Effect of low-concentration coal dust on gas explosion propagation law

Powder Technology, 2020
Abstract In order to study the effect of low-concentration coal dust on gas explosion characteristics and gas propagation law in gas transmission pipelines in the field of gas power generation, a gas explosion experiment with the participation of low-concentration coal dust was performed by using the self-developed experimental system for coal dust ...

The effects of coal dust concentrations and particle sizes on the minimum auto‐ignition temperature of a coal dust cloud

Fire and Materials, 2017
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.

Light-Field Microscope Versus Microprojector in Determining Coal Dust Concentrations

American Industrial Hygiene Association Journal, 1967
Abstract A study was undertaken to statistically compare equivalent area field counts and dust concentrations obtained by using a microprojector and a light-field microscope. This was to test the opinion that the two methods, although allowed by the standard dust counting technique, are not comparable.

Total Dust, Coal, Free Silica, and Trace Metal Concentrations in Bituminous Coal Miners' Lungs

American Industrial Hygiene Association Journal, 1971
The analysis of lung and pulmonary lymph node tissues of bituminous coal miners is a continuing study at the Cincinnati laboratory of the Bureau of Occupational Safety and Health, Public Health Service. Determinations are made for eleven trace elements (Be, Mg, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, and Pb), free silica, and coal, noncoal, and total dust.

Dust concentrations around coal stockpiles

Science of The Total Environment, 1980
Abstract One of the sources of airborne dust from operations at coal terminals is wind erosion of the stockpiles. The condition of the stockpile, whether it is being worked (a live stockpile) or at rest (dead storage), is of prime importance. A further important set of variables is formed by the meteorological conditions.

The Evaluation and Quantification of Respirable Coal and Silica Dust Concentrations: A Task-based Approach

Journal of Occupational and Environmental Hygiene, 2014
Silicosis and coal worker's pneumoconiosis are serious occupational respiratory diseases associated with the coal mining industry and the inhalation of respirable dusts containing crystalline silica. The purpose of this study (funded by the Mine Health and Safety Council of South Africa) was to evaluate the individual contributions of underground coal ...
