露天开采整体优化方法

The Integral Optimization Method of Open-pit Mining

针对露天开采的整体优化问题，阐述了优化定理及实现整体优化的“动态境界排序法”。该方法可以直接对露天开采的最终开采境界、长期开采计划（即开采顺序）、生产能力和开采寿命等重要参数实施以最大净现值为目标的同时优化。

In view of the integral optimization of open-pit mining,the paper describes the optimization theorem and 'the dynamic perimeter sequencearrangement' for realizing the integral optimization.The method can be used directly for simultaneous optimization of the main parameters of open-pit mining such as final mine perimeter,long-term mining schedule (or mining sequence), production capacity and mining life with the maximum NPV (Net Present Value) as its object.
