摘　　要：望云煤矿15号煤层导水裂缝带大部分可沟通至原3号煤层采空区积水,存在顶板采空区水害隐患,原3号煤层积水区已全部积水,水量较大,严重影响15号煤层煤炭资源的安全开采。针对这一情况,通过采用地面大口径钻孔抽排为主、井下钻孔疏放为辅的综合治理方案进行水害治理,成果显著,消除了水害隐患,确保了生产顺利衔接。Most of the water-conducting cracks in the No. 15 coal seam of the Wangyun Mine can communicate to the former No. 3 coal seam of ponding water, with a potential water damage in the top plate ponding area, and the former No. 3 coal seam of ponding water area, the amount of water was large, which seriously affected the safe mining of coal resources in the No. 15 coal seam. In view of this situation, the water damage was managed by adopting the comprehensive management scheme of ground large-diameter drilling pumping and drainage as the main and underground drilling and drainage as the supplementary, with remarkable results, eliminated the potential water damage and ensured the smooth connection of mining.
