| Summary : Wheep pit to Greenburn Mine. Field investigations in 2000 by English Heritage recorded the fairly well-preserved remains of a stone-built open sided wheel-pit, built to hold a small overshot wheel, probably 2.4 metres in diameter, powering a set of 'jigs' for sorting the crushed ore. The wheel was supplied from the tail race of another wheel (NY 20 SE 37). The structure was built at some point between 1848 and 1861, and is depicted on a schematic plan though to have been made before 1861, which is now held in Cumbria Record Office. A timber shed, whose plan and floor surface can still be identified, covered the machinery. To the south-east, a tip of small fragments of rock represents the waste material from the process. The wheel probably became redundant circa 1885, when work in Engine Shaft ceased, and the components were probably removed for re-use or sale. By 1873, two precipitation tanks stood nearby (NY 20 SE 42), and these may have necessiated the modification or demolition of the shed. The tail-race from the wheel carried the outflow straight to another overshot wheel (NY 20 SE 39). |
More information : Between mid September and late November 2000, English Heritage carried out an analytical field investigation of the surface remains of Greenburn Mine; the survey was requested and partly funded by the landowners, the National Trust (Event record 1335820) (1). The best-preserved building, which comprises an accommodation block, office and workshop (NY 20 SE 9) serves as a parent record for the other components of the complex.
The fairly well-preserved remains of a stone-built open sided wheel-pit, built to hold a small overshot wheel (probably 2.4m or 8 feet in diameter) powering a set of 'jigs' for sorting the crushed ore. The wheel was supplied from the tail race of another wheel (NY 20 SE 37). The structure was built at some point between 1848 and 1861, and is depicted on a schematic plan though to have been made before 1861, which is now held in Cumbria Record Office. A timber shed, whose plan and floor surface can still be identified, covered the machinery. To the south-east, a tip of small fragments of rock represents the waste material from the process. The wheel etc probably became redundant c.1885, when work in Engine Shaft ceased, and the components were probably removed for re-use or sale. By 1873, two precipitation tanks stood nearby (NY 20 SE 42), and these may have necessiated the modification or demolition of the shed.
