摘　　要：通过对滑动构造带巷道围岩变形原因分析,结合矿井其它类似地质构造、变形等巷道的施工经验,提出采用锚网、锚索等主动支护的同时增加36U刚性棚支架联合支护,再加上围岩注浆加固,充分改善围岩自身整体性及强度。通过采用主被动支护技术后,巷道围岩变形得到了有效控制,达到了预期支护目的,同时降低了巷道的支护成本,经济效益显著。On the cause analysis of the surrounding rock deformation in slip structure zone, in combination of construction experience of other roadways with similar geological structure and deformation,the author proposed an integrated support with mesh, anchor cable, and other active supporting methods as well as 36U-type shed. In addition, grouting reinforcement was adopted to improve integrality and strength of the surrounding rock. The active and passive supporting technology could effectively control the deformation and achieve the expected supporting goal. Meanwhile, the supporting cost was reduced to obtain obvious economic benefits.
