A coal miner drills a bolt into the ceiling of Murray Energy Corporation’s Century Mine near Beallsville, Ohio to help support the underground tunnel in this undated handout photo obtained by Reuters January 29, 2013. Most coal production comes from the "longwall" but miners also scoop up coal broken loose when digging tunnels. While cities such as Pittsburgh have recovered from the decline of coal and steel, rural areas such as the Ohio Valley have been largely left behind. Four or five mines operate in an area that once had 25, veteran miners say. REUTERS/Murray Energy Corporation/Handout
