OIL MINE SLOPE UNIT VENTILATION SYSTEM Russian patent published in 2018 - IPC E21F1/08 E21F17/18 

FIELD: mining.

SUBSTANCE: invention relates to the mining industry and can be used for inclined blocks ventilating in fields of high viscosity oil and natural bitumen, the underground mining of which is carried out by the mine method using thermal methods of impact on the formation. Oil-well gradient unit ventilation system includes a surface fan and a deflector located on the oil well ventilation well, a microcontroller unit connected to air temperature and pressure sensors or densitometers, as well as with air flow sensors located in the air supply and air outlet passages of the slope unit, a local ventilation fan with a control unit located in the air supply passage, as well as an air lock in the air discharge passage. In the drilling gallery and air lock there is for the presence / absence of miners controlling device, in front of the air lock at the mouth of the ventilation well there is a locking element with a control unit, the surface fan is equipped with a control unit. At that, the local ventilation fan, the shut-off element, the surface fan, and the miner's presence/absence monitoring device control units are connected to the UMC, which is capable of processing signals coming from said units, specified sensors and a presence/absence of miners monitoring device, issuing control signals for changing the locking element operating modes, as well as the ability to control the local ventilation fan, surface fan and the main fan installation, depending on the presence/absence of miners in the drilling gallery and air lock.

EFFECT: technical result consists in reducing the energy consumption for ventilating the slope unit by adjusting the volume of air necessary for supply to the oil mine, depending on the presence/absence of miners in the drilling gallery and air lock.
