Abstract. For the pulverisation systems of hydraulic transport complexes used to transport placers from the mining sites to the processing site and using hydraulic monitors to form a hydraulic mixture by washing the placer massif, a methodological support for calculating the parameters and operating modes based on the data of diagrams of relative parameters of the pulverisation process was developed. For the first time, it is proposed to determine the volumes of water and placer supplied to the concentrating production (concentrator), the parameters of the efficiency of the hydraulic transport complex, as well as the characteristics of the pulverisation unit, such as the volume flow rate of water, volume flow rate of placer, volume flow rate, density and concentration of the hydraulic mixture, and the number of hydraulic monitors that provide placer wash-out, by the relative values of the density and flow rate of the hydraulic mixture evaluated by the operational control system. For the first time, formulas for calculating the relative parameters characterising the operation mode of the hydraulic transport complex and the slurry formation unit within the cycle of the process of placer wash-out at the main slurry pumping station are proposed. The existence of the mode of equal distribution of water consumption for slurry formation units that use hydraulic monitors for placer wash-out, in which the total relative water consumption through the nozzles of hydraulic monitors and through the pipelines supplying water to the zumpf is equal, was established. This mode makes it possible to determine the actual values of the specific productivity of hydraulic monitors in terms of solid and specific water consumption based on the diagrams of relative parameters of the slurry formation process. It is shown that the value of the slurry flow homogeneity parameter, which reflects the difference between the actual and the flow rate concentrations of the slurry, is possible to determine by using diagrams of relative parameters of the slurry formation process. For the first time, the dependence of the specific water consumption on the volumetric concentration of the slurry mixture was established, and an approximation of this dependence by an exponential function was recommended. On the example of diagrams of relative parameters of the slurry formation process obtained experimentally in industrial conditions, the adequacy of the proposed calculation dependencies and the possibility of their use for engineering calculations are proved.

Keywords: hydraulic transport, placers, pulp formation, hydraulic monitor, zumpf, determination of parameters.
