FIELD: mining.
SUBSTANCE: method for selective development of upland mineral estate reserves consists in division of a slope into horizons equal to the bench height and tunnel driving along deposit slope. Tunnels are thereby provided with drillhole, blasthole and chamber charges followed by shock blasting, then broken material is taken out and loaded onto the means of transport. On a working platform, formed in this way, mining equipment is placed for selective development of reserves. For this purpose, on the working platform the initial cutting is provided across the strike of mining work front, and the high-priority zones of mineral stock development.
EFFECT: reduction of labour inputs for upland deposit development.
