Cave Mining Techniques

Cave mining techniques are the most popular methods for exploiting massive orebodies deep within the earth. In general, cave mining refers to all underground mining techniques in which the orebody is ‘undercut’ or drilled beneath the surface and is recovered as it falls.

Block caving: A new mining method arises | Geoengineer.org

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.

Sublevel Caving - Oraee

Caving Mining Methods. Generally, caving methods extract ore, using the principle of fracturing the ore body and the rocks around it, inducing breaks in the whole strata and hence drawing the manageable ore, under more or less controlled conditions. There should therefore be no drilling and blasting, cutting or ploughing required.
