Abstract Detailed characterization of respirable coal mine dust is critical to understanding occupational health outcomes, as well as improving exposure monitoring and dust controls in mines. However, data on characteristics such as particle size and mineralogy are still scarce, and there are virtually no datasets available that allow direct ...

Study on explosion suppression of coal dust with different particle size by shell powder and NaHCO3
Fuel, 2021Abstract In order to improve the pertinence of coal dust explosion suppression technology, a 20 L spherical explosion characteristic test system and a dust minimum ignition energy test device were used to study the suppression differences of different particle sizes of coal dust with inert and active explosion suppressants.

Size Distribution Measurement of Airborne Coal Dust by Optical Particle Counters
American Industrial Hygiene Association Journal, 1974 An optical particle counter has been calibrated for size distribution measurement of airborne coal dust particles. A differential electrical mobility analyzer was used with a fluidized bed dust feeder to produce uniform coal dust particles of a known size for calibration for particles

Journal of Cleaner Production, 2020
Abstract Respiratory dust and dust fall from the mechanized excavation faces of coal mines are crucial issues that require immediate attention. The dust fall technique for two-phase gas–water spraying is effective in solving these issues. We designed a spray dust fall simulated experimental system to test the dust fall efficiency for six grain sizes ...

The effect of coal particle size on colorimetric analysis of roadway dust
Journal of Loss Prevention in the Process Industries, 2001 Colorimetric 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 ...

Effects of particle size on the self-ignition behaviour of a coal dust layer on a hot plate
Fuel, 2019 Abstract Knowing the sizes of coal particles is vital for understanding the real ignition behaviour of coal dust deposits on a hot plate. Furthermore, such knowledge facilitates model construction for assessing industrial coal dust explosion risk. Three particle sizes (0.10–0.15, 0.15–0.20, and 0.20–0.30 mm) of coal samples were selected to analyse ...

Applied Industrial Hygiene, 1986 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 ...
