SHAFT VENTILATION COMPLEX Russian patent published in 2007 - IPC E21F1/08 

FIELD: mining industry, possible use for ventilation of shafts, mines and other underground industrial objects.

SUBSTANCE: invention is a shaft ventilation complex, including forcing system for shaft ventilation, consisting of feeding channel equipped with blade ventilator plant with engine, draining channel, auxiliary channel and main channel connected to the mine, while complex is provided with additional shaft ventilation system, while at least either feeding channel of forcing system or draining channel of additional system is made twin, while main channel of shaft complex is provided with elastic longitudinal wall forming two chambers, one of which is connected to ventilation forcing system, and each draining channel is equipped with ventilation plant, containing axial ventilator with centrally positioned blades and peripherally positioned engine held on internal surface of channel, while ventilators of ventilator plants of feeding channels are axial with centrally positioned engine and peripherally positioned blades, while each ventilator for draining channels is made with greater number of revolutions then ventilators of feeding channels, and also all ventilator plants of complex are made reversible.

EFFECT: increased reliability of technological process passage, increased ventilation efficiency, simplified construction of ventilation plant while simultaneously expanding functional capabilities of shaft ventilation complex.
