Mine designers often face difficulties in selecting an appropriate mining method; however, such a method should be selected based on ore and rock characteristics. The selection of mining methods can be considered a type of multi-criteria decision making, and this depends on many factors used in the selection process. The general method used in this field is the University of British Columbia (UBC) method, which determines the criteria of the properties that are compared to determine the best and worst of several mining methods. In this paper we used as new technique which defines as Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The criteria considered in the UBC method include general shape, ore thickness, ore plunge, and grade distribution, beside the rock quality designation (RQD), and the rock substance strength (RSS). This paper presents an improved TOPSIS method based on experimental design. Additionally, this paper will introduce a modified version of the UBC method that can be employed based on Excel sheet. The best mining methods is cut and fill stoping and top slicing with the same rank equal 0.72, and the second-best mining method is square set stoping with rank equal 0.65.

Selection of an appropriate mining method is a complex task that requires consideration of many technical, economical, political, social, and historical factors. The aim of this paper is developing a hierarchical model to selection the optimum mining method with the use of effective and major criteria and simultaneously, taking subjective judgments of decision makers into consideration. Proposed approach is based on the combination of Fuzzy Analytic Hierarchy Process (FAHP) method with TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) methods. FAHP is used in determining of the weights of the criteria by decision makers and then rankings of the methods are determined by TOPSIS. The proposed method is applied for Jajarm Bauxite Mine in Iran and finally the most appropriate mining methods for this mine are ranked.

Dobór odpowiednich metod wydobycia jest zagadnieniem złożonym i wymaga uwzględnienia szeregu czynników technicznych, ekonomicznych, politycznych, społecznych i historycznych. Celem pracy jest opracowanie modelu hierarchicznego dla doboru optymalnej metody wydobycia w oparciu o kryteria główne, uwzględniając także subiektywne oceny osób podejmujących decyzje. Proponowane podejście wykorzystuje metodę hierarchii procesów z wykorzystaniem procedur rozmytych (FAHP) w połączeniu z metodą TOPSIS, polegającą na określeniu "odległości" od rozwiązania idealnego. Metoda FAHP służy do określania współczynników wagi dla poszczególnych kryteriów decyzyjnych, następnie ranking metod przeprowadzany jest w oparciu o metodę TOPSIS. Proponowana metoda stosowana jest w kopalni Jajarz Bauxite w Iranie, służąc przy doborze odpowiednich metod wydobycia.
