FIELD: mining.
SUBSTANCE: invention relates to the mining industry and can be used in the open-pit mining of mineral deposits, for the development of overburden rocks, hydro dumps, tailings, sludge and gold storages. Increasing the concentration of the slurry is carried out in stages, to do this, first with the help of a jetting machine operating on technically pure water, the upper scarp is eroded, then gravity hydraulic transport of slurry is carried out along a pulp ditch in the bottom of the dredger, that is developing the underlying water-cut unconsolidated clay rocks and additionally increases the concentration of pulp, at the same time, the parameters of the processes of hydromonitor and dredger development of rocks, ensuring their balance and stable operation of the equipment, are determined from the system of equations.
EFFECT: improving the efficiency and safety of mining operations in the redevelopment of rock dumps.
