摘    要：针对紫金山金铜矿储量大、品位低的特点,以及上部金矿露天与下部铜矿地下同时大规模开采的状况,详述了紫金山金铜矿地下开采大直径深孔阶段矿房采矿法工艺过程及技术参数,提出了露天与地下同时开采应采取的综合措施。紫金山金铜矿大直径深孔阶段矿房采矿法的应用达到了低成本、安全、高效开采的目的,取得了很好的经济效益和社会效益。

Abstract: The reserve volumn of Zijinshan gold-copper mine is high,while the ore grade is low.Aiming at the upside gold ore open pit mining and underpart copper ore underground mining status,the underground big-diameter deep-hole stage room mining technology and parameters are described in detail.Comprehensive measures for simultaneous open pit and underground mining are put forward.The big-diameter deep-hole stage room mining technology is low cost,safe and high-efficiency.Good economic and social benefits are achieved.
