FIELD: tertiary oil recovery, particular, mine recovery of oil with use of heat in development of oil pools with high-viscosity oils and movable bitumens. SUBSTANCE: series of underground mine workings are driven. Drilled from working gallery are injection and producing holes. Initial production rate of producing holes are determined. Holes with maximum production rate are closed, and heat carrier is injected into injection holes. Upon attainment of production rate equalling maximum value of each separate holes and by all producing holes, all holes are operated with maximum possible time of operation up to attaining the design recovery of oil of the district. EFFECT: higher efficiency.
