Abstract

Large quantities of dust are generated during coal mining and transportation, posing a threat to workers’ health. Therefore, this article conducts a systematic review of the literature on coal mine dedusting. This study examines coal mine dust suppression methods by integrating numerical simulations and experiments, focusing on four aspects: the structural improvement of the dust remover, chemical modification, the optimization of the operating environment, and the ventilation system. The structural improvement of a dust remover primarily involves optimizing the nozzle’s structure and size, particularly the Laval structure. The findings indicate that alterations in the surface structure of the Laval nozzle’s contraction section have minimal effect on the airflow velocity. Chemical modification of the dust remover can enhance the wetting properties of coal dust and includes non-phytochemical and phytochemical modification. Molecular Dynamics (MD) simulations are frequently employed in chemical modification. The optimization of the operating environment for dust removers focuses predominantly on spray pressure optimization.
