摘 要:为解决地应力异常区巷道变形、底鼓严重的问题,对常村煤矿南6采区的围岩地质力学参数进行测试且对原支护方案失效原因进行分析,在分析的基础上,提出全长预应力锚固强力锚杆锚索组合支护系统,通过掘进期间矿压观测结果表明:新的支护体系有效控制了围岩变形与破坏。In order to solve the problem of deformation and bottom heave of roadway in the abnormal area of geostress, the geomechanics pa- rameters of the 6 mining area in the south of Chang Village coal mine were tested and the reasons for the failure of the original support scheme were analyzed. On the basis of analysis, the paper puts forward the combined support system of full length prestressed anchor holt and cable, and through the observation of mine pressure during tunneling, the new support system can effectively control the deformation and damage of surrounding rock.
