"Black Lung Surges Back in Coal Country"

"PRESTONSBURG, Ky. — Ray Marcum bears the marks of a bygone era of coal mining. At 83, his voice is raspy, his eastern Kentucky accent thick and his forearms leathery. A black pouch of Stoker's 24C chewing tobacco pokes out of the back pocket of his jeans. "I started chewing in the mines to keep the coal dust out of my mouth," he says.

Plenty of that dust still found its way to his lungs. For the past 30 years, he's gotten a monthly check to compensate him for the disease that steals his breath — the old bane of miners known as black lung.

In mid-century, when Marcum worked, dust filled the mines, largely uncontrolled. Almost half of miners who worked at least 25 years contracted the disease. Amid strikes throughout the West Virginia coalfields, Congress made a promise in 1969: Mining companies would have to keep dust levels down, and black lung would be virtually eradicated."
