Block Caving Mining

Engineering Considerations

Block Caving is a mining method in which ore is allowed to collapse due to its own weight in a controlled fashion into chutes. Block caving is usually used to mine large orebodies that have consistent grade throughout.
A thick block of ore is undercut by removing a slice of ore. The un-supported block of ore breaks and caves under its own weight. The broken ore is drawn off from below as the caved mass falls due to gravity.
