摘要

大坪金矿床是哀牢山成矿带上的大型金矿床。矿区保有资源量较少,为矿山生产可持续发展,查明矿体是否向深部延伸,需进行研究。北部矿段,开采标高在1356-650m,矿石类型为方铅矿化、黄铁矿化石英脉型金矿石,在V1-2-3号矿体,通过构造叠加晕、矿体侧伏规律等预测矿体向深部延伸,在35线用钻孔验证,于408m标高见矿,金品位24.70g/t,真厚度0.17m。老金山矿段开采标高在946-330m,矿石类型主要为黄铁矿化、铁白云石化石英脉型金矿石,少量磁铁矿化、黄铁矿化金矿石,在15线深部采用钻孔探索,在110m标高控制V52号矿体,金品位1.40g/t,真厚度0.16m。
        Daping Gold Deposit is a large-scale gold deposit in the metallogenic belt of Ailao Mountains. For the sustainable development of mine production, it is necessary to study whether the orebody extends to the deep or not. In the northern ore section, the mining elevation is 1356-650 m, and the ore type is galena mineralization and pyrite quartz vein type gold ore. In the ore body of no. V1-2-3, the deep extension of the ore body is predicted by structural superimposed Halos and the regularity of lateral declination of the ore body The gold grade is 24.70 G/T and the true thickness is 0.17 m.The mining elevation of Laojinshan section is 946-330 m, and the ore types are mainly pyrite, iron dolomite and quartz vein type gold ores, a small amount of magnetite and Pyrite Gold Ores The ore body V52 is controlled at 110 m level, the gold grade is 1.40 G/T, the true thickness is 0.16 m.
