FIELD: mining.
SUBSTANCE: invention relates to the field of mining and can be used in underground mining to ventilate the workings of mines and mines. The device for ventilation of dead-end mine workings includes a main pipeline stretched in the main working, a suction pipeline placed in the dead-end working and connected to the main pipeline, a fan connected to the end of the main pipeline. The device is equipped with gas and dust control sensors located at the inlet of the suction pipeline, and automatic fan on/off equipment associated with gas and dust control sensors. At the same time, the main pipeline is made along the length with windows closed by covers and stretched along the entire length of the main working, the suction pipeline is connected to the main pipeline through one of the windows with the cover removed, the fan is installed at the outlet of the main pipeline and is connected to the ventilation opening.
EFFECT: improving the safety and productivity of work performed in mine workings.
