摘　　要：王村煤矿5#煤层顶板砂岩裂隙水水量较小,但是对工作面回采影响较大,顶板淋水分散涌出,治理难度大。该矿根据14503综采工作面的水文地质条件,采用了工作面回采前进行超前钻孔疏放水的施工方法,使顶板水治理技术得到成功的应用。Although the roof sandstone fissure water content of 5#coal seam is small in Wangcun Coal Mine,for the positions of roof water inrush are dispersed,it is very difficult to solve the problem. Based on the hydrogeological conditions of№14503 fully mechanized mining face,using the method of advanced drainage technology by boreholes before coal mining,the roof water was treat successfully.
