铺龙湾矿综采工作面巷道围岩控制及数值模拟分析

Surrounding Rock Control and Numerical Simulation Analysis of Roadway in Fully Mechanized mining face of Pulongwan Mine

为保证工作面巷道围岩的稳定,针对8106工作面回采巷道支护上存在的问题及巷道失稳原因,对回采巷道支护进行优化。在81021掘进工作面巷道选用优化后的支护材质及支护方式,对原有8106工作面回采巷道进行数值模拟分析,比较两者之间的围岩应力,表明优化后的方案极其有效,为类似条件下巷道围岩支护提供了成功案例。

In order to ensure the stability of the surrounding rock of the working face roadway,the support of the mining roadway in 8106 working face was optimized in response to the problems and reasons for the instability of the roadway.The optimized support materials and methods were selected for the 81021 excavation face roadway,and numerical simulation analysis was conducted on the original 8106 mining face roadway.The comparison of the surrounding rock stress between the two showed that the optimized plan was extremely effective,providing a successful case for the surrounding rock support of the roadway under similar conditions.
