强含水顶板锚固剂的改进与应用

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

摘要: 锚固剂被广泛应用在煤矿井巷的支护中，但当煤巷中存在大量含水岩层时，普通锚固剂的性能降低，锚固力下降。为此，通过试验对比，选用NS-1不饱和聚酯树脂、XS-1高分子速溶胶粉、促进剂DMT和石粉生产的防水型锚固剂应用于某矿井的多条含水层的巷道支护中，能够满足矿井顶、底板锚固力的要求，锚固力增强，支护效果明显。

Abstract: 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.
