摘　　要：在分析甘肃某矿区的水文地质条件基础上,建立了研究区水文地质概念模型,运用国际的可视化标准软件VisualModflow对研究区地下水进行了数值模拟计算,预测了区内地下水水位随时间缓慢上升,地下水处于微弱正均衡状态,地下水位将以高于1m幅度升降,极限水位是1.6m,矿区地下水水位边界线将向东南侧(厂址范围)移动约214m,距离厂址范围边界最近287m,地下水水位上升后对拟建厂址范围内项目建设无安全影响,同时为今后研究矿区地下水资源的合理开发利用、矿区建设及环境保护等提供了科学依据。This article base on the analysis of the GanSu mining area＇ s hydro-geological conditions, and build a hydrology geology conceptual model, then the groundwater system is numerically simulated with the internationaly standard Visual Modflow in the research areaand forecast this area in the maintenance existing quantity military supplies invariable situation, the water level slow rise in the area. as the multi- annual variation tendency. ~he ex- cretion quantity and the quantity military supplies is approached equally, the water level will be higher than the rate of take-off and landing 1 m. then its altitude of the largest water level is 1.6 m. the phreatic water surface boundary line （factory site） will move approximately 214 m to the east south. And will be away from factory site boundary 287 m recently, it do not have the influence to plan to construct the factory site. The results can provide scientific basis ground water resources rational exploitation and utilization, the mining area construction and the environmental protection in the future
