Sublevel Caving Mining Method

Sublevel Caving Mining Methods

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 Sublevel Caving In this method the stope is divided into
