Abstract
Volume shares taken by every phase of the heterogeneous mixture for coal particles in the shape of cubes, plates, needles, bricks and pyramids allow defining true density of mark D bank coal. Using the fineness all-up, taking into account the ash content and the forms of the extruded coal particles, we obtained the volume for heterogeneous water-coal suspension 16 % less than the cubic grains volume, calculated by the old method.
