“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 and Two Predictions Method on Roof Water Safety Partition with Gliding Structure

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"对告成煤矿顶板进行安全开采分区,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了工作面顶板水害管理措施和方法。

Aiming at the serious roof water problems under special geological conditions of sliding structures in Gaocheng Coal Mine,by collecting hydrogeological data acquired from construction of this coal mine,safety mining of roof water was partitioned for Gaocheng coal by using three maps and two predictions method. Taking the 21051 working face as a case,it forecasted the water inflows of working place before mining and put forward the measures and methods of working face roof water disasters combining with the practical situation of working face drainage ability.
