    74 Mining And Quarrying Ilo Encyclopaedia

    Openings in a block-caving mine are subject to high rock pressure. Drifts and other openings, therefore, are excavated with the smallest possible section. Nevertheless, extensive rock bolting and concrete lining is required to keep the openings intact. Properly applied, block-caving is a low-cost, productive mass mining method.
