Abstract. properties of coal-water slurries were studied in two separate phases: a rheological phase and a pipeline phase. the primary purpose was to investigate the rheology of fine coal slurries, and the secondary purpose was to determine whether the energy requirements of a coal-water slurry pipeline could be predicted from the rheology.
