Sub-level open stoping

In sub-level stoping, the holes are generally just a few meters apart and some of the holes are adjacent to both the foot wall and the hanging wall. If deviation occurs, it causes a decrease in ore recovery, an increased amount of dilution, and less homogenous fragmentation. In the worst case this could result in a freezed blast.What is sub level stoping? – Raiseupwa What is sub level stoping? Sublevel stoping is a mining method in which ore is blasted from different levels of elevation but is removed from one level at the bottom of the mine. Before mining begins, an ore pass is usually drilled from a lower to a higher elevation.
