摘　　要：为降低掘巷过断层期间冲击地压诱发风险,以郭屯煤矿3305轨道顺槽过DF55断层构造区为背景,分析了掘巷过断层期间的冲击危险性,采取了ARAMIS M/E微震监测系统区域监测、钻屑法和应力在线监测的局部监测预警技术,提出了大直径钻孔卸压和爆破卸压解危措施,保证了巷道顺利通过DF55断层影响区。In order to reduce the risk of rock burst induced during the period of driving roadway passing through faults,taking the 3305 track groove of Guotun Coal Mine passing through the DF55 fault structural area as the background,the risk of rock burst during the period of driving roadway passing through faults is analyzed.Local monitoring and early warning technologies such as the ARAMIS M/E microseismic monitoring system regional monitoring,drilling debris method,and stress online monitoring are adopted,hazard relief measures of large diameter borehole pressure relief and blasting pressure relief are proposed to ensure the smooth passage of the roadway passing through the DF55 fault affected area.
