Abstract
It has been found to be economically expedient to develop the west wing reserves of Oktyabrsky Mine by cut-and-fill method with cemented backfill of primary stopes and dirt fill of secondary stopes. This method shows better performance in terms of ore loss and dilution as compared with the current mining system at the same quality of ore produced. Feasibility study of the two variants of process design in the full cycle of mining, processing and recovery of primary metal (nickel) and associated metals (copper, platinum, etc.) shows that the proposed mining system allows higher profit per unit of ore mining and processing.
