Mine Citations Focus on Ventilation, Fire, Electricity

Chart: Safety Violations, By Mine

Massey has said the monitor bypass was not improper.

Investigators looking into the Upper Big Branch disaster haven't yet determined its cause.

Nonetheless, shortly after the explosion, the federal Mine Safety and Health Administration, known as MSHA, lashed out at Massey, issuing a report saying Upper Big Branch and other company mines had a history of serious safety violations.

In that same briefing paper for President Obama, the agency pointed to methane and coal dust as typical elements in explosions like the one at Upper Big Branch.

Massey, a publicly traded company answerable to stockholders, has maintained that it does not put coal production goals ahead of safety, even commissioning a survey of its miners.

At the same time, the company has clashed with regulators since the blast, challenging MSHA's conduct of the investigation, and suing the agency over its regulation of mine ventilation plans.

More Inspections And Citations, But Miners Still Die

The agency is four years into a more aggressive focus on mine inspections -- adopted after 12 miners died in an explosion at the Sago Mine and a fire at Massey Energy's Aracoma Alma Mine killed two miners. Both accidents happened in West Virginia, in January 2006.

The agency already has the authority to close a mine or a section of mine for imminent harm. The management of the agency needs to make it clear to the inspectors that they have that authority, and they haven't done that.

In the following year, MSHA hired more than 270 new mine inspectors so the agency could perform a required four inspections per year of underground mines.

"That's when they started emphasizing more the ventilation plans that each company files with MSHA," says Bruce Dial, a mining safety consultant and former mine inspector. "So that's why the number of citations has gone up rather significantly."

And while regulators did increase inspections, a Department of Labor audit released in March 2010 found several problems with the way MSHA trains inspectors -- including a charge that some mine inspectors were not getting adequate training.

At Upper Big Branch, federal inspectors spent 180 days last year enforcing safety and health standards. Still, they could not prevent the April 5 explosion.

Spadaro says he believes mine inspectors are doing their jobs, and aim to keep miners safe. But, he says, MSHA has not used its authority to close unsafe mines until problems are corrected.

"The agency already has the authority to close a mine or a section of mine for imminent harm. The management of the agency needs to make it clear to the inspectors that they have that authority, and they haven't done that."

MSHA did not respond to several NPR requests to discuss patterns of violations in underground coal mines.

Ventilation A Growing Challenge

Some mining experts believe ventilation problems will continue to threaten the lives of miners, especially as mines become more productive.

As coal mines have become more complex and covered larger areas, ventilating them has become more challenging.

Says Dial: "You have to travel two or three miles in some of these larger coal mines to get back to where they're mining the coal.

"You have to make sure that the ventilation or the air travels that two or three miles. It's much more difficult, much more complex, to set up a ventilation plan on some of these mines."

About one in 20 citations last year specifically concerned mines' ventilation plans -- detailed strategies that mine operators must develop to keep fresh air moving through underground passages.

Also notable in the NPR analysis was another well known hazard of underground mining -- maintaining strong structures such as a mine's underground roof. Such problems made up about 10 percent of the citations last year.

MSHA said in a statement last month that roof falls "continue to be a leading cause of coal mining fatalities." The agency says 69 miners have died from roof falls since 2000.
