摘要
随着采空区面积的增大,采空区积水越来越多,为了疏排李家塔煤矿采空区积水,利用地层分析法和导水裂缝带预计方法,分析了矿井涌水的主要水源构成,查清了采空区积水的来源。采用工作面串联埋管的方式疏排采空区积水,解决了矿井的主要水害问题,保证了矿井的安全生产。
With the increase of the gob area, more and more water accumulated in the gob area. In order to remove the gob water in Lijiata Coal Mine, analysis was made on the formation of the main water inrush sources by using the strata analysis method and the estimated method of the water flowing fractured zone, and the gob water sources were found out. The series-buried pipes in the working face were used to remove the gob water, this thus solved the problem of the main water disasters and guaranteed the safe production in the mine.
