Mining Methods: Block Caving Geology for Investors

What Is Block Caving?Why Use Block Caving?How Does It Work?Potential ProblemsFurther ReadingBlock (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. 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.

Touted as the deep mining method of the future, block caving is an underground mass-mining method that allows for the bulk extraction of large, relatively lower-grade ore deposits that are vertical in orientation. The method is an attractive alternative when planning to develop a new mine, or to extend the life of an open pit operation.
