Coal dust is made of carboncontaining particles, and coal miners are at risk of inhaling this dust. Coal miners may also be exposed to silicacontaining dust because coal mining may involve some drilling into silicacontaining rock. Workers exposed to graphite dust can also develop pneumoconiosis similar to CWP.

It is unclear whether CWP predisposes miners to developing RA, whether RA takes on a unique form in patients with CWP, or whether RA alters the response of miners to coal dust. Multiple rounded nodules in the lung appearing over a relatively short time (Caplan syndrome) represent an immunopathologic response related to rheumatoid diathesis.

Coal workers'' pneumoconiosis (CWP), also known as black lung disease or black lung, is caused by longterm exposure to coal 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 .
