本文以矿床利润总额,净现值,内部收益率和投资回收期的经济效果指标探讨铀矿工业指标的边界品位。在既定的铀产品价格条件下,根据铀品位具有对数正态分布规律的特点,揭示了提高边界品位会降低单位产品成本,降低边界品位会增加铀金属开采量及产品的销售收入,边界品位的升降影响销售收入与产品成本,可在其中寻求利润总额最大的边界品位。本文强调采用净现值法选择铀矿边界品位时,既要考虑净现值大小的经济效果,在满足基准收益率的要求下又要考虑铀资源的利用率。
In this paper, the uranium industry indicators of the border grade are explored based on the economic results of total deposits, net present value, internal rate of return and investment payback period. Based on the uranium product’s logarithmic normal distribution rule under the condition of the uranium product price, it is revealed that increasing the border grade will reduce the unit product cost, reducing the border grade will increase the uranium metal mining volume and product sales revenue, The rise and fall affect the sales revenue and product cost, in which you can seek the largest total amount of the boundary grade. This paper emphasizes that when selecting the uranium boundary grade by the net present value method, we should not only consider the economic effect of the net present value but also consider the utilization rate of uranium resources under the requirements of the benchmark rate of return.
