Report: Coal dust from active mines is more toxic, but mining inspectors fail to sanction coal mine owners

Despite increasing rates and severity of black lung disease in Appalachia, coal mining operators continue to avoid U.S. Mine Safety and Health Administration harsh consequences meant to protect coal miners from toxic levels of coal dust and its more lethal counterpart, silica, report Michael D. Sallah, Jimmy Cloutier and Mike Wereschagin of the Pittsburgh Post-Gazette.

MSHA inspectors have repeatedly documented "dangerous levels of dust spewing in the mines — conditions that can prompt a temporary shutdown of an underground workplace — but failed to impose any penalties, only to find the companies violating the same thresholds again," the Post-Gazette reports.

When black lung disease began surging in 2009, the MSHA launched a campaign to clamp down on coal operators, but critics say the stricter sanctions on mine owners have not produced safer work conditions for miners.

If anything, mining is more deadly for workers who have to drill deep into silica-producing sandstone and limestone to reach coal beds. The Post-Gazette reports, "Fine particles of silica cut into the lungs, creating deep scars and inflammation, forcing the patients to use oxygen and eventually choking off their ability to breathe."

The impact of silica on today's coal miners is startling. Sallah writes, "In central Appalachia, one in every five people who have worked in the mines for at least 25 years is suffering from black lung disease."

Equally troubling is how many active mines ignore regulations and escape enforcement. "Hundreds of coal dust samples pulled from mines since 2014 were found to be breaking the limits without any disciplinary action taken by MSHA," the Post-Gazette reports.

Coal operators could lessen dust exposure, but those changes to ventilation and processes would cost "roughly $100 million a year," the report explains. 

Mine operators continue to push for their right to choose how they protect workers from coal dust.
Over the past year, one mine in Kentucky "showed a silica level eight times the safety threshold," the Post-Gazette reports. "In West Virginia last year, the level was six times over the limit."
