摘　　要：针对露天矿山规划与矿石质量管理的配矿需求,在爆堆品位分布预测的基础上,利用0-1整数规划模型,研究了露天矿配矿的优化方法,进而将其嵌入到DIMINE软件中,并以某水泥灰岩矿配矿设计为例,验证该技术的性能。结果表明,该露天矿配矿优化方法应用简单、配矿效率高、效果好,可有效提高企业的经济效益,对于指导矿山企业的有效生产与决策具有重要的意义。In view of the requirements of ore blending for ore quality management and open-pit mine plan, an optimiza- tion technique of ore blending for open-pit mine using a 0-1 integer programming model was proposed based on the grade distribution prediction for muck-pile. This method was then integrated into DIMINE. Taking the ore blending design for a cement limestone ore as an example, the performance of this optimization technique was verified. The results show this optimization technique for ore blending, being characterized by easier application and high efficiency in ore blending, can greatly improve enterprises＇ economic benefit. It is of important significance for guiding the operation and planning on mine.
