摘要
开滦东欢坨矿是水文地质条件复杂矿井,曾发生过数次井巷工程及采面突水,针对2286综采工作面涌水大的开采特点,为防治水害,研究了疏水降压和水煤体分离综合治理技术,在应用中取得良好效果,实现了安全高效开采。
Dongh ditions. It has experi According to the char der to control the wa water-coal separation uantuo Mine of Kailuan Group is a mine with complex hydrogeological conenced water bursting many times in mining faces and excavating process. acteristic of large water inrush in 2286 fully mechanized mining face, in orter disaster, the comprehensive technology of draining depressurizing and is studied, which has obtained good effect in application, and the safe and efficient mining has been achieved.
