coal-mining that the villages of the parish grew, and Birchgrove was no exception. Mining played a very important role in the industrial development of the lower Swansea Valley, which was becoming the metallurgical centre of the world. (See History of Swansea.) Coal was replacing wood in the smelting of ores; and it was because of the demand for coal that a pit was sunk in Birchgrove, known as Birchgrove Colliery Company, locally known as the 'Old Pit'. It was situated just below the Birchgrove Post Office. It was sunk in 1845, to a depth of approximately 100 feet. As a result of its prosperity, two further pits were sunk, namely Sisters Pit, and Brothers Pit. Approximately 200 worked at the Old Pit. This involved many new people coming into the area, to work in both mining and the copper industry. The only cultural recreation was a Reading Room, situated near the colliery. It was not used on Sundays, so the people of the village were given permission to use it for Sunday worship. Services were held there according to the Book of Common Prayer of the Church of England (the Church in Wales not being founded until 1920). The services held there were well supported. The Birchgrove Colliery was closed in 1931. There are still relics of Birchgrove's industrial past in the area, The ruins of Scot's pit pump house dominate the lower end of Birchgrove and evidence of mine workings can still be found.
