Design of Decision-Making Techniques Using Improved AHP and VIKOR for Selection of Underground Mining Method

Abstract

Decision making is a process of selecting the best alternative from the pool of alternatives. This selection process depends on many influencing parameters; these parameters may be beneficiary or non-beneficiary. The proposed decision-making techniques were implemented in the appropriate underground mining method selection process. The selection of underground mining method depends on various geo-mining parameters such as technical, physical, mechanical, and economic parameters. In the proposed work, the selection of best mining method for bauxite deposit was implemented using Improved AHP and VIKOR. Improved AHP technique was considered to determine the weights of the influencing parameters. The proposed techniques can consider the association among the influencing parameters and alternatives. Results obtained by the proposed techniques were compared with the results obtained by other researchers for the bauxite deposit. The results showed that the suitable mining method for the specified criteria of the bauxite mine was conventional cut and fill.
