摘要
瑶岭矿业公司北峰坳区矿脉群由31条大小矿脉组成,有工业矿脉6条,现已探明的海拨450～646m矿体尚未开采,探明工业储量WO32604.26t,Sn金属量279.12t,Bi金属量334.94t。本文针对北峰坳区矿产资源特点,研究制定了开采工程技术方案,并详细进行了技术论证和经济分析,以确保该部分矿产资源能安全高效地获得回收。
Beifengao group of lodes is formed by 31 lodes, in which there are 6 i ndustrial lodes. Now 450-646 m level orebody haven't been mined,and proved ore c ontains 2 604.26 t WO3,279.12 t Sn and 334.94 t Bi. In view of the mineral reso urce characters at Beifengao mine area,the mining project plan is worked out,dem onstrated and analysed in economy,which can ensure recovering this part of miner al resource effectively.
