忻州窑矿8939工作面冲击地压治理技术及应用

Management technology and application of rock burst in 8939 working face of Xinzhouyao Mine

针对近年同煤集团忻州窑矿冲击地压灾害异常活跃的问题,本文以冲击地压诱发成因分析为基础,提出钻屑法、矿压法、电磁法、微震法、指数法等预测预报技术和超前泄压、强制放顶、加强支护、合理避让等治理技术并进行现场应用。

For the problem of active rock burst disaster Xinzhouyao Mine of Datong Coal Mine Group in recent years,based on the analysis on the inducing factors of rock burst,the forecasting technologies of drilling cutting method,mine pressure method,electromagnetic method,seismic method,index method and the management technologies of advanced decompression,forced caving,strengthening support and reasonable avoidance are proposed and are applied on the site.
