Coal Mine Dust Exposures and Associated Health Outcomes

2018-11-29  Exposure to Respirable Coal Mine Dust. This document had the following major recommendations: 1. Exposures to respirable coal mine dust should be limited to 1 mg/m3 as a time-weighted average concentration for up to a 10 hour day during a 40 hour work week; 2. Exposures to respirable crystalline silica should be limited to 0.05 mg/m3 as

Emphysema and dust exposure in a group of coal

2020-12-1  The lungs of 450 coal miners who had been studied previously in a long-term epidemiologic project at 24 British mines have been examined post-mortem for signs of dust-related fibrosis and emphysema. Reliable estimates of cumulative (working-life) exposures to respirable mine dust were available for 342 of the men. The relative frequency of emphysema increased with age at death, and

Coal dust exposure reduction using water mist

2018-7-1  The water mist system reduced the respirable coal dust concentration in the range of 72–81% at the coal feeding section of the boiler. The respirable dust concentration reduced from 7.17 mg/m 3 to 1.26 mg/m 3 after the installation of water mist system, which is

CDC Mining Coal Dust Exposure and Mortality

Mortality risk was also associated with coal rank region. Conclusion: There was an increased risk of mortality from IHD associated with cumulative exposure to coal dust, and with coal rank. The effect of coal rank may be due differences in the composition of coal mine dust particulate.

2020-7-1  Coal dust. Coal miners are at risk for respiratory diseases caused by coal mine dust. Inhaled, coal dust remains in the lungs. Long-term exposure can cause coal mine dust lung disease also known as black lung disease. Miners with combined exposures to coal and crystalline silica dust can also get mixed dust pneumoconiosis.

The Danger in Coal Dust Identifying Threats

As part of the 2014 MSHA dust rule, mine operators are required to use this instrument to measure dust exposure in underground coal mining operations to demonstrate compliance with the applicable dust limit. A real-time dust monitor is the first line of defense in preventing long-term health effects.
