  • Mining Methods Block Caving  Geology for Investors</a></h4>WHY USE BLOCK CAVING?Block (gravity) caving is a bulk underground mining method, which allows large lowgrade 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. It is a useful technique to extend the life of large deposits previously mined by open pits, and it is a method increasingly proposed for new mines around the world.
