Respiratory Diseases Caused by Coal Mine Dust

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.

COAL EXTRACTION AND PROCESSING

COAL EXTRACTION AND PROCESSING

To to generate electricity coal is first burned inside a power plant and the heat generated by the coal is then used to heat water. After the water is heated it produces pressurized steam which is channeled through a turbine. As the steam is sent into the turbine it is forced to rotate and this rotation generates electricity. Coal is also used in the creation of materials such as steel. Steel ...

Coal mining

Coal mining

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit ...
