Abstract: Some large rock gold mine is attempted to adopt the two steps open stoping with subsequent caving mining method for the slowly inclined large and thick ore-body.According to the condition of multi-level and goaf groups，and second-step stopes mining under the condition of first-step goaf without management，as well as combining with the reconstruction production capacity requirements，the large panel stope high-efficient zoned mining scheme is put forward.The second-step stope is divided into two mining areas to retain barrier pillars between the two areas.The ore bodies in the footwall adopt sublevel open stoping and lateral caving with subsequent roof caving method，and the triangular ore bodies in the hanging wall used sublevel open stoping with positive caving method.Through the large panel stope high-efficient zoned mining industrial field test，high-efficient，economical and safety mining of slowly inclined large and thick orebody under the condition of multi-level and goaf masses are realized，which provides important technical support for the mines with similar conditions.
