FILE – This Oct. 17, 2014 file photo made from Black Mountain in Lynch, Ky., shows an unreclaimed strip mine in Virginia, just across the state line from Kentucky’s Harlan County. Kentucky coal miners bled and died to unionize. The union era’s death knell sounded in Kentucky on Dec. 31, 2014, when Patriot Coal announced the closing of its Highland Mine.
