摘　　要：通过访问生产煤矿,开展地面调查,采用15个施工钻孔数据资料对重庆观音峡背斜新店子井田水文地质条件进行了分析。新店子井田面积27.64km^2,以侵蚀、剥蚀、溶蚀低山丘陵岩溶地貌为主,区内溶蚀类型主要以溶蚀裂隙为主。富水性中、强含水层,水文地质勘探类型划为三类二型,即岩溶裂隙充水矿床;水文地质条件中等;矿井的充水因素主要有顶、底板,断层充水等,预测矿井一般涌水量22388m^3/d,丰水期涌水量为67164m^3/d。The Guanyinxia anticline is characterized by karst landform.Area of the Xindianzi well field is 27.64 km^2.Site investigation and data from 15 drilling holes indicate that its hydrogeological exploration types should belong to the 3rd type of the 2nd class which is characterized by filling water in karst fissure with moderate hydrogeological conditions.The main factors of mine water-filling are roof,floor,fault water-filling,etc.The general inflow of mine water is estimated at 22388 m^3/d with 67164 m^3/d in flood season.
