FIELD: mining.
SUBSTANCE: in method for development of solid minerals deposits, non-uniformly scaled and various-quality extraction elements within the borders of deposit and its developed formations are extracted on the basis of deep differential zoning based on wide complex of minerals and rocks quality indices. Breaking of hard rocks and strong semi-hard rocks is carried out by blasting of pinpoint borehole charges of small and low diametre, and breaking of tight and weak semi-hard rocks is done by mechanical ripping. Deeply selective dispatch of various-quality mineral mass, surrounding and surrounded rocks is carried out. End-to-end organisation-technological mineral preparation is carried out in head-mineral-preparation aggregate.
EFFECT: invention makes it possible to improve efficiency of deposits development, to produce various mineral intermediate products and finished mineral products in a single technological cycle.
