摘　　要：本文提出了适用于露天矿疏干排水的二维及三维水流模型。模型针对露天矿特有的问题如含水层疏干、边界移动以及剩余水头预测提出了相应的处理方法。模型用于描述元宝山露天煤矿及其周围地区地下水位在疏干阶段的下降情况，计算值与实际观测值吻合良好（平均绝对误差0．33～0．40mm）。Two dimensional and three dimensional models for water flow fit for dewatering in an opencut mine are presented. Treatments of special problems for the opencut mine are suggested, such as drying up of the aquifer, boundary movement and prediction of residual head. The models are used to describe the state of ground water level decline during dewatering. The calculated values matched well with field data (mean absolute error 0.33-0.40m).
