摘　　要：结合张双楼煤矿以往矿井开采实践中的水文地质资料以及新施工探查验证钻孔等基础资料,系统分析西一采区7、9煤顶板基岩条件、重复采动覆岩破坏规律、第四系底砾层的富水性规律以及顶板含隔水层结构等,合理确定西一采区的安全开采上限,解放煤炭资源约222万t,保证了矿井安全高效生产和持续发展,对类似条件矿井具有借鉴意义。Combined with the hydrogeological data in the past mining practice of Zhangshuanglou Coal Mine and the basic data of new construction exploration and verification drilling, the roof bedrock conditions of No.7 and No.9 coal seams in the West No.1 mining area, the damage law of overburden rock caused by repeated mining,the water abundance law of Quaternary bottom gravel layer and the structure of roof aquifuge were systematically analyzed, so as to reasonably determine the upper limit of safe mining in West No.1 mining area and liberate about 22. 2% of coal resources.The safe and efficient production and sustainable development of the mine were ensured, which has reference significance for similar mines.
