  • Sublevel caving - QueensMineDesignWiki

    - A competent rock mass allows for more drilling and blasting within each stope. This provides good fragmentation and leaves the caving above very coarse. This results in blasted material finer than the cave, making distinction between ore and waste easier. • Steeply dipping orebody: - Keeps the low grade waste further away from the current draw points, keeps dilution low. •Massive deposit: - Need a large footprint to minimi
