Miner Stuart Griffin laughs as he leaves the mine after the final shift at the Tower Colliery in Hirwaun, near Merthyr Tydfill on January 25 2008 in Wales, United Kingdom. The Cynon Valley pit is one of the oldest continuously-worked mines in the world and the last deep mine in Wales. Tower is the only colliery within the once-thriving South Wales coalfield to drain all its coal resources and hit the headlines in 1994 when it was subject to a miners buy-out of the deep mine - after it had been closed by the then Conservative Government.
