mining equipment and technology used in block caving

Bulk mining methods . Block caving is used to mine massive steeply dipping orebodies typically low grade with high friability. An undercut with haulage access is driven under the orebody, with "drawbells" excavated between the top of the haulage level and the bottom of the undercut. The drawbells serve as a place for caving rock to fall into.
