Sublevel Caving Mining Method

  • Underground Mining Methods — New Pacific Metals

    Block Caving. Block caving is essentially the underground version of open-pit mining. It's the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.
