微震监测技术在煤矿底板突水预警中的应用

Application of Microseismic Monitoring Technology in Early Warning of Water Inrush from Coal Mine Floor

以王家岭矿12313回采工作面为监测靶区,利用微震预警监测系统对矿井底板突水进行了动态微震监测研究。监测结果表明:12313回采工作面底板的总体趋势趋于稳定,共有地质异常区、断层异常区和工作面前方应力集中区8个异常区,监测结果为工作面底板突水预警提供了技术支持。

Taking the 12313 mining face of Wangjialing Coal Mine as the monitoring target,the dynamic microseismic monitoring of water inrush from mine floor is studied by using microearthquake early warning and monitoring system.The monitoring results show that the overall trend of the floor of the 12313 mining face tends to be stable,and there are eight abnormal areas,such as geological anomaly area,fault anomaly area and stress concentration area in front of the working face.The monitoring results provide technical support for the early warning of water inrush from the floor of the working face.
