One of the most critical and complicated steps in mine design is to select an suitable mining method based upon geological, geotechnical, geographical and economical parameters. Since there are many factors involved for the selection of mining method, which is decision-making process, the problem is very difficult to solve. In this paper, Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) with 12 criteria is used to develop a suitable mining method for the Ghale-zari copper deposit in Birjand. Three alternatives (Shrinkage stoping, Sublevel stoping and cut and fill stoping) are evaluated. The studies show that the suitable mining method appropriate mining technique for this deposit with regard to the present situation is shrinkage method.
