Improvement and Application of Anchoring Agent in Strong Water-containing Roof

Anchoring agent is widely used in coal mine roadway support. When there are a lot of water-containing roof, the performance and anchoring force of ordinary anchoring agent is reduced. For this reason, through the contrast test, NS-1 unsaturated polyester resin, XS-1 polymer instant powder, the powder and accelerator DMT and waterproof anchorage produced by mountain flour are used in a mine roadway support, the anchoring strength is able to meet the mine roof and floor anchoring force requirements. Anchoring force is enhanced, and the support effect is obvious.
