Jan 01, 2016· 1. Introduction. During mining of seams of mineral rawmaterial, air is polluted with dust. Dust is moving together with the ventilation air (Bhaskar, 1986) and it settles at the wall and equipment in the excavation (Nawrat et al., 2002, Prostański, 2015).Dust presented in the ventilation air poses a risk to health and it has negative influence on working conditions.
