摘要
结合彬长矿区蒋家河煤矿软底巷道变形破坏特征,分析了巷道变形破坏原因,并提出了高强度支护方案;通过现场应用,表明高强度锚网支护能够有效控制巷道围岩破坏变形。
Based on the deformation and failure characteristics of soft floor roadways in Jiangjiahe Coal Mine in Binchang mining area,the reasons of roadway deformation and failure were analyzed and the high-strength support scheme was proposed. The field application shows that the high-strength bolt-net support can effectively control the failure and deformation of roadway surrounding rock.
