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.

Block caving is technically complex, but it is also one of the safest and most cost-effective methods of mining ore from deep below the ground as it uses the force of gravity. Put simply, a void is created under the ore body, which then collapses gradually under its own weight. The ore passes through ''funnels'' in the rock, known as draw points.
