METHOD FOR RECLAMATION OF AN ELLIPSOID ROCK DUMP WITH AN ENVIRONMENTALLY FRIENDLY ORIENTATION Russian patent published in 2024 - IPC E21C41/32 A01B79/02 

FIELD: mining.

SUBSTANCE: method of recultivation of rock ellipsoid shape of dump relates to mining, in particular, to development of deposits by open method and restoration of territories disturbed by mining operations. Method includes preparation of the lower base of the dump body along the terrain, laying of wastes into the dump, formation of external slopes of tiers of an ellipsoid dump with reclamation along the perimeter by sub-tiers of 5-7 m and with slope angles in range of 18-22° with the slope of the sites towards the dump body, their coverage with a fertile soil layer (FSL), followed by sowing herbs and planting seedlings. Preparation of the lower base of the body of the dump on the terrain is made by removing the FSL with a bulldozer for optimal entry along the dump boundary and its laying into the permanent storage along the perimeter next to the designed ellipsoid dump, having retreated the strip for the accumulation of potentially fertile rocks (PFR), and removal of PFR by excavator dragline for optimal entry along the dump boundary and its laying into the permanent storage warehouse along the perimeter next to the designed ellipsoid dump in the left strip. Within the framework of mining technical reclamation of external slopes of tiers with an excavator dragline installed near the warehouse along the perimeter, the PFR is applied to the higher external slope with subsequent transfer of the PFR to the pile on the higher platform of the sub-tier. At the site, the same excavator forms the PFR and similarly vertical movement of PFR is continued from bottom to top, applying a layer of PFR. Similarly, a soil layer is applied on a higher external slope with subsequent transfer of FSL into a pile on a higher platform of the sub-tier. On the site, the same excavator forms a soil layer and similarly continues the vertical movement of the FSL from the bottom upwards, applying the soil layer.

EFFECT: improving ecological efficiency of recultivated rock dump.
