摘　　要：根据马鞍山高村铁矿露天采场矿区地质及水文地质特征,对矿区的基岩裂隙地下水系统进行概化。结合高村采矿场历史疏干资料和观测孔的地下水动态观测资料,建立了矿区地下水水流模型。然后按照露天采场的开采计划,论证矿坑地下水疏干对策,分别对2个开采规划期进行地下水疏干预测,为安全开采和经济有效地防治地下水提供设计依据。ABased on the geological and hydrogeological conditions of Gaocun iron mining open pit in Ma＇anshan, the hydrogeological conceptual model of bedrock fissure aquifer was generalized, combining with the historical drainage date of Gaocun stope and the obser- vation value of boreholes, the numerical model of groundwater flow was established. According to the mining plan of open pit, the drainage measure was developed, and groundwater drainage prediction for the two mining periods was made, providing bases for an ef- fective control of groundwater and a safe and rational mining.
