Mines in Neath Port Talbot

Neath Port Talbot sits at the western end of the South Wales coalfield, where the coal turns to anthracite — the hardest, cleanest-burning and most awkward coal in Britain to win. The Dulais and Neath valleys were sunk late and deep to reach it, and Cefn Coed at Crynant went deeper than any anthracite mine in the world.
