Scope and Content Compressor in Temporary Compressor House, Bilston Glen Colliery, Midlothian Bilston Glen Colliery, one of five super-pits opened by the brand new National Coal Board, was begun in 1952. Sinking was completed in 1963 and production peaked in 1970 when a workforce of 2,367 produced 4,000 tons of coal per day. It was closed in 1989. This shows one of the two Series 563 air compressors by Alley and Maclellan of Glasgow. Each is powered by a 200 horsepower electric motor and produces a pressure of 100 pounds per square inch to power machinery around the colliery. Piped steam and compressed air are often used to power coal-mining machinery because it is safer to create power away from coal dust and possible pockets of gas than to risk setting off an explosion with a spark or flame from an engine or motor.
