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.
