Marine Colliery was opened in 1893 by the Ebbw Vale Steel, Iron and Coal Company Ltd. In 1913 there were 2,407 men employed. By 1935 ownership changed to Partridge, Jones & John Paton Ltd. who worked the colliery until Nationalisation in 1947.

During the 1970's marine Colliery was integrated underground with Six Bells Colliery, all the coal being handled at Marine Colliery.

Marine Colliery was the last deep mine to work in the Ebbw valleys and closed in March 1989. Its tips now largely removed or landscaped.
