矿井出水水源判别的综合方法

摘要

In Muduchaideng coal mine, the max inrush-water gushing quantity of a long-distance drill hole, which located in a tunnel, is 220m3/h. By comparing water sample of this hole and water sample taken in the coal mine and considering the hy-draulic pressure and water quantity attenuation of this drill hole, the paper finally identifies the source of the inrush-water.%母杜柴登煤矿目前处于基建阶段,在回风巷道施工一个长距离钻孔。该钻孔涌水量一度达到220 m3/h,快速判别此出水来源,成为矿井急不可待的任务。文章通过对矿井先前采集以及该孔采集的水样进行详细的水质对比,并根据该孔简易放水试验水量衰减情况以及水压情况,综合判断出出水水源。
