| Abstract: | In view of the requirements of ore blending for ore quality management and open-pit mine plan,an optimization 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. |
