Abstract.Efficiency placer mining technology is largely determined by process of suspended or eroded soil going to the suction pipe, as well as parameters of supercritical regime of the slurry flowing in the suction line. The dependence between the hydraulic transport parameters of the pipe-line and the properties of the transported material was studied. On the basis of known methods, the expressions were derived for calculating the eroding velocity, which described dependence of geo-metric parameters, volume and time of formation of the suction funnel on critical speed of hydro-transportation in the suction line. It is the first assessment of intervals of geometric parameters changes, volume and time of sucking funnel formation at different modes of hydrotransportation.

Keywords: hydraulic transport, the critical speed, suction hopper, underwater alluvium.
