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, sur-rounding 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“first-driving-second-repairing” was changed.Field application effect was excellent.
