Biaxially stretched plastic support net for underground coal mines

Product name: Biaxially stretched plastic mesh for underground coal mines Product introduction: Biaxially stretched plastic mesh false roof for underground coal mines uses the most advanced biaxially stretched geogrid equipment in the country, adding plastic particles with flame retardant and antistatic additives It is made through heating, extrusion, punching and stretching. It has excellent flame retardant and antistatic properties, referred to as double-resistance net. It is mainly used as a false roof and protective shield when mining thick coal seams underground in coal mines. It can also be used as an anchor. Support materials for pole tunnels, support tunnels, anchor-blasted tunnels and other tunnels are easier to construct and reduce production costs than metal mesh and hand-woven plastic mesh.
