Paper: Value-production systems for block caving mines

Abstract: Block caving mines produce the lowest grade ore in the metal mining industry and more than any other, they must begin to focus on producing ‘value’ rather than tonnes. Block caving involves no primary blasting or backfilling, so the first step in reducing operating cost is to improve coarse ore haulage. Batch load–haul–dump ...
