Application of Linear Programming to Blending Research in Fu-Shan Iron Mine

There are three.nining stopes in Fu-shan Iron Mine. Based on th eir ore-tonnage, Ore-grade, sulphur content and silica content cond iti ons, reasonable blending of raw ores has to be carried out in order to make the commercial ore fulfilling the grade index requirqement and obtaining the optimizing profit index.
In this paper linear programming simplex method is used to solev the ore blending system giving the mathematical model for the Fu-shan iron ore blending problem and its corresponding simplex method chard This is carried out in the M-150 compater using FORTRAN program.
From the computing result we obtian the optimizing ore-blending system analysis of the influential factors of promoting profit index poin ting out the suitable ore-blending system used in Fu-shan Mine practi on and suggesting the opinion of further promoting the economical benefit.
