systems employed in South Africa in such a case. In ribpillar extraction, a continuous miner machine cuts a roadway up to kilometres in length through the coal and 5 metres in from the edge of the area to be mined. This leaves a 5 meterwide band of coal in the form of a long, isolated rib pillar along one side of the tunnel.
