最终境界圈定和开采计划设计是露天矿优化设计的两大要素，对露天矿整体规划和经济效益都有重要影响，然而在可持续发展背景下，这两大要素设计存在两个问题，一方面，无论是境界圈定还是开采计划设计，仍然是以经济效益最大化为目标，对环境因素和社会因素的考虑相对较少，或者考虑得不够全面，对可持续发展的三大要素（经济、社会、环境）同时考虑的几乎没有；另一方面，最终境界和开采计划优化一般是独立进行的，由于二者整体优化的高度复杂性，相关的研究成果较少，且在整体优化过程中对环境问题和社会问题的考虑更是没有。鉴于此，本项目基于锥体排除法基本原理，分别产生经济最优境界、地质最优候选境界序列和地质最优开采体序列，采用迭代算法和动态规划法将矿山经济因素、环境因素和社会因素纳入到露天矿最终境界和开采计划优化当中，建立基于可持续发展的金属露天矿境界-计划整体优化算法和模型，实现理论和方法上的突破。

Ultimate pit and mining plan are both elements of open pit optimization, which have important effect on total planning and economic benefit of open pit mine. However, the elements have two problems. On the one hand, whatever ultimate pit delineation or mining plan design, takes maximum economic benefit as the main objective function and considers relatively little or incomplete on environment and society. Taking economy, society and environment together is less especially. On the other hand, optimizing ultimate pit and mining plan is independent. For the highly complex of optimizing the two together, the relative research achievements are fewer, and taking environment and society into whole optimization is none. In view of this, based on the fundamental of cone exclusion, economic optimum pit, geological optimum pit sequences and geological optimum push-back sequences are generated. Terative algorithm and dynamic programming method are used to take economy, environment and society into optimizing ultimate and mining plan. Then, based on the sustainable development, the whole optimization algorithm and model of open pit metal mine is built to achieve a breakthrough on theory and method.
