摘　　要：针对深部矿井岩石巷道围岩整体变形量大、持续时间长、局部破坏严重的支护难题,以朱集矿-965东翼轨道大巷为工程背景,在进行系统地质力学测试、围岩变形破坏特征分析、支护形式选取与现场试验的基础上,对深部高地应力复合岩层巷道围岩控制技术进行研究。通过优化锚杆支护参数、合理选择护表形式与构件,实现了深部复合岩层巷道围岩的一次主动支护,有效控制了深部巷道围岩的长期持续变形,改变了深部岩巷"前掘后修、反复维修"的局面,取得了良好的现场应用效果。In order to solve the supporting problem of large and long-time deformation,local serious failure in deep rock roadway,surrounding rock control technology was researched on the basis of testing geo-stress,analyzing failure characteristic of surrounding rock,selecting supporting manner and field test. By operating anchored bolt parameters,rationally selecting supporting components,one-time initiative supporting of deep roadway with composite rock was realized and long-time deformation was controlled. The situation of＂firstdriving-second-repairing＂ was changed. Field application effect was excellent.
