Abstract
Having accounted coal particles after fragmentation on different equipment, particles in the form of needles, cubes, plates, blocks and pyramids were distinguished. After the analysis of the research to define the speed hindered falling of particles of different forms in water (hydraulic fineness) there have been proposed dependencies considering the density of the heterogeneous carrier phase, effective viscosity of water containing coal mud in different quantity, equivalent diameter for different forms of coal particles and the seeming density of dry coal at a specific ash content and average humidity.
