On the other hand, if a stope is well defined and long enough, the access is developed in the middle of the ore block, perpendicular to it. This way, two mining faces are available. Once the ore is reached, a first cut is excavated by sub-drifting up to the width of the ore. The next step is to backfill the opening.
