The South African coal mining industry and its stakeholders acknowledge that effective mine


    The mining of coal is by the "pillar and breast" system. When the gangway and airway have been driven two or three hundred feet chambers are opened at right angles to the airway,these are called "breasts." A narrow tunnel, just wide enough to admit a mine-car track, is driven about fifteen feet, beyond which the breast is opened to its full
