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.

Breathing in coal dust causes coalworker's pneumoconiosis or "black lung", so called because the coal dust literally turns the lungs black. [137] In the US alone, it is estimated that 1,500 former employees of the coal industry die every year from the effects of breathing in coal mine dust. [138]
Photomicrograph made with a scanning electron microscope and back-scatter detector: cross section of fly ash particles. Fly ash, flue ash, coal ash, or pulverised fuel ash (in the UK)—plurale tantum: coal combustion residuals (CCRs)—is a coal combustion product that is composed of the particulates that are driven out of coal-fired boilers together with the flue gases.
In occupational settings, extremely small dust particles are sometimes referred to as particulates, or particulate matter when referring to certain sizes of particles in the ranges of 10 um, 2.5 um, 0.1 um, etc. Suspended dust in the air can also be referred to as an "aerosol" or "particulate aerosol", though "aerosol" is a broad term that ...
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 ...
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.
Though bituminous coal varies in its chemical composition, a typical composition is about 84.4% carbon, 5.4% hydrogen, 6.7% oxygen, 1.7% nitrogen, and 1.8% sulfur, on a weight basis. [11] Its bank density (the density of a coal seam prior to breaking up during mining) is about 1346 kg/m 3 (84 lb/ft 3) while the bulk density of extracted coal is ...
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 ...
