SYSTEM FOR OIL MINE SLOPING UNIT INSPECTION Russian patent published in 2018 - IPC E21F1/00 

FIELD: ventilation.

SUBSTANCE: invention can be used for economical ventilation of sloping units in the fields of high-viscosity oil and natural bitumen, developed by the thermocontract method. The ventilation system for a sloping oil mine unit including air flow and temperature sensors connected to a microprocessor unit, air supply and air discharge with air vestibules, as well as a source of superheated steam, is provided with a heat pump including a condenser coil located in the air supply condenser channel, and an evaporator coil, located in the air discharge channel. These coils are connected to the compressor, which pumps the heat carrier, and to the controlled throttle, and the ventilation windows of both channels are equipped with controlled louvres. The microprocessor unit is configured to control the flow rate of the superheated steam entering the production oil reservoir, heat pump operation mode and volumetric air flow entering the sloping unit, depending on the readings from the air flow sensor placed in the air supply along the air flow path, as well as the air temperature sensors, located in the air discharge and drilling gallery.

EFFECT: reduced energy costs for ventilation of the oil mine sloping block by reducing energy losses for productive oil reservoir heating.
