Aldwarke main Colliery

Aldwarke Main Colliery was a coal mine sunk in the Don Valley, near Rotherham, South Yorkshire.

The colliery was sunk in three stages, first to the depth of the productive Barnsley seam (bed) in 1867. It took a further 10 years to reach the Parkgate bed and it was not until 1884 that the Silkstone seam was reached. The colliery continued taking production from these seams until the Second World War when, between 1944 and 1946, the shafts were deepened to reach the Swallow Wood seam and give better access to the Parkgate seam. Ownership was in the hands of Sheffield steelmakers John Brown and Co. Ltd. and passed to the National Coal Board on nationalisation in 1947.
