微震技术在煤矿注浆防治水过程中的检测分析研究

Detection and Analysis of Microseismic Technology in the Process of Water Prevention and Control by Grouting in Coal Mine

针对龙泉矿4301工作面底板突水问题,采用钻孔注浆法对工作面进行防治水工作,并采用地震检波器构建了微震检测系统,通过监测得到了注浆前及注浆中的工作面顶底板微震事件分布规律,指导了注浆控制注浆量及压力,实现了较好的注浆效果。

Aiming at the floor water inrush problem of 4301 working face in Longquan mine,the drilling grouting method is used to prevent and control the water inrush in the working face,and the seismic detector is used to build the microseismic detection system.Through the monitoring,the distribution law of microseismic events on the top and floor of the working face before and during the grouting is obtained,which guides the grouting control,grouting amount and pressure,and achieves better grouting effect.
