The reason for the increase? As the large coal seams get tapped out, miners are now busting through thicker rock layers to reach ever-thinner layers of coal. This means far more dust circulating in the air—so much so that the filters in respirators intended to protect miners are quickly clogged with dust.
“One of the turns of phrase I hear a lot is, ‘You can’t see your hand in front of your face,’” said Willie Dodson, the Central Appalachian Field Coordinator for the environmental nonprofit Appalachian Voices.
Also known as coal worker’s pneumoconiosis, black lung affects roughly 16% of coal miners, according to the American Lung Association. The tiny particles of crystalline silica released by mining are easily inhaled deep into the lungs, where they embed in and inflame the alveoli, causing swelling, fibrosis, and scar tissue nodules. In the early stages, the disease may have no symptoms, but it eventually causes shortness of breath, chest tightness, and coughing. As it worsens, black lung can lead to low blood oxygen levels, straining the heart. The disease is linked to an increased risk of early death.
“It’s very common for folks in the coalfields to talk about how awful it was to watch their dad’s or granddad’s breathing get worse and worse until they are just laid up gasping and ultimately suffocate,” Dodson shared.
Silica standards are outdated, advocates say
Despite heightened levels of silica dust exposure from modern mining methods, the silica standard—the permissible exposure limit set by the US Mine Safety and Health Administration—hasn’t changed since 1985. It no longer matches stricter standards followed in other industries. A proposed rule announced on June 30, 2023, would toughen the standard, but advocates note that it’s far from perfect, with unclear language around enforcement mechanisms.
Another big issue: If a miner is diagnosed with black lung, they can apply for compensation and medical care via the Black Lung Program. The problem? The application process is cumbersome and outdated, and attorneys who can help are hard to find, advocates say.
“Less than a third of miners who apply ultimately receive benefits. And many more miners never bother applying because they’ve heard how difficult the process is from friends and colleagues who’ve attempted [to do so],” wrote Quenton King of Appalachian Voices in a blog post on two proposed bills now being considered by Congress.
The federal Relief for Survivors of Miners Act, introduced to the US House of Representatives in December 2023, aims to simplify the application process for miners and widows.
