FIELD: mining.
SUBSTANCE: method includes use of control devices. At the same time a control device is installed in a blind pit neck in the form of a metal triangular pyramid with gates of louvre type with flow-guiding sections added along with development of the blind pit, which may redistribute and send at any moment of time the required portion of general mine ventilation air for ventilation of the blind pit without installation of an additional source of draught. At the same time gates are moved with a controlled pneumatic drive in a horizontal plane.
EFFECT: higher efficiency of ventilation of underground blind pits.
