| 摘 要： | 基于盈亏平衡法的思路,推导出边界品位动态优化数学模型.该模型可以根据市场价格的变动,动态确定最低工业品位.这一动态优化方法以安徽某铜矿山为研究对象,先根据当前市场价格,得到最低工业品位,然后在品位区间0.1％～0.4％间按0.05％间距计算各品位矿体储量,采用贴现现金流法对矿山价值进行详细估算,估算结果验证了优化模型的临界值,并以最大累计净现值为指标确定最优开采边界品位.

| Abstract: | This study deduced a mathematics model of dynamic optimization of cutoff grade based on profit and loss balance method theory.The model determined the minimum industrial grade dynamically according to the fluctuation of market price.The dynamic optimize method took an ore boby of Anhui as study object,got the the minimum industrial grade based on the present market price ,then calculated reserve for the different grade from 0.1% to 0.4% with an interval of 0.05% and then estimated the mineral value using discounted cash flow method, the result verified critical value of optimization model and determined the optimum cutoff grade finally with the max accumulating net present value as an indicator |
