Modelling Changes in Hydraulic Transport Parameters during Pulp Formation Using Hydromonitors

For the first time, a mathematical model of the technological operation of washing away material that has fallen on the site after a landslide using water jets has been created. It describes the movement of part of the mass that has descended the slope along an inclined channel along a thin layer of highly concentrated hydro mixture formed between it and the bottom of the channel from the liquid supplied by hydromonitors, which acts as a grease with the rheological properties of the Bingham-Schvedov medium. The proposed mathematical model allows calculating the increase in the flow rate and density of the hydro mixture in the second stage of the slurry formation process, taking into account not only the redirection of the water monitor jets, but also the proposed methods for calculating the parameters of the slurry formation process, which can be used to reduce the energy intensity of the transportation process and increase its reliability by preventing dynamic phenomena and emergency stops by determining the acceptable parameters of the mode of destruction of the mound by the jets of the hydromonitor.
