The effect of coal particle size on colorimetric analysis of roadway dust
Journal of Loss Prevention in the Process Industries, 2001Colorimetric analysis of roadway dust is currently a method for monitoring the incombustible content of mine roadways within Australian underground coal mines. To test the accuracy of this method, and to eliminate errors of judgement introduced by human operators in the analysis procedure, a number of samples were tested using scanning software to ...

The influence of high-voltage and coal dust particle size distribution on dust collecting efficiency
2010 2nd International Conference on Industrial and Information Systems, 2010The working efficiency of electrostatic precipitator can be affected by many factors, and the dust particle size is one of the important factors. The coal dust is used to subject investigated in this test, Dust particle size distribution is tested through experiment combining the theories foundation of the dust particle charge, and the relation between

SummaryFlash fires and explosions in areas containing an enriched combustible dust atmosphere are a major safety concern in industrial processing. An experimental study was conducted to analyse the effects of atmospheric coal dust particle sizes and concentrations on the minimum auto‐ignition temperature (MAIT) of a dust cloud.

Particle-size effects on the distribution of fuel nitrogen in one-dimensional coal-dust flames
Symposium (International) on Combustion, 1988Measurements of the distrubution of fuel nitrogen as a function of residence time in fuel-rich, one-dimensional, bituminous, pulverized-coal/O2/Ar flames are reported. A complete accounting of the major nitrogen-containing species, HCN, NO, NH3, N2, and solid-phase nitrogen, was obtained for three different particle size distributions.

The Annals of Occupational Hygiene, 1988
Abstract In addition to mineral composition, various other factors influence the pathogenicity of the coal mine dusts. The grain size distribution of the dusts indicates the depth of deposition of dusts in the alveolar region. Thus there may arise the question of the severity of the health hazards caused by every particle size.

Abstract Exposure to airborne dust in coal mines has caused respiratory disease in coal miners. The causal agent in these diseases remains unknown, although the minerals found in and around the coal seam have been implicated. Toxicological studies designed to establish the effect of different mineral combinations and concentrations are lacking because ...

For the past 3 years the Bureau of Mines, Avondale Research Center, has been doing extensive particle size measurements on respirable coal dust collected at surface and underground mines in the eastern United States. Respirable dust is the portion of airborne dust that penetrates the deepest portion of the lungs and is generally considered to be ...
