Description

Technical Field

[0001] The utility model relates to the technical field of baffles for filling and plugging coal mines, in particular to a new baffle for filling and plugging coal mines. Background Art

[0002] Coal mines can generally be divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal, which is an underground coal mine; when the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal, which is an open-pit coal mine. Most of my country's coal mines are underground coal mines. When mining in underground coal mines, backfilling must be used, that is, the mining area needs to be backfilled after coal mining. Backfilling can solve the problems of gangue accumulation in mining areas and reduce surface subsidence. During the mining process, construction personnel can use the backfilling and plugging device to replace this part of the coal, which can extend the service life of such mines, improve resource recovery rate, and deal with waste such as gangue generated by mining, effectively protecting the environment. The commonly used backfilling device is to use a fixed plugging bracket to plug the paste or block. Before and after plugging, the plugging bracket needs to be manually transported, which wastes a lot of manpower and material resources and affects the filling efficiency.

[0003] Therefore, it is necessary to propose a technology to improve the above defects. Utility Model Content
