· PDF Abstract: The mining method selection for underground mining is one of the most important decisions when designing a mine. This selection depends on the mining-geological, mining-technical and economic factors. The mining method selection for underground mining can be described as a multi-criteria decision-making process, as

· The selection of the mining method (MMS) refers to the procedure for picking an ideal extraction technique for mineral deposit. It is hard to switch the picked method, manipulate, and/or swap it with another after the MMS process has been finalized, and the mining of ore deposit has begun using the proposed approach [ 2 ].
