摘要

摘要边界品位（COG）是区分矿石和废物的一个简单的经济标准，而最佳COG表明了利用地质储量的最佳技术经济策略。COG优化过程是动态的，因此必须在所有处理阶段进行优化。莱恩算法的经典方法本质上是主观的；他使磨机的原矿品位保持不变一次，然后使其动态。因此，为了克服这些限制，本文提出了一种基于动态规划的多序列决策算法来确定露天金属矿床全局最优COG的新算法。

A new optimisation model for the selection of optimal cut-off grade using multi-sequential decision algorithm in open-pit metalliferous deposits

ABSTRACT The cut-off grade (COG) is a simple economic criterion that distinguishes between ore and waste, while the optimum COG demonstrates the best techno-economical strategy to utilise a geological reserve. The COG optimisation process is dynamic and, therefore, must be optimised at all processing stages. The classical approach of Lane’s algorithm is subjective in nature; he makes the mill’s head grade constant once and then makes it dynamic. So, to overcome these limitations, a new algorithm for determining a global optimal COG using a multi-sequential decision algorithm based on dynamic programming for open-pit metalliferous deposits has been presented in this paper.
