A process for producing a coal-water slurry having a high coal concentration, a low viscosity and a good stability is provided, which process comprises causing the slurry to have a composition of coal particles so that when the particles are divided into 8 fractions, each having a particle size range listed below, then the proportions by weight of the particles contained in the respective fractions, relative to the total weight of the particles contained in the slurry can fall within the following numeral value ranges: -F1: (DL/4 to DL) 29.0 to 50.0% by weight -F2: (DL/42 to less than DL/4) 20.0 to 25.0% by weight -F3: (DL/43 to less than DL/42) 12.0 to 15.0% by weight -F4: (DL/44 to less than DL/43) 6.0 to 10.0% by weight -F5: (DL/45 to less than DL/44) 3.0 to 12.0% by weight -F6: (DL/46 to less than DL/45) 1.5 to 5.2% by weight -F7: (DL/47 to less than DL/46) 0.8 to 4.0% by weight -F8: (DL/47 to 0) 0.7 to 9.0% by weight - wherein DL represents the maximum particle size. |
