Abstract: 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:①the hydrogeological unit of the mine is belongs to Baijiashan little stream underground drainage;②F11 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,F11 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;③according 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;④the rock quality grade of Baoshan Ore Section is III grade,rock quality is belongs to medium level.
