| 摘 要： | 为了有效利用稀缺的地质资源,建立了以净现值(NPV)为目标函数的矿床经济评价模型.采用盈利法计算伴生元素的当量品位,并基于三维数字矿床模型,分别以目标函数最大化和净现值大于0为目标,得出最优边际综合品位和盈亏平衡边际综合品位的计算方法.应用所建立的模型对某铜钼矿的边际品位进行了优化计算,优化结果可为矿山的投资建设和生产规划提供准确的经济分析,并保证资源的最优化利用.

| Abstract: | In order to realize efficient development to scarce geological resources,an economic evaluation model for mineral deposits is established by taking net present values (NPV) as the objective function.The method of profit element is introduced to calculate the equivalent grades.Then,based on the three-dimensional digital deposit model,an optimization algorithm for calculating both of the optimum comprehensive cut-off grade and the break-even cut-off grade is developed when respectively directing to the object... |
