对于露天金属矿山的开采规划模型,会有不同的变量参数且每个参数对模型的影响程度不同. 以某露天铜矿为工程背景,利用3 Dmine软件在不同的变量参数组合作用下得出其开采规划模型和相应的优化方案,将正交设计与方差分析有机结合,通过对优化方案当年净现值的分析来求解模型中每一个参数的灵敏度. 结果显示,精矿价格对开采规划模型的影响最大.
對于露天金屬礦山的開採規劃模型,會有不同的變量參數且每箇參數對模型的影響程度不同. 以某露天銅礦為工程揹景,利用3 Dmine軟件在不同的變量參數組閤作用下得齣其開採規劃模型和相應的優化方案,將正交設計與方差分析有機結閤,通過對優化方案噹年淨現值的分析來求解模型中每一箇參數的靈敏度. 結果顯示,精礦價格對開採規劃模型的影響最大.

There are different variable parameters in production planning model of open-pit metallic mines and each parameter has influence on the model in different magnitude. The paper takes one open-pit copper mine as the engineering background,by using 3Dmine software under different combination of variable parameters concludes their production planning model and the corresponding optimization solution. Through the organic combination of orthogonal design and variance analysis and the analysis of the contemporary net present value of the optimization scheme,the sensitivity of each parameter in the model is calculated. Results show that the concentrates price has the largest impact on the production planning model.
