Forty Horse Pit
The Forty Horse Colliery was situated behind what is now the Codnor Gate industrial Estate and was part of the Knowts hall estate.
An article in the Derbyshire Times on 25th January 1930, discussed the working life of former collier Mr Francis Ottewell, who was a former resident of Codnor and spent many years working at Forty Horse pit.
The article confirms that the colliery was named after the 40 horse power steam engine that worked the pit.
Previously it was thought that it was named after 40 ponies that died in the pit, but this is a mistake and confused with an incident that happened at the nearby Butterley Park No.2 pit and documented in Joseph Millot Severn’s book ‘My Village’ a transcript of which can be read by clicking this link.
Further research also confirms that 40 horsepower steam engines were developed by the Butterley Company during the 1830s to compete with similar sized engines manufactured by companies like The Horsley Iron Company.

and Butterley Iron Works to the left. I have named the fields that I know. Also the spoil heap covers three fields called 'Near Pasture', 'Far Pasture' and 'Long Close'.
The pit was sunk by the Butterley company in the 1840s to work two coal seams, the soft coal seam at 5 feet thick and the hard coal seam at 7 to 8 feet thick. It also worked an Ironstone seam, and it was this pit that provided the Ironstone used by the Butterley company to manufacture the arches in the roof of St. Pancras Station in London at a cost of £117,000. When the roof was completed in 1868 it measured 210m long and spanned a gap of some 75m, making it the largest covered space in the world.
Joseph Millott Severn, author of ‘My Village’ worked at the Forty Horse Pit for one and a half years. It was here were he nearly lost his life when a roof collapse knocked him to the floor and completely buried him. He was lucky enough to be able to wriggle free from the debris and escape with only a few cuts and bruises.
The pit closed in the 1890s but the buildings remained in place and were used as central workshops for all the other pits in the area. The shaft was fitted with a fan and acted as a ventilation shaft for High Holborn pit.
Remains of the pit buildings still existed in the 1960s as did the pond that provided water for the steam-winding engine. This was known as ‘Goss pond’ by the locals and if I remember correctly, had an old car dumped in the middle of it. All signs of the buildings and pond were removed when the Codnor Gate industrial estate was built. Gorse bushes grew on the old pit hill, which was planted with hundreds of saplings that have now grown and created lush woodland.
