Read MoreCaving 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.
