FIELD: mining industry. SUBSTANCE: according to method, installed in wall of mine head-gear is mixing chamber of ejection ventilating unit with its outlet end directed to atmosphere. Supplied to nozzle of ejection ventilating unit is air outcoming from main shaft ventilating unit. Inleaking air from mine head-gear is removed by ejection through ejection ventilating unit. This reduces external leakage of air, ensures delivery of air into mine in amount equal to capacity of main ventilating unit, cuts power consumption for ventilation of mine. EFFECT: high efficiency. 1 dwg
