GEOLOGY OF THE TONGYU COPPER DEPOSIT IN SHAANXI PROVINCE AND RESEARCH OF UNCONVENTIONAL METHODS FOR MINING
Author(s): Zhang Xu-yu, Li Yin-lao, Hu Min-zhi, Zhang Xuan-gu
Pages: 27-32
Year: 2013 Issue: 2
Journal: Geology of Shaanxi
Keyword: 铜峪铜矿; 非常规采矿; 拉槽; 贫化率;
Abstract: :铜峪铜矿床是火山岩磁黄铁矿黄铁矿型铜矿床,矿体多,矿床规模小,品位低;矿体厚度变化大,矿体与围岩属渐变过渡关系,采矿极易贫化.采用非常规开采,即开拓(直接沿矿体拉底、切割)—形成矿房—在矿房内按一定间距拉槽—最后在矿体下盘施工运输坑道—再按常规开采,有效降低了贫化率,提高了矿山的经济效益.
