2021-6-15  Block caving mining method is one of the most viable and preferred mass underground mining methods for low grade orebody. However, in combined surface and underground mining, the breakthrough of an underground caving under an open pit may result in subsidence at the bottom of the pit. This can pose a serious threat for the stability of the pit and the safety of the mining. In order to

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.

The Block Cave Mining Method - UK Essays UKEssays

1.1 Block Caving. Block caving is an underground mining method applicable to the extraction of low-grade, massive ore bodies with the following characteristics: large vertical and horizontal dimensions, a rock mass that will break into pieces of manageable size, and. a surface that is allowed to subside. These rather unique conditions limit ...
