回顾三十二年来我省探明的矿产储量,从经济效果看,有些矿区勘探工作结束后,紧接着能进行设计开采,很快收回了地勘投资,经济效果是好的;但也有一些矿区,勘探程度虽然较高,却长期不能开采利用,地勘投资大量积压,经济效果差。笔者认为,造成地勘投资经济效果差的原因之一,是以往在矿产勘探中没有作矿床的技术经济评价和技术经济的全面分析。本文在总结以往地勘工作正反两方面经验的基础上,从宏观经济分析出发,试谈对我
Recalling the proven reserves of minerals in our province during the past 32 years, from the economic results, some exploration work in the mining area is completed, followed by design and exploitation, and the geologic exploration investment is recovered quickly, and the economic effect is good. However, some mining areas Although the exploration level is relatively high, it can not be exploited and used for a long time. Therefore, a large amount of backlog of geological exploration investment has poor economic results. In my opinion, one of the reasons for the poor economic effect of investment in geological prospecting is that there is no comprehensive analysis of the technical and economic evaluation and technical economy of mineral deposits in the past. On the basis of summarizing the positive and negative experiences of previous geological prospecting work and starting from the macroeconomic analysis,
