Tehkompleks ground equipment comprises wellheads 1, drilling units 2, 3, for sinking boreholes 1, 4 and 5 the formation of openings in the reservoir 6; units 7, 8 for the enrichment and classifying the produced mineral, which is as iron; complex also contains several types of autonomous drilling apparatus that are used for sinking boreholes, to form openings in the productive layer structure, and for lifting of the mineral to the surface. The device 3 comprises a gas generator 9 to the hydrogen-oxygen fuel composition with the initiator 10 and the gassing nozzles 11 for supplying an excess of hydrogen in the drill cuttings weight bearing iron ores. Apparatus 12 comprises a gas generator 13 for removal of the drill cuttings toward the mouth of wells 4, and subsequent removal of the sludge on the process fractionation, classification and beneficiation. Such technological mineral extraction circuit can reduce the development costs of ore, its rise to the surface and isolation of useful material. IL. - 3; 3 z.p.f.
