In order ensure the stable ore quality,the ore-body morphological characteristics and grade distribution characteristics are shown by adopting three-dimensional modeling software,based on this,the quantitative predicting software of loss rate and dilution rate of open-pit mine is developed by an-alyzing the mining production techniques to provide the relatively accurate ore matching basic data.The ore matching process is analyzed in depth,the programming solver ore matching mathematical model un-der a number of constraint conditions is established.The intelligent ore matching software is developed by using VB and Matlab language to realize the functions of ore block orthogonal combination and program-ming solver and optimization to promote the development of quantitative and intelligentize ore matching work.The application results of the software show that the ore matching software developed in this paper has the characteristics of simple operation and practical function,it can make stable ore grade and make full of the low grade ore inside of mining boundary.Besides that,it also help to improve the ore compre-hensive utilization rate.On the whole,the effects of cost decreasing and benefit increasing are good.
