摘　　要：通过对金沟煤矿区域及井田水文地质条件的综合分析,井田范围内划分出7层含水层,其中对矿井开采形成安全威胁的主要含水层有:第四系全新统冲、洪积砂砾石层—孔隙潜水含水层、侏罗系下统塔里奇克组下5号煤层顶板—承压含水层、侏罗系下统塔里奇克组下9号煤层底板—承压含水层、侏罗系下统塔里奇克组下10号煤层顶板—承压含水层。通过大井法和集水廊道法分别计算了井田西部、东部+1 300 m标高矿坑涌水量。井田西部开采下5号煤层初期采区预测涌水量为209.77 m^3/d;开采下10号煤层初期采区预测涌水量338.29m^3/d。井田东部开采下5号煤层初期采区预测涌水量为1 441.21 m^3/d;开采下10号煤层初期采区预测涌水量1 411.68 m^3/d。针对矿区的水文地质条件,总结出超前探水、放水降压、预留煤柱等防治水措施。Through comprehensive analysis of field hydrogeological conditions and Jin Gou Mine area, 7 layer aquifers were divided within the scope of mine, and main aquifers threatening safety mining included： Quaternary Holocene rushed-diluvial gravel stone layer, Lower Jurassic Taliqike Formation Lower No.5 coal seam roof-confined aquifer, Lower Jurassic Taliqike Formation Lower No.9 coal seam roof-confined aquifer, Lower Jurassic Taliqike Formation Lower No.10 coal seam roof-confined aquifer. Based on big well method and catchment corridor method, the west and the east mining field ＋1 300 m elevation mine water inflow were calculated respectively. Water inflows of initial mining field in western mining Lower No.5 and No.10 coal seam were predicted as 209.77 ms / d and 338.29 ms / d respectively. Water inflows of initial mining field in eastern mining Lower No.5 and No.10 coal seam were predicted as 1 441.21 ms / d and 1 411.68 ms / d respectively. Based on hydrogeological conditions of mining area, water control measures of advanced water exploration, water dropping decompression, reserved coal pillar and so on were summarized.
