An account is given of longwall mining in the Sydney Coalfield, Nova Scotia where the majority of the workings are under the sea-bed. Longwall faces 700 ft in length are being worked with a 200 ft coal pillar left between adjacent panels. Extraction is of the order of 60%. Face machinery, manpower and production are described. In future it is hoped that some retreat working will be used.
