Integrated Environmentally-Oriented Underground Mining and Benefication Technology of Iron Ore

Abstract

There was offered innovative geologic technology of underground mining of ore on deep workings, based on combination of upward method of metalliferous deposit mining and underground benefication. Through the example Estyunin iron-ore deposit (Sverdlovsk Region) there was developed conceptual flow chart of geological technology, including drilling-in by leaded stem and level crosscut (height of lift), preparation and coal mining, ore benefication on underground dressing plant, back fill of exhausted stall by mill tailing, upraise tradable concentrate. There was demonstrated that in spite of increasing of volume of capital mining
operation, offered technology is cost-effective and could provide substantial reduction of negative impact on the environment due to full or partial excluding of placement on the surface of the tailing storages, tailing dumps and other environmentally facilities.
