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
