Cave Mining Cu Au Porphyry. There are over 45 cave mining projects in various stages of studies and development around the world. Cave mining methods will be the underground method of choice in the future. It is only relatively recent that this mass mining method, despite 70 years of use, has begun proving its potential.

Underground mass mining methods present several geotechnical challenges and risks inherent with block cave mining environments. Underground mining methods such as block, panel, and sub level caving continue to be the primary choice for deeply situated massive orebodies, due to the high production rates and low operating costs involved.

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.

The Resolution Copper deposit lies more than a mile beneath the surface. The most viable way to recover this ore body is by going underground, using a process called block caving. Block caving is a proven mining method using advanced technologies.

Block gravity caving is a bulk underground mining method, which allows large low grade deposits to be mined underground. This method involves undermining the orebody to make it collapse under its own weight into a series of chambers from which the ore extracted.

Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.
