Types of Underground Mining Method Comparison

Caving Methods of Mining There are three distinctive methods of working large deposits that involve, in some way, the factor of caving. Slightly different names are in use, but those that are simple as well as descriptive are top slicing, sublevel caving, and block caving.

Sublevel caving - ScienceDirect

This characteristic interplay of forces can create suitable conditions for sublevel caving even at greater mining depths below ground level. The formulae quoted above for the approximate calculation of the parameters of sublevel caving or front caving can be applied for mining descending from foot wall to hanging or vice versa.
