Block caving | Britannica

In mining: Mining massive deposits for such deposits is called panel/block caving. It is used under the following conditions: (1) large ore bodies of steep dip, (2) massive ore bodies of large vertical extension, (3) rock that will cave and break into manageable fragments, and (4) surface that permits subsidence.
