sub-level caving Archives - Elexon Mining

02/10/2013  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. In addition to a low unit cost, sub-level caving

What every mining professional needs to know about

Typically, cave mining operational costs are a tenth the cost of conventional underground mining methods. Despite the low operational cost, cave mining is highly capital intensive. This is because a large underground infrastructure platform needs to be established before production can proceed. For example, Codelco, Chile’s state-owned miner, will be investing $5.6 billion to convert the ...
