The accumulation of uncontrolled coal dust in a workplace is a dangerous situation that needs to be eliminated. The control of coal dust can be improved by implementing the use of dust-approved vacuums, dust collection systems, methods to reduce fugitive coal dust, and following general housekeeping procedures.

A video on cleaning dust from workers' clothing. Occupational dust exposure occurs when small particles are generated at the workplace through the disturbance/agitation of rock/mineral, dry grain, timber, fiber, or other material. When these small particles become suspended in the air, they can pose a risk to the health of those who breath in ...
Coal dust is responsible for the respiratory disease known as pneumoconiosis, including coal worker's pneumoconiosis disease that occurs among coal miners. The danger of coal dust resulted in environmental law regulating workplace air quality in some jurisdictions. In addition, if enough coal dust is dispersed within the air in a given area, in ...
Fugitive dust is an environmental air quality term for very small particles suspended in the air, primarily mineral dust that is sourced from the soil of Earth's pedosphere. A significant volume of fugitive dust that is visible from a distance is known as a dust cloud , and a large dust cloud driven by a gust front is known as a dust storm .
Exposure to coal dust is the cause of coalworker's pneumoconiosis, also called "black lung disease", is an interstitial lung disease caused by long-term exposure (over 10 years) to coal dust. Symptoms include shortness of breath and lowered pulmonary function. It can be fatal when advanced.
Damp is the collective name given to all gases (other than air) found in coal mines in Great Britain and North America. [1]As well as firedamp, other damps include blackdamp (nonbreathable mixture of carbon dioxide, water vapour and other gases); whitedamp (carbon monoxide and other gases produced by combustion); poisonous, explosive stinkdamp (hydrogen sulfide), with its characteristic rotten ...
The raw coal is then fed into the pulverizer along with air heated to about 650 °F (340 °C) from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows out the usable fine coal powder to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.
coal dust: 75: The series of coal dust explosions within a mine rocked the close-knit township and was audible as far as 30 kilometres (19 mi) away. Benxihu Colliery explosion: April 26, 1942: Benxi, Liaoning Manchukuo (now China) coal dust and gas: 1,549: 34% of the miners working that day were killed. This is the world's worst-ever coal ...
