在采矿技术经济分析比较中,经常用矿石损失、贫化指标作为鉴别优劣的主要判据,故有必要将它们综合成一个经济指标。本文推荐用单位储量盈利额r(元/吨)作为衡量的主要判据;也可根据矿石损失贫化所造成的经济损失,算出单位储量摊销。的损失额S(元/吨),作为判别优劣的根据。 本文用例题计算分析了两种经济计算方法的一致性,最后,简短讨论了这种经济计算中存在的问题。
In the economic analysis and comparison of mining technology, ore loss and depletion indicators are often used as the main criterion to distinguish between good and bad, so it is necessary to combine them into an economic indicator. This paper recommends using the unit reserve earnings r (yuan / ton) as the main criterion for measurement; also based on economic losses caused by ore loss and depletion, calculate the unit reserves amortization. Of the amount of loss S (yuan / ton), as a basis for determining the merits. In this paper, we analyze the consistency of the two economic calculation methods by using the example. Finally, we briefly discuss the problems in the economic calculation.
