摘　　要：紫金山金铜矿上部为金矿体,下部为隐伏厚大铜矿体,垂向无矿段50m左右。在上部金矿体露天开采的情况下,下部铜矿体同时进行地下开采。地下开采采用平硐-溜井联合开拓系统,为保证金矿与铜矿同时开采的安全,铜矿采用棋盘式框架结构空场采矿法,矿房矿柱分两步骤回采。经过技术与经济论证,一步骤矿房采用阶段矿房采矿法是合理的,于2004年完成试验研究并于2005年年末投产应用。The upper part of Zijinshan gold and copper deposit is gold bearing ore bodies, and its lower part is concealed massive copper ore bodies, between which in the vertical direction there is no ore body for some 50m. The upper part gold orebodies are mined by open pit, while the lower part copper orebodies by underground. The development system for underground mining is via adit-orepass, where open stope mining method with regular framework support, with room and pillar being mined separately. Technical and economical assessment show that sublevel stoping is a reasonable method to mine the room at one stage. The test was completed in 2004 and the technology was put into application in 2005.
