摘　　要：在煤矿井下掘进工作面,由于矿工钢支护难度较大,支护成本较高,影响掘进工作面的施工进度,因此井下掘进巷道必须根据现场围岩情况进行支护方式合理变更。在围岩相对稳定、层节理较发育的地段,采用锚喷支护,加快了掘进进度,降低了支护成本费用,实现了一次成巷和安全生产。At the face underground tunneling in coal mines,the construction speed is influenced because the support with mine joist steel is difficult and the support cost is high.So the support way must be reasonably changed according to the host situation on-site.In the section with relative stabilizaiton in host and layer joinst more developmenet,the anchor shotcreting support is applied.The driving speed is rapid,the support cost is reduced,once roadway and safe production are realized.

关 键 词：锚喷支护 快速掘进 掘进工作面 围岩
