Mining continues upwards towards the sur-face until the orebody is depleted. Sublevel 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.
