在矿床的地质经济评价实践中,用于确定露天开采和选矿技术经济参数的几种方法具有一系列的严重缺点。直接计算法太繁琐,类比法和单位成本法不准确,并且和逐项作业法一样要在计算中引入系统的修正值和校正,因而大大限制了矿石采掘和加工的设计前框算。此外,当进行露天开采时,上述任一方法都不能单独用于矿床地质经济评价的方案模拟。 Several methods for determining the economic parameters of open pit mining and beneficiation technology have a series of serious shortcomings in the geo-economic evaluation of the deposit. The direct calculation method is too complicated, the analogy and the unit cost method are not accurate, and the system-like correction and correction are introduced into the calculation just like the item-by-item operation, which greatly limits the design calculation of ore mining and processing. In addition, none of the above methods can be used alone to simulate the geologic economic evaluation of a deposit when open-pit mining is conducted.
