针对压覆矿产资源开采工程量大、程序复杂的特点,以财务评价为基本评价方法,建立了以最大收益为目标作为压覆资源开采经济评价的收益模型,并确定了压覆资源价值、开采成本及搬迁成本基本模型中各参数的基准参数值。以收益模型为基础,进行了模型参数变量扰动的敏感性分析,分析得出铝土矿价格是模型中的最重要的敏感因素,并对其他敏感因素进行了敏感性排序,可为工程评价提供一定的指导。
Due to the features of large quantity of work and complex precedures in the mining of overlaid re-sources ,a profit model for overlaid mineral resources mining is built ,which takes maximum profit as the target with the financial evaluation method .Besides,the standard parameter values are determined in such basic models as overlaid mineral resource value ,mining cost and relocation cost .And the sensitivity to model parameter variables is analyzed based on the profit model .The result shows that the bauxite price is the most important and sensitive factor .And for other factors,their importance is also ranked hereby .The study provides certain guidance for the engineering evalua-tion.
