摘要
本文介绍了新疆鄯善县沙尔湖东露天煤矿水文地质特征、补给、径流、排泄条件。露天区的充水因素主要为大气降水和含水层中地下水直接充水作用。采用"大井法"来计算矿坑涌水量,矿坑涌水量的预测结果和矿区首采区实际涌水量接近。因此,该方法对本地区其他煤矿开采具有指导意义。
This paper introduces the hydrogeological characteristics, groundwater recharge, runoff and discharge conditions of east Saerhu opencast coal mine in Shanshan County, Xinjiang. Water filling factors in opencast coal mine mainly are the atmospheric precipitation and the direct water filling effect of groundwater in water bearing strata. Used ＂open well method＂ forecasts the mine groundwater discharge. The prediction result of the pit water is close to the practical water flow of the first mining district. Therefore, this method is of guiding significance for the mining of other coal mines in the region.
