Abstract

Abstract. Purpose. Conducting a physical experiment to study the intensity of the process of removing coal dust from the coal pile model. Methodology. For the study, a model of a coal pile was created. The air flow acting on the pile model was created by a blower. During the physical experiment under laboratory conditions, the speed of air flow around the coal pile model varied. During the physical experiment, the mass of the extracted dust was determined and the data was recomputed in order to determine the amount of coal dust blown off the unit surface. Photographing of the formed contamination zones near the coal pile model was carried out. Findings. The intensity of the removal of coal dust from the pile model at different airflow velocities is determined. Data have been obtained that make it possible to estimate the intensity of coal dust emission when predicting the level of contamination of working areas at an industrial site. Originality. The intensity of the removal of coal dust from the model of a pile of coal was determined experimentally. Practical value. The results of the laboratory tests can be applied for an expert assessment of the level of contamination of working areas near the piles of coal. The data of the conducted experiments can be used as input data of the forecast models of the OND-86, the Gauss model.
