust pipe 19 to the air feed pump 22 via the first bypass pipe 156A and the suction pipe 154, and the first and second discharges are made from the discharge port of the air feed pump 22. The pipes 152A and 152B and the second bypass pipe 156B are supplied to the exit side of the relay tunnel 15, and the pneumatic carriage 110 is moved up from the relay tunnel 15 along the inclined shaft 12 to reach the ground facility 8.

  According to the above-described embodiment, pressurized air is supplied and discharged from the pneumatic pump unit 150 to the inclined shaft 12 and the main supply / exhaust passage 13, and the pneumatic carriage 120 is reciprocated between the ground facility 8 and the intermediate facility 7. In addition, air is supplied to and discharged from the main tunnel 1, the target disposal tunnel 2, and the circulation supply / exhaust passages 103 and 104, and the air carriage 110 is reciprocated between the main tunnel 1 and the target disposal tunnel 2. Then, the waste body 100 can be carried from the ground facility 8 to the concave groove 102 of the disposal tunnel 2 via the relay facility 7. Therefore, even if it is a case where the waste body 100 is conveyed to the deep underground fixed disposal site 4, the waste body 100 can be conveyed and placed efficiently.

  In addition, air pressure is supplied to and discharged from the disposal tunnel 2 and the main tunnel 1, and circulation air supply and exhaust passages 103 and 104 formed integrally with the disposal tunnel 2 and the main tunnel 1 via a partition plate 105. Since 120 is moved forward and backward, the disposal tunnel 2 and the circulation supply / exhaust passage 104 can be sequentially backfilled after the waste body 5 is carried in. Thereby, the carrying-in operation | work and the backfilling operation | work of the waste body 100 can be implemented simultaneously, and the carrying-in of the waste body 5 in the underground facility disposal site 4, placement, and a backfill can be implemented efficiently. In addition, exhaust gas is not emitted like truck transport, unmanned transport is possible and work can be performed safely, and equipment costs and installation work costs are not increased like mechanical transport equipment. There is no cost increase.

  Moreover, since the main tunnel 1, the disposal tunnel 2, and the circulation supply / exhaust passages 103 and 104 are integrally formed in one passage by the partition plate 105, the number of tunnels and passages in the underground facility disposal site 4 can be halved. Construction cost can be greatly reduced. Moreover, it comprises the dividing partition plate 107 divided | segmented into the length direction, and the communication port 109 of the disposal mine channel 2 and the circulation supply / exhaust passage 104 is formed by deleting a part of the dividing partition plate 107, and the pneumatic carriage 110 By moving the dividing partition member 107 to the communication port 109 by the communication port moving device 120, the communication port 109 can be moved corresponding to the displacement of the stationary position, and the buffer space 145 can be formed. As a result, the disposal tunnel 2 and the circulation supply / exhaust passage 104 can be sequentially backfilled from the front end side, the disposal tunnel 2 can be formed and expanded, the waste 100 can be carried in, and the disposal tunnel 2 and the circulation supply / exhaust passage 104 can be filled. The returning operation can be performed at the same time, and the carrying of the waste body 100 at the underground facility disposal site 4, placement, and backfilling can be performed efficiently.

  Further, when the pneumatic carriage 110 is moved, the main pumpway 1, the disposal tunnel 2, and the relay tunnel 15 are forcibly supplied or exhausted by the pneumatic pump unit 150, and the circulation supply / exhaust passages 103 and 104 are made natural exhaust. Since the pneumatic carriage 110 is moved and moved by natural air supply, it is not necessary to switch the flow direction of the air by opening and closing the corresponding parts of the circulation passages 103 and 104 between the main tunnel 1 and the disposal tunnel 2. Thus, the facility can be simplified.
