| 摘 要： | 通过对平朔井工一矿9006辅运巷在4106工作面采动影响下发生的围岩变形进行观测与分析,掌握了巷道在采动影响下的变形情况。分析了两帮移近量、顶板下沉量和底鼓量的变化特征,揭示了测站变形量与工作面水平距离之间的定量关系,总结归纳了9006辅运巷变形经历的不同阶段,提出了在采动影响到达后加强巷道支护和加快工作面推进速度的建议,为今后4煤与9煤同采条件下安全回采提供了有力地支持。

| Abstract: | Roadway deformation influenced by mining was monitored in 9006 auxiliary roadway under 4106 mining face in 1st underground mine of Pingshuo Corporation.Convergence of two sides,values of roof subsidence and floor heave were analyzed,quantitative relationship between deformation value at the observation station and horizontal distance from mining face was discovered and different deformation phrases of 9006 auxiliary roadway were concluded.The suggestion that strengthening roadway supporting and increasing mining speed after mining influence reached was put forward which provided reference for simultaneously mining 4th coal and 9th coal. |
