  • Block caving - QueensMineDesignWiki

    Block caving. Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping ore bodies located at depth. These ore bodies are generally low grade in nature and are too deep to be extracted through open pit mining. The technique is commonly used to extract low grade copper, copper-gold, iron and molybdenum ...
