Jul 25, 2018· 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.
Without diamond mining there wouldn’t be diamonds so we should at least know some basic facts about 4 commonly used types of diamond mining based on mining techniques: open pit mining, hard-rock mining, alluvial mining, and the marine diamond mining as the latest technique, all of which leave damaging effects on the earth, sometimes irreversible.
