block caving copper mining


About the Project - Resolution Copper

Resolution Copper is working with regulators and the community to develop one of the world's largest untapped deposits of copper. The Resolution Copper deposit lies more than a mile beneath the surface and the most viable way to recover the Resolution resource is by going underground, using a process called block caving.

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.
