东坪金矿是一座有三十多年开采历史的地下矿山。根据政府实现“无矿市”的目标要求,为保证矿山的经济效益,并确保在矿山被关停前充分回收国家资源,有必要对东坪金矿床的工业指标进行重新论证。采用地质方案法对拟定的三套工业指标方案进行技术经济评价,从资源综合利用率,经济效益等方面对东坪金矿工业指标进行了方案比选,结果表明,方案二(边界品位1.0g/t,边界品位2.0g/t)适应当前的技术经济条件和产业政策,资源利用率最高,且经济效益最好,推荐作为东坪金矿的矿床工业指标。
Dongping gold mine is an underground mine with more than 30 years of mining history. According to the government’s goal of “ore-free city”, in order to ensure the economic benefits of the mines and ensure that the national resources are fully recovered before the mines are shut down, it is necessary to re-demonstrate the industrial indicators of the Dongping gold deposit. The geological program method was used to carry out the technical and economic evaluation of the three sets of industrial index schemes. The industrial indexes of Dongping gold mine were compared and selected from the aspects of comprehensive utilization rate of resources and economic benefits. The results showed that in the second scheme (boundary grade 1.0g / t, the border grade 2.0g / t) to adapt to the current technical and economic conditions and industrial policies, the highest resource utilization, and the best economic benefits, recommended as the Dongping gold deposit industrial indicators.
