摘　　要：针对星村煤矿高构造应力区域煤巷掘进过程中已支护区域多次出现锚索张剪破断的现状,通过地应力测试等研究确定失效原因,对原有支护体系进行优化升级,采取全长锚固、提高锚索预紧力、顶板深孔卸压爆破措施,有效地满足了巷道支护要求,防止了支护破坏现象,未再出现锚索断裂等问题,确保了矿井高构造应力区巷道掘进安全。According to the present situation of tension and shear breaking of anchor cable in the coal roadway in the high tectonic stress area of Xingcun Coal Mine,the failure reason is determined through the study of ground stress test,and the original support system is optimized and upgraded.the measures of full-length anchoring,improving anchor cable pretightening force and roof deep-hole pressure relief blasting are adopted to effectively meet the requirements of roadway support,prevent support failure,and no anchor cable fracture occurs again.The safety of roadway driving in the high structural stress area of the mine is ensured.
