Abstract Coal dust explosion constitutes an ever-present hazard in underground coal mines worldwide. This study examines the effects of important parameters, such as, dust particle size, dust concentration and dust-dispersion-air pressure on rock dust inertant requirement for suppressing coal dust explosion using a Godbert-Greenwald (GG) furnace.

Effect of low-concentration coal dust on gas explosion propagation law
Powder Technology, 2020Abstract 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 ...

2010 4th International Conference on Bioinformatics and Biomedical Engineering, 2010 According to characteristics of fully mechanized top-coal caving face and related survey date, a mathematical model of dust movement was derived from gas-solid two-phase flow theory. Numerical simulation of the dust concentration was made with CFD software FLUENT. The result matches well with the related survey date and shows that most of the dust move

Light-Field Microscope Versus Microprojector in Determining Coal Dust Concentrations
American Industrial Hygiene Association Journal, 1967Abstract 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, 1971The 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.
