摘　　要：马坑铁矿区属于水文地质条件复杂的岩溶充水矿床。疏干地下水是地下开采面临的首要难题。如何解决地下水疏干问题是矿区水文地质条件研究的重点和难点所在。根据马坑矿区岩层含水性、岩溶水系统特征、构造及水文地质的特征,分析深部开采地下水疏干若干问题,并提出了解决问题的相应方案。Ma-Keng iron ore in Fujian is the water filling karst deposit with complex hydrogeologi- cal condition. The drainage of groundwater in Karst Deep Mineral Deposit is the primary problem faced by underground mining. It＇s still the focus and nodus of the the research on hydrogeological conditions to solve the problem of groundwater drainage at present. This pa- per, analysed the issue of groundwater drainage in Karst Deep Mineral Deposit and put for- ward the corresponding solutions, on the basis of the comprehensive introduction of the wa- ter-bearing feature of rocks in Makeng mining area, the characteristics and structure of the karst water system, and the hydrogeologieal significance.
