NPV在某多矿床露天境界优化中的运用

Application of NPV in the Optimization of Open-pit Boundary of a Multi-mineral Deposit

露天境界优化是露天开采设计的重要内容,需要综合考虑矿石价格、品位、资源贫化率、选冶回收率、选冶成本、矿山剥离成本、矿山采矿成本以及规模等众多因素。为探讨NPV在某多矿床露天境界优化中的运用,在该矿床资源三维模型的基础上,确定多个矿床边坡参数的最优方案,使资源开采经济效益最大化。

The optimization of the open-pit boundary is an important content of the open-pit mining design.It is necessary to comprehensively consider many factors such as ore price,grade,resource dilution rate,beneficiation recovery rate,beneficiation cost,mine stripping cost,mine mining cost and scale.In or⁃der to explore the application of NPV in the optimization of open-pit boundary of a multi deposit,based on the three-dimensional model of the deposit resources,the optimal plan for the slope parameters of multiple deposits is determined to maximize the economic benefits of resource mining.
