摘　　要：地下水数值模拟是矿坑疏干排水设计的基础。该文以江西武山铜矿为研究对象,根据矿区地质构造、地层分布及水文地质条件,对矿区的岩溶-裂隙含水系统进行概化,建立地下水流三维数学模型,结合现场抽水试验资料,采用MODFLOW有限差分法进行地下水模拟,预测矿井在不同设计疏干水平下,地下水流场分布及矿区涌水量大小,为矿山地下水有效防治和安全生产提供依据。Numerical simulation of groundwater is the base for drainage and dewatering of deposit. This paper mainly discusses Wushan copper mineral deposit in Jiangxi Province. Based on the geologic structure, the strata distribution and hydrogeologic conditions in the mine area, the karst-fracture aquifer system is generalized in mining area. Combined with the data of pumping test, the three-dimension （3D） numerical model of groundwa- ter flow is established using finite difference method of Visual Modflow to simulate groundwater flow. The groundwater flow field distribution and mine inflow size are forecasted at different designed mining drainage level. The reliable basis is provided for controlling groundwater disaster effectively and safety rational mining.
