Abstract: One of the major challenges facing an underground mine planner is selection of the most appropriate mining method to extract the ore. Sareke Copper ore being flat and tabular favours the application of room-and-pillar and/or stope-and-pillar mining methods. Though these mining methods may be preferred for extracting this ore, a further analysis indicated that geotechnical properties of the hosting rock may not support the suggested excavation sizes. This paper, therefore, investigated the suitability of the above mining methods for extracting this ore. The research found out that due to geotechnical nature of the hosting rock, the pillars would be too big to be economical. It was found out that the suggested excavation size could not stand up on its own without major support. Hence, other mining methods, though expensive when compared with the above two mentioned mining methods, may be more appropriate for extracting the ore.
