  • Block Caving Process Animation - Mining Information

    This video describes the block caving process with 3D animation. 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 over the undercut. The drawbells serve as a place for caving rock to fall into.2015-7-1  Block cave mining is a mass mining method that allows for the bulk mining of large, relatively lower grade, ore bodies.
