Coal is an important global commodity and will remain so for the foreseeable future. Thus, mining of coal will also remain important. Despite improvements in exposure assessment and ventilation controls and the existence of protective government regulations, coal miners are still at risk for respiratory diseases caused by coal mine dust and their associated morbidity and mortality.

Along with coal worker's pneumoconiosis, also called black lung, silicosis is one of the primary respiratory diseases that has damaged the mining industry since the industrialisation of drilling operations in the 20 th century.. classified as an occupational lung disease, silicosis (which is itself a form of pneumoconiosis) is caused by the inhalation of crystalline silica dust.
Cdc - coal workers' health surveillance program coal . aug 08, 2012 coal mining-related respiratory diseases can affect the gas exchanging tissues of the lungs. these lung tissues remove carbon dioxide and take up oxygen. the diseases can also affect the lung passages that carry air back and forth during breathing. the passages are called airways.
The potential of coal mine dust to cause disabling pneumoconiosis has long been recognised, but research now suggests that pneumoconiosis is not the only respiratory hazard of coal mining. over the last 30 years evidence has accumulated that miners also experience an excess of chronic obstructive pulmonary disease (copd), and this has led the british government to classify chronic bronchitis ...
The disease gets its name because affected lungs appear to be black in colour rather than pink. causes: cwp is caused by prolonged exposure to respirable coal dust. the gradual accumulation of coal dust particles within the fine air passages of the lungs cause layers of coal dust, how much dust was in the air and how long you have been exposed ...
