摘　　要：针对李家壕煤矿浅埋深薄软基岩的巷道赋存条件,以11216工作面回风平巷为背景,对巷道顶板岩层的变形规律进行了监测研究。提出了采用锚杆锚索联合支护控制巷道围岩变形,并分析了锚杆锚索联合支护的原理。Aiming at the shallow and thin-and-soft bedrock occurrence of roadway in Lijiahao coal mine, the roof strata deformation rule was studied on the background of the tailgate in longwall face 11216. Adopting bolt-cable anchor support to control roadway surrounding rock deformation is proposed, and its support principle was analyzed.
