摘　　要：元宝山露天矿水文地质条件复杂，矿坑疏干引起含水层疏干、边界移动、河流成了悬河为评价疏干水量及疏干所引起的矿坑及其周围地区地下水位的降低情况，建立了一个适合露天矿排水疏干的二维水流模型，对疏干引起的上述特殊问题提出了相应的处理方法，模型计算值与实际观测值拟合良好。The hydrogeological condition of Yuanbaoshan opencast mine is very complicated.Water drainage from the opencast mine leads to some problems,such as dried aquifers,shifting of a boundary,and suspension of river.In order to evaluate the quantity of water to be drained and the effect of water drainage on reduction of ground water level in an opencast and its nearby regions a 2 D water flow model is established for water drainage from the opencast mine together with a method for solving the abovementioned problems.The simulated data agree very well with the field data (e.g.the mean absolute error of head is 0 33～0 44m)
