The wall caving is induced by mining the ore in controlled sequence, usually from hanging wall to footwall and from top to bottom. Sublevel caving is often used in conjunction with surface mining. Sublevel caving extracts the ore via sublevels, which are developed in the orebody at regular vertical spacing.
