Sublevel Mining Equipment -
In Sublevel Caving, mining starts at the top of the orebody and develops downwards. Ore is mined from sublevels spaced at regular intervals throughout the deposit. A series of ring patterns is drilled and blasted from each sublevel, and broken ore is mucked out after each blast. Sublevel Caving can be used in orebodies with very different

Forefront Archives - International Mining
2020-4-10HEX-RITE was initially designed to be used in block-cave mines. In the block-caving mining method, the orebody is undercut so the base of the orebody starts collapsing, or caving, due to the mass of overlying material. The orebody subsides under gravity, gathering at draw points for collection and, later, processing.
