      Purpose. The purpose of this paper is to reevaluate the currently used underground mining method with the intention to verify if cut-and-fill stoping method is appropriate for deep future excavation mining levels > 800 m below the ground sur-face.

      Methods. Decision-making methods i.e., Analytical Hierarch Process (AHP) and Fuzzy Multi-Attribute Decision-making Methods (FMADM), and UBC selection tool are implemented.

      Findings. According to UBC approach six alternatives – Block Caving, Cut-and-Fill Stoping, Sub-level Caving, Sub-level Stoping, Square Set Stoping, and Top Slicing have been considered as technically feasible alternatives. Results shows that cut-and-fill stoping method is the optimal mining method for deep excavation mining levels. Optimal underground mining method for Trepça mine due to the priority of this alternative (0.443) is the highest value compared with the other alternatives.

      Originality.This study attempts to find most suitable underground mining method among the possible alternatives based on AHP and FMADM techniques.

      Practical implications. In mine planning and design stage, mining method selection (MMS) for a mineral deposit is one of the most critical and challenging decision that experts have to make mainly based on geological, economical and geotechnical properties of the ore deposit.
