Sokolov I.V., Smirnov A.A., Antipin Yu.G., Nikitin I.V., Baranovsky K.V. Efficiency of underground mining of the tarinnakhsky and the gorkitsky iron ore deposits

Abstract

The efficiency of underground mining of the reserves of the Tarinnakhsky and the Gorkitsky deposits being left out of an open pit contour is defined in terms of the analysis of mining-geological and mine technical conditions. An economic-mathematical model shows that the greatest efficiency is provided by the strategy based on parallel construction of mines and simulta-neous putting into operation of the mine fields both in the Tarinnakhsky and the Gorkitsky mines. Sufficiently high profitability of underground ore mining is in its turn pro-vided by application of the advanced low-cost and re-source-saving technology with a mass ore caving and complexes of high-performance self-propelled equipment in all ore mining processes. The schemes of development and ore mining are worked out. Optimal ore extraction parameters are determined. Technical and economic performance of each mine is calculated.

Keywords

Scheme of development, the system of underground mining, block caving, resource-saving technology, economic-mathematical modeling, ore losses and contamination, technical and economic performance.
