摘要: 针对塔山煤矿8104工作面内错瓦斯高抽巷倾斜段穿层巷道在掘进期间围岩破坏严重的问题,研究分析了穿层巷道围岩破坏机理,提出了巷道锚注加固支护方案,经过理论研究和实践表明,在8103工作面跨采动压影响下,瓦斯高抽巷道穿层段顶底板相对移近量最大值为140.57mm,两帮相对移近量最大值为102.52mm,巷道严重变形情况得到有效控制,取得了显著的安全经济效益。

Abstract: In order to solve the Tashan mine 8104 working face in fault gas high pumping Lane inclined section of the wear layer of roadway, in neighboring 8103 working face mining in complex structure area excavated during the difficult to maintain and serious deformation. On the basis of studying the failure mechanism of the roadway, the paper puts forward the scheme of the bolt grouting support. Through theoretical research and practical application, it is indicated that the anchoring grouting supporting scheme not only keeps the stability of the tunnel in the layer, but also obtains the remarkable safety and economic benefits.
