摘　　要：为了加强深井冲击矿压预测情报有效性,介绍了SOS微震监测系统的结构、原理、布置、定位与监测信息后处理;针对采空区残余应力以及断层构造应力诱发冲击矿压的问题,以微震监测为基础,分析了不同地应力作用下可能的冲击危险。结果表明:微震活动持续不均衡活跃并呈增大趋势时有较高冲击矿压可能性;微震活动持续沉寂但矿压显现异常强烈时有较高冲击矿压可能性;微震监测系统在深井冲击危险等煤岩动力灾害的监测预报方面发挥重要作用。结论对于矿井冲击矿压监测与治理工作具有借鉴和指导意义。This paper introduced micro-seismic monitoring system＇ s structure, principle, layout, orientation and post-processing of monitoring information. Based on micro-seismic monitoring, this paper analyzed possible rock-burst danger induced by residual stress of gob or tectonic stress of fault. Results were showed as follows. When micro-seismic activity was continuous unbalanced active and showed increased trend, rock-burst danger was large. When micro-seismic activity was continuous recessional but underground pressure behavior was exceptional strong, rock-burst danger was also large. Micro-seismic monitoring system would play important role on the forecast of coal and rock dynamic disaster in deep mine. These results might provide reference to rock-burst monitoring and preventing.
