摘　　要：煤矿地下突水问题不仅会干扰正常的采矿作业和采矿效率,还会增加煤矿安全工程的投入,甚至会导致严重的煤矿透水事故,严重威胁煤矿开采人员的人身安全。文章以我国某煤矿为例,对该矿开采面的突水危险性进行分析和评价,并利用综合探测、疏水降压和注浆加固技术对该煤矿煤层底板承压水问题进行治理,取得了较好的防治效果。The problem of underground water inrush in coal mines not only interferes with normal mining operations and mining efficiency,but also increases the investment in coal mine safety engineering,and can even lead to serious coal mine water seepage accidents,seriously threatening the personal safety of coal mining personnel.This study takes a certain coal mine in China as an example to analyze and evaluate the risk of water inrush from the mining face,and uses comprehensive detection,drainage and pressure reduction,and grouting reinforcement technology to treat the problem of pressurized water in the coal seam floor of the mine,achieving good prevention and control effects.
