摘　　要：为解决受叠加应力影响造成的盘区大巷底鼓、煤柱破坏等巷道失稳问题,通过现场调研、理论分析等方法分析了大巷变形破坏机理,采用高性能注浆材料对失稳大巷进行注浆加固,并配合补强支护对其进行了综合治理。工程实践结果表明:大巷经过治理后,围岩未出现持续大变形现象,围岩承载能力满足大巷安全服务的需求。In order to solve the problems of roadway instability caused by the effect of superimposed stress on the roadway floor heave and coal pillar destruction,the deformation and failure mechanism of the roadway is analyzed through field investigation and theoretical analysis.Through the use of high-performance grouting materials,the unstable roadway was grouted and reinforced,and it was comprehensively treated with reinforcement support.Engineering practice results shows that after the roadway was treated,there is no continuous large deformation of the surrounding rock,and the bearing capacity of the surrounding rock meets the needs of the roadway safety service.
