Coalworker's pneumoconiosis Wikipedia
Coal workers' pneumoconiosis (CWP), also known as black lung disease or black lung, is caused by long-term exposure to coal dust.It is common in coal miners and others who work with coal. It is similar to both silicosis from inhaling silica dust and asbestos dust. Inhaled coal dust progressively builds up in the lungs and leads to inflammation, fibrosis, and in worse cases, necrosis.
