Abstract: The paper summarized the characteristics，function and application of PFC numerical simulation software，and starts a numerical simulation research of low dilution ore drawing to solve the problem of the high dilution rate in Jinshandian Iron Mine. With PFC numerical simulation software, a numerical simulation on two different kinds of ore drawing methods which consist of low dilution ore drawing and existing cut-off ore drawing was carried out. After comparing with the results, it is discovered that it was completely feasible to adopt low dilution ore drawing in Jinshandian Iron Mine. So, the plan of low dilution ore drawing with the cut-off grade of 30% was recommended.
