    Introduction. Coal workers pneumoconiosis, better known as CWP or black lung disease, can be defined as the accumulation of coal dust in the lungs and the tissue's reaction to its presence. Inhaled coal dust progressively builds up in the lungs and is unable to be removed by the body; it leads to inflammation, and fibrosis, and in the worst case necrosis.
