摘要
为解决清水营煤矿"三软"煤层110202工作面辅运巷难以支护的问题,通过分析工作面巷道来压情况和巷道破坏的主要因素,认为围岩工程力学性质差和支护与围岩不适应是导致工作面巷道严重破坏的主要原因。根据巷道支护与围岩的耦合性原理,应用理论计算和FLAC3D数值模拟方法,设计了锚网索+钢支架联合支护的综合治理方案。
In order to solve the serious floor heave problem of face 110202 Qingshuiying coal mine,by analyzing the main factors of roadway strata behavior and damage of face 110202,the main reason leading to serious damage of mining roadway lays in the poor surrounding rock engineering mechanics properties and the uncoupling between the support and surrounding rock. According to the coupling principle between the support and surrounding rock, through theoretical calculation and FLAC3 D numerical simulation methods, a comprehensive treatment scheme with cable anchor and steel frame is designed.
