| Administrative History | Exploratory shafts at Grassmoor were first sunk by Alfred Barnes in 1846. The mineral rights for the coal seams were leased from the Duke of Devonshire. By 1861, these shafts had worked enough coal to fund further sinking to the Blackshale seam. The other seams worked were the Tupton, 1st Piper, 2nd Piper, Deep Hard, Deep Soft and Waterloo coal seams.
The colliery was transferred to the National Coal Board as a result of the nationalisation of the coal industry in 1947., when it was put into the East Midlands Division Area No. 1. The colliery was officially closed in August 1950. The remaining men working here were transferred over to Williamthorpe, as the workings became merged underground. This meant coal was still being produced from near Grassmoor until around 1960. Due to this, the site continued to be administered as a separate unit until 1967. From 1957 a National Coal Board training centre was established for miners at the Grassmoor colliery site, using the exisiting facilities still available. |
