Abstract
In this paper the results theoretical estimation of value yield shear stress at the hydraulic transportation of poly-metallic ore tailings are presented. In basis of a method separate positions of the similarity theory are used thus in consideration the combination of numbers of Reynolds, Froud and Euler which set have led to the new dimensionless criterion describing the yield shear stress is accepted.
