That's according to a regulator in Illinois, where no coal miner has died on the job for two straight years for the first time in 123 years.
Mike Woods is the supervisor of mine safety and training for the state's Office of Mines and Minerals. And he says he feels "very confident" that Illinois' mine-safety efforts work.
Monday's explosion in West Virginia was the nation's deadliest coal mining disaster in more than four years and renewed attention about safety in an inherently dangerous line of work.
Woods' office inspects the dozen underground and six or seven surface mines in Illinois. And he says his office won't be satisfied until the state has zero accidents.
