摘　　要：云盖山一矿630 m轨道下山西翼采空区突然涌水,经综合分析及实地调查判定,突水水源为边界小煤矿越界排水。矿井通过物探与钻探相结合精确判定小煤矿越界巷道位置、标高,设计施工堵水巷道、挡水墙,井下墙体连续浇筑,墙体前后围岩岩体注浆加固封闭,墙体设导管实现小煤矿积水水位观测与水源利用相结合。小煤矿水患治理工程成功实施,降低矿井排水量近80m3/h。Goaf in 630 m rail track of No.1 Yungaishan coal mine suddenly gushed water.Through comprehensive analysis of the mine and field surveys of the small coal,the source of water irruption was the cross-border drainage which created by border small coal mines.The location,elevation of cross-border tunnel in small coal mine was determined accurately by the combination of geophysical and drilling.The methods contained the designing and constructing water shut-off roadway,retaining wall,continuous underground wall casting,rock grouting around the rock wall and locating catheter wall,which achieved the conbinaton of water level observed and water used of small coal mine.The successful implementation of flood control projects in small coal mine reduced the mine displacement nearly 80 m^3/h.
