摘　　要：放矿截止品位的确定合理与否关系到矿山的综合效益,随着开采活动、市场经济指标的动态变化,有必要对截止品位进行动态优化计算。结合鲁矿集团下属两矿山的最优截止品位的研究,综合考虑矿产品价格、采选成本、地质品位、采选工艺等因素对于截止品位的影响,以最大盈利值为原则建立了截止品位动态优化模型,并通过黄金分割法求得了最优值。其结果为矿山生产决策提供了重要的理论依据。The reasonable determination of cut - off grade for ore drawing is related to the comprehensive benefit for a mine, therefore, the dynamic optimization of drawing cut - off grade must be made because of the dynamic changes of exploration and market economic index. Through studying the optimal cut - off grades of ore drawing for the tow mines of Luzhong Mining Cor- poration, and comprehensively considering the influences of min- eral prices, mining and mineral processing costs, geological grade, mining and mineral processing technologies on cut -off grade for ore drawing, a dynamic optimization model of cut - off grade was established based on the principle of maximum profit, and the reasonable cut - off grade was solved by golden section search method. The results have provided important theoretical basis for decision making of production.
