Purpose - to study the effect of polarity of a dispersion medium, mineralogical composition and particle size of coal, the nature and concentration of dispersants and stabilizers on the sedimentation and aggregate stability, reologichesoe behavior and electrokinetic properties of composite coal-water systems. Research methods - rheology, electrokinetic. Theoretical and practical results of the study carried out for the first time, sedimentation stability of the diluted and concentrated suspensions of coal various stages of metamorphism in an environment of lower aliphatic alcohols of methanol - pentanol. It is found that the highly concentrated coal-water slurry have somewhat less strength and toughness values ??than we investigated coal slurry obtained using fusels The effectiveness of implementation, results introduced for energy complex of Ukraine, which received two acts testing. Application-energy generating installations CHP boilers as a substitute for fuel oil.
