综合防治水技术在煤矿的应用

针对东庞矿受奥灰水威胁大、防治水工程量大、难度高,水文地质条件复杂的问题,结合井田实际情况,在矿井防治水方面采取综合物探、综合钻探、分区建立防水闸墙、注浆堵水等措施。实践表明,以上方法可有效探查异常区内实际情况,并可利用现有钻孔通过注浆封堵改造异常区,实现了矿井分区隔离,缩小水患影响范围,为煤矿安全生产提供了可靠保障。

Comprehensive Water Prevention and Control Application Technology in Mine

Based on Dongpang Mine threatened by grey water, large volume and high difficulty of water prevention and control, with complicated hydrogeological conditions, in combination with the practical situation of mine, comprehensive geophysical prospecting, drilling, partition wall, grouting water plugging waterproof gate and other measures were adopted in mine water prevention and control. The practice showed that the above method can effectively detect abnormal area actual situation, and use existing drilling through grouting seal transformation anomaly, realized coal mine the partition isolation, narrowing the scope of flood impact, provided a reliable guarantee for coal mine safety production.
