Retracted: Effect of coal dust parameters on gas‐coal dust explosions in pipe networks
Energy Science & Engineering, 2022 To study the effects of particle size of coal dust and mass concentration of coal dust on gas‐coal dust explosions, we conducted sedimentary gas‐coal dust explosion experiments using a pipe network system that included multiple components and individual ...

Coal dust dispersion from a coal storage pile [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2020 Open coal storage piling is considered as pollution concerned activity because when the air is dry and windy, the coal dust can disperse and cover large area causing air pollution. Knowing in advance the concentration and area affected by the coal dust

The Nature of the Variability of Dust Concentrations at the Coal Face [PDF]
Occupational and Environmental Medicine, 1953 It is well known that dust conditions in a coal mine vary from place to place and from time to time. Watson (1949) pointed out that even at one position on a long-wall face the concentration fluctuates wildly from minute to minute and varies even more from day to day, while the two halves of a double-unit face might differ considerably.
