Description

Technical Field

[0001] The present invention belongs to the technical field of coal mine tunnel support, and more specifically, particularly relates to an impact-resistant support structure for a coal mine tunnel. Background Art

[0002] 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 peel off the surface soil layer to mine coal, which is an open-pit coal mine; the tunnels in underground coal mines require tunnel support structures to keep the tunnels unobstructed and the surrounding rock stable.

[0003] The coal mine tunnel support structures currently in use still have the following problems: 1. Poor impact resistance. When the tunnel is affected by impact ground pressure, the support structure is easily damaged after the impact, affecting the supporting effect of the support structure; 2. It is impossible to fix the support structure in different directions during installation, which increases the difficulty of installing the support structure; 3. When the support structure is subjected to impact force, it cannot automatically alert the workers in the coal mine tunnel, increasing the safety hazards of the workers in the coal mine tunnel.
