| Summary : Sunk between 1924-6 as an outlying shaft of Stafford Colliery, Trentham was redeveloped as a drift mine in the 1970s. It was also known as Hem Heath Colliery. The colliery closed in 1993 and nothing now survives, the site having been redeveloped. Known locally as the `Big A' from its distinctive headgear. It was completely modernised in the 1950s-60s, and became Staffordshire's largest producing pit when it was linked underground to Florence Colliery and a new drift was dug in 1977-8. |
