冲击地压防治在东海煤矿的应用

Application of rock burst prevention in Donghai Coal Mine

东海煤矿采用钻屑法、电磁辐射仪和人工观测顶底板两邦位移量等预测监测工作;对工作面顶板进行注水松动预裂爆破,对煤柱区域的本煤层进行打钻注水进行压力释放等措施简单、实用、可靠;管理上控制工作面割煤方式、循环进度和加强支护措施,有效的防范了应力集中。这些防治措施对矿井地质条件复杂,冲击地压破坏形式多样的矿井,具有一定的借鉴参考意义。

using the method of drilling bits ,electromagnetic radiation and artiifcial observation of roof and lfoor displacement prediction and other monitoring measures in Donghai coal mine, injecting water and loosening pre-split blasting on the roof of working face, drilling and injecting water in the coal pillar area of the seam to release pressure, which is simple and practical, reliable measures .Controlling the working face coal cutting methods, cyclic schedule and strengthening the supporting measures in management, which effectively prevent stress concentration. The prevention measures have certain reference signiifcance for mines that mine geological conditions are complex, diverse failure forms of rockburst.
