Block Caving Ground Truth Trekking

Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.

Block Caving RitchieWiki

Block caving is an underground mining method that permits the bulk mining of large, relatively lowgrade bodies of ore. As a sublevel mining process, block caving involves the controlled collapse of ore from under its own weight into chutes or draw points using gravity.
