摘　　要：针对大斗沟煤业冲击地压显现次数频率高,释放能量大导致巷道煤岩失稳问题,利用冲击地压微震监测法确定监测采区震动能量频次以及震动相对位置,基于此,采用柔性让压支护配合深孔开采卸压技术措施人工超前释放煤岩积聚能量,有效降低冲击地压显现次数频率和释放能量等级。In view of the coal rock instability caused by high-frequency rock burst behavior and large energy release in Dadouyan Coal Industry Co.,the author proposes the technical measures of flexible yielding support coordinated with deep-borehole pressure relief to release the energy accumulation artificially by determining the seismic energy frequency and location through rock-burst microseism monitoring method,which can effectively reduce the rock burst behavior frequency and the energy release degree.

关 键 词：冲击地压 微震监测 柔性让压支护 深孔卸压
