A rescue team found a second Kentucky miner dead today after a roof collapse at coal mine with a long history of safety problems. The two miners, ages 27 and 28, were killed in an accident at the Dotiki Mine near Providence in western Kentucky. They were operating what's known as a continuous miner, a toothy machine that digs coal for transport to the surface, when the roof came down.
The mine is owned by Alliance Resource Partners, based in Tulsa, Oklahoma. The company's website says it purchased the mine in 1971 and produces high-sulfur coal there. State and federal records show more than 40 closure orders for the mine over safety violations since January 2009. (More coal miners stories.)
