Nearly three years after a deadly mine explosion in West Virginia, a former Massey Energy mine superintendent has been sentenced to prison and federal regulators have toughened a regulation that could have helped prevent the disaster.
Federal prosecutors in West Virginia stepped higher up the corporate ladder at Massey Energy Wednesday with new criminal charges stemming from the investigation of the 2010 coal mine explosion that killed 29 workers.
David C. Hughart was president of Massey's Green Valley Resource Group, a major coal mining subsidiary based in Leivasy, W. Va., from 2000 to 2010.
Federal regulators have announced the results of a September inspection blitz targeting 13 coal mines in seven states "previously cited for violations regarding respirable dust sampling ... inadequate dust control ... and hazard complaints" involving excessive coal dust.
