Description

Technical Field

[0001] The utility model relates to the technical field of coal mine production, in particular to a coal mine peripheral safety protection device. Background Art

[0002] Coal-rich mining areas are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people generally choose to dig tunnels underground to mine coal. This is an underground coal mine. When the coal seam is very close to the surface, people generally choose to directly peel off the surface soil layer to excavate the coal. This is an open-pit coal mine. The vast majority of coal mines in my country are underground coal mines, and the scope of coal mines includes a large area of ​​the ground, underground and related facilities.

[0003] Some mines still fail to implement adequate safety measures in all aspects of actual work and fail to pay attention to every detail, but these negligence often lead to safety hazards.

[0004] In the process of mining, ground deformation often occurs. When personnel cannot discover the initial ground deformation in time, when it develops to the later stage, the ground deformation causes landslides and gravity imbalance, leading to safety accidents.

[0005] For this reason, we propose a coal mine perimeter safety protection device to solve the existing problems. Utility Model Content
