Photograph of Kellingley deep mine
With reserves of around 50 million tonnes, Kellingley Colliery, located at Knottingley, West Yorkshire is the largest remaining deep mine in Yorkshire, currently employing around 550 people.
Exploratory boreholes sunk in the 1950s established up to seven workable seams of coal and the colliery, strategically located in the heart of a network of power stations, began production in April 1965.
The two main shafts are each almost 800 metres deep: the No 1 shaft (791m) is used for the conveyance of men and materials and the No 2 upcast shaft (768m) is used for the conveyance of mineral at the rate of up to 900 tonnes an hour, currently extracted from the Silkstone seam some 660 metres below ground.
As well as supplying local power stations, Kellingley produces much sought after housecoal qualities. Investment plans include new roadways to gain access and open up new coal faces in the Beeston seam south and east of the current workings being developed at a cost of around £55 million.
Annual output for 2007 = 1.8 Million tonnes.
