Coal worker pneumoconiosis results from the inhalation of dust generated by the drilling, blasting, or crushing of coal and by the equipment and processes used to extract coal. Exposures in coal mining are heterogenous, which contributes to a wide spectrum of disease in coal miners. The clinical manifestations of coal worker pneumoconiosis ...Web

Pneumoconiosis. The term 'pneumoconiosis' refers to a group of lung diseases caused by the inhalation - and retention in the lungs - of dusts. The most commonly occurring types of pneumoconiosis (apart from asbestosis) are coal worker's pneumoconiosis, arising from the inhalation of coal dust, and silicosis, arising from the inhalation of ...Web

Legislation signed by President Ronald Reagan in 1981 removed presumptions that assumed if a coal miner had worked a set number of years in an underground coal mine and was "totally disabled" by pulmonary or respiratory issues but had not technically been diagnosed with black lung, also known as coal miner's pneumoconiosis, the …Web

In simple coal workers' pneumoconiosis, coal dust collects around the small airways (bronchioles) of the lungs. Every year, 1 to 2% of people with simple coal workers' pneumoconiosis develop a more serious form of the disease called progressive massive fibrosis, in which large scars (at least ½ inch [about 1.3 centimeters] in diameter) develop …Web

CWP occurs in two forms: simple and complicated (also called progressive massive fibrosis, or PMF). Your risk for developing CWP depends on how long you have been around coal dust. Most people with this disease are older than 50. Smoking does not increase your risk for developing this disease, but it may have an added harmful effect on the lungs.Web
