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.
