  • How are diamonds mined by Petra?

    Cave mining (both block caving and sublevel caving), which is currently used at Petra's underground mines in South Africa is a wellestablished and safe mechanised mining method that was first introduced at Kimberley, South Africa in 1951. It is now used extensively as an underground mining method as it allows for the bulk mining of large orebodies and enables a .

  • Mining Levels: Stations, Drifts, Crosscuts

     · Where block caving is the mining method employed haulage levels generally are loed to come under or near the bottom of the ore body, and in modern practice high columns of ore up to 300 feet or more are undercut and caved in one lift. Opening of grizzly and undercutting levels above the main level is a part of stope development that will be discussed later.

  • Underground Sublevel Caving Recommences at Big Bell

    The last phase of underground mining at Big Bell (until 2003) applied a sublevel cave mining methodology with extraction sequencing from the edges, retreating from either ends to the centre. Whilst this proved a very effective and lowcost method, it induced substantial geotechnical stress in the shrinking central pillars
