摘　　要：采用理论分析和室内实验对某深埋盘区大巷围岩的破坏机理进行了分析,得到了大巷围岩破坏的原因。结合大巷围岩松动圈测试结果,探讨了原有支护方案的不足,并针对性地提出了大巷修复方案。运用数值模拟计算对所提的大巷修复方案的合理性进行了验证。结果表明,提出的巷道修复方案合理有效,能够抑制大巷的变形,满足运输大巷的变形要求。Based on theoretical analysis and laboratory experiments analyses the failure mechanism and supporting technology of surrounding rock in deep buried roadway, and get the causes of the surrounding rock damage. Combined with the results of the surrounding rock loose circle test,discusses the shortcomings of the original support scheme, and gives the repairing scheme of the main roadway.Using numerical simulation to validate the rationality of the repairing scheme, the results show that the repairing scheme is reasonable and effective which not only can restrain the deformation, but also can meet the requirement of the deformation of the roadway.
