Health and safety effects of dust. From 1 November 2018, the occupational exposure limit (OEL) for respirable dust at coal mines is 2.5mg/m 3. Find out more about the exposure level review. Breathing in dust can result in a range of occupational illnesses and diseases depending on: size of dust particles;
Coal Dust Particle Size Survey of US Mines. 7/1/2007 - Peer reviewed journal articles. Results indicate that particle sizes of mine coal dust in intake airways are finer and would require more incombustible matter to be effectively inerted than the 65% incombustible specified in current regulations. ...
Given the results of the recent coal dust particle size survey and large-scale explosion tests, NIOSH recommends a new standard of 80% TIC be required in the intake airways of bituminous coal mines. The survey results indicate that the current requirement of 80% TIC in .

If it can't be grown, it must be mined...If it was mined, particle size matters. The USGS (United States Geological Survey) Mineral Commodity Survey for 2015 lists more than 90 different minerals from abrasives to zirconium. Of these, 14 have a U.S. mine production of more than $1 billion in 2014.
Nagy, 1981). A recent coal dust particle size survey in dicates that current mining methods generate finer par ticles; therefore, more inert material is required (Sapko et al., 2007). One advantage of the CDEM is that it ac counts for the coal particle size in its determination of explosibility. The CDEM color readout takes the various
This paper presents the results of a recent coal dust particle size survey to determine the range of coal particle sizes found in dust samples collected from intake airways in 50 US coal mines in MSHA's 10 bituminous Coal Mine Safety and Health Districts (see Fig. 1). (MSHA District 1 covers anthracite mines in Pennsylvania, which do not require rock dusting.)

A mere 100 years ago the mining industry, scientific investigators, and a concerned public struggled with the notion that coal dust could lead to mine explosions. A succession of disasters in 1907 left the U.S. mining industry desperately seeking answers. The pioneering work of Taffanel in France and Rice in the U.S. convinced the mining industry of the dangers of coal dust.
The National Institute for Occupational Safety and Health (NIOSH) and the Mine Safety and Health Administration (MSHA) conducted a joint survey to determine the range of coal particle sizes found in dust samples collected from intake airways of US coal mines. The last comprehensive survey of this type was performed in the 1920s.
The results are presented of a recent coal dust particle size survey to determine the range of coal particles sizes found in dust samples collected from intake airways from 47 U.S. coal mines in MSHA's ten bituminous coal mine health and safety districts (see figure 1). (MSHA
In the United States, current rock dusting requirements remained largely unchanged since 1969. US Title 30 Code of Federal Regulations Section 75.403 is based on a coal dust particle size survey performed in the 1920s and later was supplemented by full-scale testing of the rock dust ability to inert a coal dust .
The authors also recommended that, "In view of current results from the NIOSH coal dust particle size survey in US mines and preliminary size analyses of rock dusts, the effect of rock dust particle size in preventing coal flame propagation should be re-examined through large-scale explosion tests."
