摘　　要：金口岭铜矿宝山矿段深部的铁铜矿体作为该矿危机矿山接替资源找矿勘查工作成果,对于延长该矿服务年限发挥了重要作用。详细论述了宝山矿段水文地质特征及工程地质特征,并对开采至标高-550 m中段时的矿坑涌水量及围岩稳定性进行了预测和评价。研究表明:(1)该矿水文地质单元属白家山小河流地下水系;(2)F11断层为宝山矿段的主要导水构造,位于泥盆系五通组顶部,与铜官山背斜走向一致,该断层为控制宝山矿体的主要断层,是未来采矿活动中最具威胁的导水构造;(3)依据宝山矿段水文地质条件,采用比拟法预测开采至-550 m中段时,矿坑正常涌水量约为13 307.46 m^3/d,最大涌水量为16 027.83 m^3/d;(4)宝山矿段岩石质量等级为III级,岩石质量中等。The Cu-Fe ore-body hosted in the depth of Baoshan Ore Section of Jinkouling Copper Mine is the found by conducting the prospecting and exploration work of replace resources of crisis mine of Jinkouling Copper Mine,which is help for extending the service length of the mine. The hydrogeological characteristics and engineering geological characteristics of Baoshan Ore Section of Jinkouling Copper Mine are discussed in detail,and mine water in-550 m section is predicted and the stability of the surrounding rock mass is evaluated. The study results show that：（1）the hydrogeological unit of the mine is belongs to Baijiashan little stream underground drainage;（2）F11 fault is the main water conducting structure,it is located in upper of Wutong Formation of Devonian,which trending direction is consistence to the one of Tongguangshan Anticline,F11 fault is the mine fault that is controlling the Baoshan ore-body,and it is the most serious water conducting structure in the future mining activities of Jinkouling Copper Mine;（3）according to the hydrogeological conditions of Baoshan Ore Section,the mine water inflow of-550 m section is predicted by adopting analogy method,the results show that the normal mine water inflow is 13 307. 46 m^3/d,the maximum mine water inflow is 16 027. 83 m^3/d;（4）the rock quality grade of Baoshan Ore Section is III grade,rock quality is belongs to medium level.
