基于Whittle软件的露天矿境界优化在西藏某矿的应用

Application of Whittle in open-pit mining limit optimization in some mine in Tibet

露天矿开采设计中一个很重要的环节就是境界优化,其目的是为矿山下一步开采矿设计和开拓提供参考和决策依据,同时能最大化的综合利用现有资源,将企业利益最大化,实现企业长期战略性规划。结合实例详细介绍利用Whittle软件进行动态综合的露天境界优化的过程,并通过对一系列优化结果的分析,结合净现值(NVP)最大这一原则选择出最优的露天境界,进而设计出最终的露天境界。

As an important part of open-pit mining,limit optimization can provide reference for open-pit mining design,meanwhile,it can maximize the comprehensive utilization of the resources and maximize the benefits of the enterprise,making the long-term strategic planning of the enterprise come true.In this paper,taking a open pit in Tibet as example,the operation of dynamic open-pit limit optimization process of Whittle software was introduced in detail;and through the analysis of a series of optimization results,combined with the principle of maximum net present value(NVP),the optimal open-pit was selected and the final open pit was designed.
