摘　　要：在分析软岩巷道矿压特征及锚喷支护存在问题的基础上，提出喷层、锚杆支护和滞后注浆加固相联合的新型支护技术，采用动态施工控制技术维护巷道稳定。淮北矿务局芦岭矿松散破碎围岩条件下的采动影响巷道采用该项技术维护巷道取得了成功。A new support technology compounding bolt , shotcrete lining and delayed grouting is derived on the base of the analysis of ground pressure feature and the problem of bolt and shotcrete lining support. This method is a process of dynamic construction to control the stability of roadway and used successfully at the support of a mining affected roadway in unconsolidated and broken rock at Luling Colliery, Huaibei Mining Bureau.
