摘 要:针对长平矿五盘区煤层大巷过陷落柱区域变形严重的问题,通过地应力测试、围岩强度测试、围岩结构窥视掌握了巷道围岩地质力学参数,分析了煤层大巷变形原因,针对性地设计了五盘区胶轮车巷过DX176陷落柱支护方案。现场试验表明,试验巷道整体变形不大,锚索受力处于合理的范围之内,满足了煤层大巷的使用要求,经济效益显著。In view of the serious deformation problem of the coal seam main roadway passing through the collapse column area in the fifth panel area of Changping Mine,the geological and mechanical parameters of the roadway surrounding rock are mastered through ground stress testing,surrounding rock strength testing,and surrounding rock structure observation.The reasons for the deformation of the coal seam main roadway are analyzed,and a targeted support scheme for the rubber wheel truck roadway passing through the DX176 collapse column in the fifth panel area is designed.The on-site test shows that the overall deformation of the test roadway is not significant,and the anchor cable stress is within a reasonable range,meeting the requirements for the use of the coal seam main roadway,with significant economic benefits.
