Hello everyone - I'm well chuffed to have found this forum, and after lurking for a while I thought it was time to contribute.
There's not much about Shropshire mining on the web, despite the pioneering role the county played in the coal industry (longwall used to be commonly known as "the Shropshire Way'".
Alverley.
Alveley is the proper spelling for anyone trying to find more info
Bayton No6.
I've never heard of this one - does anyone know anything about it?
Kemberton:
Connected underground to the neighbouring Halesfield pit at the beginning of/just before WWII. The Halesfield shafts then became the upcast and second means of egress, with all winding of men, materials and coal via Kemberton. After Nationalisation they were referred to jointly as "Madeley Wood Colliery" after the company that had previously owned them. Confusingly, the area known as "Madeley Wood" is actually a couple of miles down the road. Closed 1967 - the area is now an industrial estate, but the former Kemberton offices and canteen/baths can still be seen. The winding house was demolished several years ago in an act of vandalism sanctioned by the morons at our local council...
Grange/Granville.
Like Halesfield/Kemberton, these two pits were joined and worked as one after 1952, with The Grange becoming the upcast/second means of egress. Both belonged to the Lilleshall Co. pre-nationalisation - Granville (one of the titles of the Leveson-Gower family, Dukes of Sutherland, founders of the company) was previously known as "Lilleshall Colliery". The last deep mine in Shropshire, Granville closed on August 25th 1979.
Halesford.
("Halesfield" corr. spelling)
Highley.
Closed 1968
John's original list doesn't mention Ifton Colliery, near Oswestry in the Northwest of the county. Once the biggest pit in Shropshire, it closed (IIRC) in 1968.
