摘　　要：通过对滑动构造带大断面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,提出了对变形硐室采用壁后充填注浆,以及顶、帮、底板锚网索全封闭主动加固技术,充分改善围岩自身整体性及强度,巷道围岩变形得到有效控制,获得了较好的技术经济效果。According to the cause analysis of surrounding rock deformation of large-scale roadway in sliding structure belt,combined with roadway construction experience of other similar geological structure and deformation,the paper put forward back filling grouting in deformation chamber and full closed active reinforcement supporting technology of roof,rib spalling and floor cable anchor,which sufficiently improved the integrity and strength of surrounding rock itself, efficiently controlled roadway surrounding deformation and achieved good technical and economic effects.
