ABSTRACT
Analysis of the research results and recommendations for Donbass coal mines shows that using mine ventilation network with vertical mine working for removing outgoing air stream (fresh air supply) within mining allows to reduce considerably the way of air current movement through the ventilation network, to reduce depression of ventilation network, to increase the amount of incoming air, to decrease ventilation loss etc. As a rule, use of such ventilation networks without necessary scientific and economic grounding results in decrease of ventilating efficiency.
