BACKGROUND Block cave mining is an efficient technique that leverages gravity and induced stress to support the efficient extraction of ore from a rock mass. Block cave mining methods, due to their low operating costs and high productivity, have historically been the preferred underground solution to profitably mine large, low-grade deposits.
