Study on dust distribution and dust prevention measures in fully mechanized coal face
Meikuang Anquan, 2023 In order to obtain the dust distribution law in the fully mechanized coal face, the distribution of shearer cutting dust and the dust along the working face was studied by numerical simulation and field measurement respectively.

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.
