And dependence of this ratio from the flow height differs with different sizes of the par-ticles. The paper demonstrates that, for cer-tain categories of the sizes, this ratio can possess another sign with increased depth of the flow forming a barrier for procedure of the particles weighting. Methods and algo-rithm of calculation has been designed for critical speed of hydrotransporting and maximal height of the particles migration for the poly-disperse materials with different fractures.
