摘　　要：矿井水是陕北重要的可利用资源,榆神矿区矿井水主要来源于第四系萨拉乌苏组地下水,其次有侏罗系基岩裂隙水,调查了11处煤矿的矿井涌水量,并与煤炭产量进行了比较分析,研究表明,榆神矿区矿井涌水量与煤炭产量直接相关,吨煤富水系数介于0.93～4.23m3/t之间,一般1.2m3/t,矿井涌水量主要受第四系含水层富水性的影响,开采达到一定面积后,大气降水直接影响矿井涌水量。这对于未来矿井防排水设计、煤矿安全生产及能源基地供水水源解决途径具有一定指导意义。The flushing water of coal mine mainly comes from Quaternary Salawusu Formation and the other from Jurassic System bedrock fissure waters. The authors inquired into 11 places of coal mining wastewater outcome, and compared wastewater outcome with coal outcome. The study shows, that the relationship between outcome of coal mining wastewater and coal output are close, the ton of water yield property is between 0.93 and 4.23 m^3/t , generally, it is 1.2 m^3/t. The water yield property of Quaternary effects the outcome of coal mining wastewater mainly, with the exploited area becoming large, which will be effected directly by atmospheric precipitation. It is of some significance for the future mine-drainage design, production safety of coal mines and solution of water resource in energy base.
