METHOD OF RE-LAYING OF ROCKS OF HYDRAULIC DUMPS WITH HYDRAULIC MONITOR AND SUCTION DREDGER Russian patent published in 2019 - IPC E21C41/26 

FIELD: mining.

SUBSTANCE: invention relates to the mining industry and can be used in the open development of mineral deposits. In method of re-laying of rocks of hydraulic dumps with hydraulic monitor and suction dredger, parameters of processes of water jet and dredging of rocks are first calculated using system of equations. Then, based on the performed calculation of parameters of jetting and dredging of rocks, dredge is selected, which is used to develop unconsolidated clay rocks of hydraulic dump, and hydraulic monitor, which is installed on upper ledge consisting of consolidated rocks, technically clean water is supplied to hydraulic monitor and washed out of consolidated rocks, thereafter, the hydraulic mixture is directed by gravity flow to the bottom of the dredge, which develops the rock and additionally increases the pulp concentration moved along the pressure pulp line to the new place of laying.

EFFECT: improving the efficiency and safety of mining operations in the redevelopment of rock dumps.
