PROVIDENCE, Ky. — A rescue team found a second Kentucky miner dead Thursday after a roof collapse at an underground coal mine with a long history of safety problems. Kentucky Gov. Steve Beshear identified the miners as Justin Travis, 27, and Michael Carter, 28. The collapse happened late Wednesday at the Dotiki Mine near Providence. "Our entire state mourns along with the families and friends," Beshear said in a statement. "Despite our sadness, we must press forward to the work ahead of us — fully investigating what caused this accident and determining ways to avoid such accidents in the future." Carl Boone, district supervisor for the U.S. Mine Safety and Health Administration, said crews have removed Carter's body from the mine, but, as of 4 p.m. Central, were still working to retrieve the body of Travis. Boone said the investigation into the collapse will begin as soon as it is determined that the mine is safe to enter. "We'll just have to take it one step at a time," he said.
