Health and safety effects of dust. From 1 November 2018, the occupational exposure limit (OEL) for respirable dust at coal mines is /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;

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.

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
COAL DUST EXPLOSION HAZARDS by CLETE R.

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 mine production of more than 1 billion in 2014.
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 coal mines in MSHA''s ten bituminous coal mine health and safety districts (see figure 1). (MSHA

Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.

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 mining industry desperately seeking answers. The pioneering work of Taffanel in France and Rice in the convinced the mining industry of the dangers of coal dust.
Given the results of the recent coal dust particle size survey and largescale 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 .

In the United States, current rock dusting requirements remained largely unchanged since 1969. US Title 30 Code of Federal Regulations Section is based on a coal dust particle size survey performed in the 1920s and later was supplemented by fullscale 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 reexamined through largescale explosion tests."
This NIOSH report presents the results of extensive inmine coal dust particle size surveys of dust samples collected from intake airways in 61 coal mines, representing all 10 MSHA bituminous Coal Mine Safety and Health Districts.
