A coal miner has been killed in an equipment accident in Letcher County. The accident was at the Hubble Mining Company’s Number 9 mine at Eolia in Letcher County, and 47-year-old Jerry Britton of Pound, Virginia was killed when he was hit by a personnel carrier.Since Hubble Mining Company took over the mine in August of 2010, the facility has been cited nearly 60 times by the federal Mine Safety and Health Administration. One-third of those violations were categorized as “significant and substantial” by the agency, which means there’s a reasonable likelihood the violation will result in injury or death. The state and federal mine safety offices will investigate the accident. Britton's death marks Kentucky’s seventh mining fatality this year.
