Sublevel caving: Engineered to Perform

 · Source: Mining Magazine, September 2013. Sub-level caving is a highly efficient, top-down, underground bulk mining method. Recent developments in sub-level cave mining have advanced the understanding of the technique and its production performance, which allow it to now be considered as a highly viable alternative to open stoping and, in some cases, even to block caving.

Petra Diamonds | How are diamonds mined by Petra?

Sub-level caving. This method owes the first part of its name to the fact that work is carried out on intermediate levels (that is, sub-levels) between the main production levels. It follows the same basic principles as the block caving mining method, but the caves are smaller in size and not as long lasting.
