Choosing shaft sinking method by using the combination of Fuzzy AHP &Fuzzy TOPSIS approaches
نویسنده
چکیده
Shaft sinking is one of the main parts in underground mine planning. Shaft has various applications in underground mines e.g. minerals exiting flow, gases entrance or exit way, stope developments for exploitation etc. Considering that this section requires an abundance of expenses, management always following the election is the way that both terms have the technical considerations, economic constraints are also considered. Therefore, selecting shaft sinking method is one of the biggest concerns of underground mines management. There are some methods for this purpose including Delphi, ELECTRE, TOPSIS and AHP. This paper intends to use the combination AHP and TOPSIS methods under fuzzy environment in order to choose a ventilation shaft sinking method for Parvade mine located in coal zone of Tabas. The results indicate that RBM method is the most preferable approach, and drilling-blasting, Alimac, and SBM methods are preferred respectively.
