Abstract
Annotation. The flow rate of mine main ventilation fans is spent on ventilation of all cleaning and preparation faces ∑Qz; on short currents arising between the fan channel and the outside atmosphere - external leakages; on countless short currents arising in underground workings through leakages in ventilation structures, coal pillars and mined-out space - internal leakages, as well as on ventilation of machine and other chambers that need separate ventilation.
