Determination of the value of air reserve coefficients in coal mines

Abstract
The flow rate of mine main ventilation fans is spent on ventilation of all stoping and development faces ∑Qz; on short circuits arising between the fan channel and the outside atmosphere – external leakages; on countless short circuits 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.
