A method of mineral fuel beneficiation with subsequent delivery to the consumer by pipeline transportation relates fuel and energy complex and can find application in coal and slate energetics. Invention main objective is security of solid fuel delivery from mine (or an open cut coal mine) in already enriched form, with its subsequent through delivery to the consumer by pipeline on any distances in stream mode, without any intermediate transshipment operations. For this purpose use liquid with set complex physical, sanitary-and-hygienic and ecological properties, simultaneously, in 4 qualities: As environment for grinding material that needed further reduction of size; As separation environment for the subsequent, after reduction of size, deep underground gravitational enrichment of combustible mineral, As motionless filler of the vertical pipeline, for buoyancy in it ready product from mine on terrestrial surface: As carrying medium for final drift of end-product to the consumer by main pipeline. Depending on consumer type of solid fuel, a time of year, and weather conditions in which such, non-polluting, mining-energetic complex functions, there are used various technological approaches as to the general principles of construction of such, non-polluting, beneficiating transport technological process as well as within the limits of separate links of such technological chain, various methods of the regeneration, used many functional liquids which are in the closed contour of circulation between producer of solid fuel and its consumer.
