FIELD: mining.SUBSTANCE: proposed method involves open, underground or combined development of ore deposits, which is performed in an automated mode with extraction from ores of massif of crude high-melting metals using a melting method and a plasmotron in two stages, immediately from excavation elements of quality ore, with further separate excavation of temporary non-quality, non-quality and poor ore and rock.EFFECT: improving development efficiency of deposits of polymineral metal high-melting ores, which consists in compact and continuous metal production, improvement of complete use of resources and produced mineral raw material, labour productivity, economy and ecological properties of production, obtainment of finished product immediately during development of ore massif, reduction of capital and operating costs, and in creation of conditions for arrangement of automated mining and smelting production. |
