矿山地区一方面采矿存在着水患，另一方面又因疏干排水而使日常生活缺水。目前我国有关矿区供排结合的实例并不多见。以大同矿区口泉沟南为例，分析了该区的地质、水文地质条件，并用数学模型的有限元法评价了地下水资源的允许开采量。同时提出和论证了最佳开采方案。 Mining area on the one hand there is a mining of floods, on the other hand due to dry drainage and make daily life water shortages. At present, there are not many examples of the combination of supply and drainage in our country. Taking Datunougou South of Datong Mining Area as an example, the geological and hydrogeological conditions of the area were analyzed. The allowable production of groundwater resources was evaluated by the finite element method of mathematical model. At the same time proposed and demonstrated the best mining program.
