Mine operations were selected for impact inspections based on specific criteria: poor compliance history, including high numbers of violations or closure orders; indications of operator tactics, such as advance notification of inspections that prevent inspectors from observing violations; frequent hazardous complaints or hotline calls; inadequate workplace examinations; a high number of accidents, injuries or illnesses; fatalities; and adverse conditions such as increased methane liberation, faulty roof conditions and inadequate ventilation.

“Clearly, there are still too many mine operators who have not learned the lessons of Upper Big Branch and continue to put miners’ lives at risk,” said Main. “They don’t yet understand the value of safety in our nation’s mines. That’s got to change. Our mission is to protect miners, and protect them we must.”
