本文利用专门水文地质勘察资料，在充分研究分析某大型露天矿区水文地质条件的基础上，通过对凹陷开采后矿坑水的比算与预测，对其防治方案（法）进行了探讨。提出：侵蚀基准面以上采掘时靠坡降自然排水；凹陷开采，封闭境界圈后，先堵后排，施工后收到了实效。
Based on the full analysis of the hydrogeological conditions in a large open pit mine, this paper explores the control scheme (method) through the ratio calculation and prediction of mine pit water after the exploitation of hollow pits. It is proposed that natural drainage should be carried out by slope reduction during the excavation above the erosion datum. When the sag is mined and the boundary of the boundary is closed, the block is drained back first and the actual effect is achieved after construction.
