NEHL - The Jane Pit was one of the earliest in the Old Etherley portfolio, working the Brockwell Seam from the first half of the 19th century through to circa 1880s. The pit can be seen in more detail on the 1859 Ordnance Survey, featuring a connection to the Stockton & Darlington Railway eastwards. There were 3 rows of coke ovens and what appears to be 3 small reservoirs. The shaft was at the south end of the pit, alongside two small buildings. Pit terraces could be found adjacent which likely supported all the pits in the surrounding area.
