Welded Coal Mine Supporting Mesh Guard Coal Mine Roadway Safety

Welded coal mine supporting mesh is made by welding steel wires together to form a grid-like pattern. This mesh retains the walls against falling rocks and ensures the safety of the miners during drilling, and also protects them from loose scaling in the mines. Flush cut edges improve handling, installation, and maintenance of safety standards. The service life is extended due to the anti-corrosion properties. It can perform well in the safety protection of coal mine roadway, tunnels and other facilities.

A drilling machine is working in the coal mine site and the tunnel is protected by the welded mesh supporting mesh.
