Block caving is a highly resource-efficient method of underground mining, in which large underground ore blocks are cut from beneath, allowing the ore to collapse under its own weight. After collapsing, ore is drawn through drawpoints and conveyed to a crusher. In DOZ block caving, LHD loaders transfer ore slurry into ore passes leading to chutes.
