“三图—双预测法”在滑动构造顶板水开采安全分区中的应用

Application of "Three maps two predictions" in the sliding structure roof water mining safety zoning

文章针对告成煤矿滑动构造特殊地质条件下严重的顶板涌水问题,通过收集、整理告成煤矿自建矿以来取得的水文地质资料,运用"三图—双预测法"对告成煤矿顶板安全开采分区,并以21051工作面为例,对工作面采前涌水量进行预测,结合工作面排水能力等实际情况提出工作面顶板水害理措施和方法。

Aiming at the serious problem of roof water inrush in special geological condition of gliding tectonics in Gaocheng coal mine,this paper collected the hydrogeological data since the completion of Gaocheng coal mine,used the ＂three maps two predictions＂ on division of Gaocheng coal mine roof safety mining,and taking 21051 working face as an example,predicted the water inflow before mining face Combined with the work surface drainage ability,put forward put forward measures and methods of the working face Roof water disaster.
