南岭成矿地区矿山深部找矿新进展

Recent Status of Deep Ore Prospecting in the Nanling Range

全国危机矿山接替资源找矿专项工作在南岭地区共安排项目30项,累计投入总经费4.7143×108元,其中中央财政2.4796×108元,地方财政投入2.595×107元,矿山企业投入资金1.9388×108元。新增332+333铅锌金属资源量5.737×106t,三氧化钨资源量3.94×105t,锡金属资源量2.62×105t,钼金属量资源量2.75×105t,金金属资源量35.5 t,锑金属资源量4.2×104t,铁矿石量3.968×107t,银金属资源量5149.7 t,铜金属资源量2.26×105t。9个项目取得重大找矿突破,新增资源量达到大型矿床规模;6个项目取得重要进展,新增资源量达到中型矿床规模,平均延长矿山服务年限17年,稳定职工就业49 464人,经济社会效益显著。同时,在深部找矿获得了一些新认识,对该区矿山深部找矿具有一定指导意义。

Thirty projects with tolal funds of 47.143 million RMB were arranged in the prospecting special program for continued resources of crisis mines in the Nanling Range. So far, achievements were focused on resource increases of 5.737 × 10^6 lolls Pb- Zn. 3.94 × l0^5 tons WOz, 2.62 × 10^5 tons Sn, 2.75× 10^5 tons Mo, 35.5 Ions Au, 4.2 ×10^4 tons Sh, 3.968 ×10^7 tons Fe ores, 5149.7 tons Ag, ag 2.26 ×10^5 tons Cu. Great progress was specially marked for nine projects by newly increased metal resources up to large-sized deposits. Six projects presented imporlanl progress with increases of resources to medium-sized deposits. This program integrated also significant new knowledge in deep metallogenic theory,, which is very usefid in deep ore prospecting in Ihe Nanling Range.
