摘要
为控制巷道围岩变形,针对百良旭升煤矿515工作面皮带巷存在的围岩变形量大、锚杆断裂等支护失效问题,通过分析支护失效的主要原因,制定了针对性支护优化方案。现场实践结果表明,支护优化后的巷道围岩最大变形量54 mm,未出现锚杆断裂支护失效问题。
In order to control the surrounding rock deformation of roadway, aiming at the support failure problems such as large surrounding rock deformation and anchor bolt fracture in the 515 working face belt roadway in Bailiang Xusheng Coal Mine, by analyzing the main causes of support failure, a targeted support optimization scheme is made.The field practice results show that the maximum deformation of roadway surrounding rock after support optimization is 54 mm, and there is no failure of anchor bolt fracture support.
