摘　　要：对安徽省宿松县廖河大理岩矿区气象、水文、地形、地貌、地层和岩层富水性特征进行了研究,查明了地表水和地下水的补给、径流和排泄条件,分析了矿床充水水源与途径,地下水及地表水的动态变化规律。研究表明:(1)矿区的矿床类型是以溶蚀裂隙为主的岩溶充水型矿床,矿区水文地质条件为中等类型;(2)采用大井法预测的矿区北矿段首采段和终采段的矿坑涌水量分别为103 978,107 948 m3/d。Through the study of the meteorological characteristics,hydrogeological characteristics,topographic characteristics,geomorphic characteristics,stratigraphic characteristics and water-rich characteristics of rock stratum of Liaohe marble mining area in Susong County,the recharge,runoff and excretion conditions of surface and groundwater are analyzed,filling water source and filling way of the deposit are discussed,besides that,the dynamic variation law of surface water and groundwater are studied.The results indicated that：①the deposit in the mining area belongs to karst fissure water filling type deposit,the hydrogeological conditions of the mining area belongs to medium type;②based on big well method,the prediciton results of pit water inflow of the first and final mining sections of the North Ore Block are 103 978 ,107 948 m 3/d.
