Description

Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to a support device for preventing collapse of filling material. Background Technology

[0002] The application of compression blasting in pillar mining is becoming increasingly mature. After the formation of the slotted space in the stope, the frequency of side collapse blasting can be increased as much as possible to maximize the amount of ore stored in the stope. The loose ore supports the walls of the adjacent stope filling body, reducing the exposed area of ​​the filling body and preventing the collapse and formation of large blocks. After each side collapse blast, ore should be loosened and extracted at the corresponding position at the bottom, while controlling the amount of ore extracted to ensure that the ore is loosened on the free face for the next blast, and so on in a cycle.

[0003] In the practical application of compression blasting, due to the failure of ore extraction to coordinate with mining, during large-scale mining, the ore extraction did not loosen the ore extraction path corresponding to each blasting area as required. This resulted in the ore on the free face of the next blast not meeting the loosening standard, which could easily lead to the collapse of the filling body, thereby blocking the internal mining space and affecting the subsequent mining progress.

[0004] Therefore, this utility model provides a support device for preventing the collapse of filling material. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a support device for preventing the collapse of filling material.

A first insertion hole is provided on one side of the rectangular plate, and a second insertion hole is provided on one side of the infill sidewall. A first insertion rod is inserted into the inner wall of the first insertion hole and the second insertion hole.

[0009] A support assembly is disposed at the bottom of a rectangular plate. The support assembly includes a U-shaped plate and a support mesh. The top of the U-shaped plate is fixedly connected to the bottom of the rectangular plate, and the top of the support mesh is disposed on the inner wall of the U-shaped plate.

[0010] The supporting components can protect the sidewalls of the filling material, preventing them from collapsing. The disassembly and assembly components can be used to install and fix the supporting components to the top of the ore body structure on the sidewalls of the filling material.

[0011] Optionally, an L-shaped plate is fixedly connected to the top of the rectangular plate, the top of the L-shaped plate is provided with a first screw hole, the top of the first insert rod is provided with a second screw hole, and the ore body portion at the top of the sidewall of the filler is provided with a third screw hole.

[0012] The first, second, and third screw holes can be aligned. Specifically, the first and second screw holes are drilled and aligned during the design process, while the second screw hole requires manual rotation of the first insertion hole to fix it with the first and third screw holes.

[0013] Optionally, the inner walls of the first screw hole, the second screw hole, and the third screw hole are threaded together with the same first threaded clamp.

[0014] The first threaded clamp can be fixed to the first threaded hole, the second threaded hole and the third threaded hole, thereby fixing the first insert rod and the side wall of the filler and other structures.

[0015] Optionally, a circular clamping cylinder is fixedly connected to one side of the rectangular plate, and a circular clamping rod is clamped to the inner wall of the circular clamping cylinder.

[0016] After the round clamping rod is inserted into the inner wall of the round clamping cylinder, it separates and supports the two rectangular plates, thereby improving the stability of the two rectangular plates.

[0017] Optionally, the two vertical plates of the U-shaped plate are provided with round insertion holes, and threaded rods are inserted into the inner walls of the round insertion holes and the inner walls of the mesh holes of the support net, with a fixing nut threaded to one end of the threaded rod.

[0018] Under the action of the threaded insert rod, it cooperates with the round insert hole and the mesh of the support mesh to fix the support mesh inside the U-shaped plate.

[0019] Optionally, a plurality of third insertion holes are provided on one side of the sidewall of the filler, and a second insertion rod is inserted into the inner wall of the third insertion hole and the inner wall of the mesh of the support net, and a circular baffle is fixedly connected to one end of the second insertion rod.

[0020] The second insertion rod, in conjunction with the third insertion hole and the mesh of the support mesh, thereby fixing the support mesh to the side wall of the filler.

[0021] Optionally, a rectangular connecting block is fixedly connected to the outer surface of the circular baffle. A fourth screw hole is provided on one side of the rectangular connecting block, and a fifth screw hole is provided on one side of the sidewall of the filler. A second threaded clamp is threadedly connected to the inner walls of the fourth and fifth screw holes.

[0022] The second threaded clamp, in conjunction with the fourth and fifth threaded holes, is used to fix the rectangular connecting block and the side wall of the filler. At this time, the second threaded clamp needs to penetrate the inner wall of the mesh of the support mesh when fixing.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0024] By installing support components, a support net can be used to support the sidewalls of the infill material, preventing large-scale collapse. Simultaneously, the support net is fixed to the sidewalls using multiple second rods and other components, allowing it to absorb stress and prevent further collapse in the event of localized sidewall collapse. Furthermore, by installing assembly and disassembly components, rectangular plates can be used to fix the top of the support net to the top of the ore body structure on the sidewalls of the infill material. This further limits and secures the support net, preventing direct separation during large-scale sidewall collapses and providing temporary support. Attached Figure Description
