摘要
在建立水文地质概念模型的基础上，运用ModFlow软件建立了研究区的地下水流模拟模型，并对模型进行了识别和验证。利用识别和验证后的模型分别建立疏干和不疏干条件下1990-2004年的模型，通过2个模型计算出疏干和不疏干情况下研究区的水量和水位，进而分析疏干排水对区域水资源的影响。
Yuan Bao-shan opencast mine lie on the Ying Jin river and LAO Ha river＇s impulsion plain, the aquifer in the upper part of coal is very thick. Water bring big difficulty to opencast mine. People adopt draining method to lower the water table, but because the quantity of draining water is too big to impact the regional water resources. The paper based on hydrogeology model, adopted visual Modflow establis- hing studied area＇s numerical simulation model. Using eligible model establish draining and undraining condition＇s model from 1990 to 2004. Through two different condition＇s models calculate studied area＇s water quantity and water table and analysis the influence of draining on regional water resources.
