Study and evaluation of the stability of underground mining method used in shallow-dip vein deposits hosted in poor quality rock

Purpose.This article proposes to analyze and determine the mining design for shallow-dip deposits hosted in poor quality rock. Methods. We used UBC tool find optimal exploitation method, Rock mass rating (RMR) Q-system (Q) stope recommended rock support, numerical modeling by RS2 software with a variety of geotechnical, geometrical, technical conditions evolution unstable zone width maximum total displacement around after excavation. Findings. The optimum method designated this type deposit is cut fill. By projecting obtained RMR values on graph, it concluded that operating located stable height 3 m, bolting support recommended. simulation reveals can be mine vein rocks consists m high 75° dip cemented backfill. Originality.This work presents study choose most suitable underground Practical implications.In industry, success an conditioned selection appropriate dimensioning adapted nature rock, excavation geometry according deposit.
