摘要
以红庆梁煤矿主斜井巷道松软岩泥化变形段为研究对象,通过现场围岩收敛变形监测,研究了围岩的失效机理,提出了采用注浆、超前小导管排桩、液压支架和锚索+槽钢联合锚网喷架4种支护方案,并通过加固前后围岩收敛变形量和变形速率,证实了锚索+槽钢联合锚网喷架支护形式的有效性,具有重要的工程实践意义。
Taking the roadway soft rock mud deformation section of Hongqingliang mining main shaft as the research object,through the conver-gence deformation monitoring of field surrounding rock,researched the failure mechanism of surrounding rock,put forward the grouting,advanced small pipe piles,hydraulic support and anchor cable = channel steel combined anchor mesh frame 4 support schemes,and through the before and after surrounding rock convergence deformation amount and deformation rate,confirmed the validity of anchor cable = channel steel com-bined anchor mesh frame support forms,had important practical significance.
