摘要
介绍了波兰ARAMIS M/E微震监测系统在华丰煤矿冲击地压防治中的应用,通过矿震事件具体定位和定点放炮,分析了微震监测系统监测精度与可靠性。应用结果表明:该系统在三维空间定位精度高,平面定位误差小于20m,垂直定位误差小于15m,符合系统定位要求。系统能通过监测数据对采煤工作面冲击地压危险程度进行评估,评价出工作面每天的冲击地压危险程度,为矿井进行冲击地压预测预报提供科学依据。
The paper introduced the application of ARAMIS M/E microseismic monitoring system of Poland on the rockburst prevention in Huafeng coal mine.The monitoring precision and reliability of microseismic monitoring system were analyzed by locating of mine earthquake event and shooting in fixed points.The application results showed that the location precision of this system is high in three-dimension,location error is less than 20m in plane and less than 15m in vertical direction,it reached the request of system location.The system can evaluate the criticality of rockburst in working face by use of monitoring data and the criticality of rockburst in everyday can be evaluated.It provides scientific basis for coal mine to forecast rockburst.
