Block caving mining method with Elfen software, explained ...

Block caving is a mining method that relies upon natural forces to break the rock. The cave is initiated by an undercut where a large area beneath the mining block is removed; gravity induced stresses then develop within the rock, causing it to fracture. The fracturing process is progressive and affects the entire rock mass overlying the undercut.

Block caving: A new mining method arises Geoengineer.org

Block caving is a new alternative method of developing new mines or extending the operation of open pits. 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.

Cave Mining Techniques. 7/6/2012 Block caving is a large-scale mining method that is particularly useful for mining low-grade or disseminated ore bodies which are at too great a depth to be exploited through open-cast mining. This mining technique gets its name from the layout of the mine which divides the ore into large sections or ‘blocks’.
