During the mining process of nonferrous metal mines,according to specific concrete conditions of the mineral deposit,from the technical and economic points of view,the optimal method is designed.Through the application in the ore mining in this paper,the sublevel caving and stage room mining method is suitable for the ore body in medium thickness located in fractured hanging wall.The result shows that comprehensive utilization of methods has great significance.

Mineral vein of Dongshan deposit in Linglong gold field is numerous,the relation of mineral vein is complex and mineral vein have the obvious phenomenon of convergence,separation,reunion.Through the research of distributed regulation,geology characteristic,country rock alteration,mineral vein with rock vein of vein No.18,47,50,176N,48,as well as comparisons of the complexion of space distribution,occurrence,and grade variation Metallogenesis is summarized,finding out the mineral enrich to gather the beneficial part,which provides geological references for exploration.
