Considerations for Sublevel Open Stoping OneMine

A raise driven either at the end or in the middle of the stope if stope access is from both ends provides a start for opening up a vertical slot across the stope to establish a free or open face for long hole drilling and blasting. Sublevel stoping has proved to be a relatively safe and economical system.

When designing a sublevel stoping production sys tem, it should be kept in mind that production rates from conventional sublevel stopes vary widely through out the life of the stope. Early production is at a low rate, coming only from the drawpoints near the slot, but increases as new drawpoints are reached by the stope
