Abstract
A method for open-pit development of non-metallic rock mineral resources includes working out of pit field with horizontal and steep extraction layers with processing of mineral at working site of production ledge. Fractions of end product are supplied to accumulating hopper section storage formed in hole of the ledge of rocks on side non-mining flank lower than the level of cover rocks. Needed fraction is re-loaded to elevating conveyor of pit reloading-and-storage complex, with raising to surface and is reloaded to means of main transport. Overburden is directed for construction of exit roads from the pit and to inner dump.
