sublevel caving mining method

Cave Mining Today's Challenges SRK

Apr 08 2016· The industry perception is that sublevel caving is a "dirty mining method" (ie high dilution and low recovery) However there were several successful sublevel cave mines executed in the past The success of a sublevel cave mine is not by chance they are engineered to perform
