FIELD: mining.
SUBSTANCE: proposed method consists in drilling series of parallel alternating wind and product-extraction wells to shale oil deposit, each said well including rock part working from surface to shale oil deposit and shale oil part worked over, mainly, the deposit bottom. Faces of said wells are crossed by crosswise joining well. Note here that rock parts of said wells are cased and cemented. Fusible metal shanks are lowered in shale-oil parts. Device to fix flame source over the shale oil part in lowered in crosswise joint well along with said shank. Ignition source is created at vertical ignition well bottom to set the dependence of fire source countercurrent displacement rate on flow rate of forced air blow. After fire working of crosswise joining well shale oil part blow air is forced into first product extraction well in compliance with relationship fixed at crosswise joining well.
EFFECT: higher efficiency, lower costs.
