Definition of sublevel stoping

Definition of sublevel stoping i In this mining method the ore is excavated in open stopes retreating from one end of the stope toward the other The orebody is developed first by a series of sublevel drifts above the main haulage level The sublevels are connected by a starting raise at one end of the stope and by a passageway raise for...
