FIELD: ventilation.
SUBSTANCE: method is carried out by performing a regulating device in the form of a pipeline with a fork, at the entrance of which a fan is installed. The pipeline is branched to a vent pipeline, the free end of which leads into a blind working and to the discharge pipeline located in the air-supplying drift. Using a flow sensor, the amount of air entering the vent pipeline is monitored. The volume of air supplied through the vent line to the blind working is regulated by the adjustable damper installed on the discharge line.
EFFECT: efficiency of ventilation of the blind working.
