Analysis of the domestic iron ore pits showed that with the increase of their contours complication of conditions of mining operations in the production of deep horizons of the periodic flooding of storm water and groundwater are observed in the last decade. The existing technological schemes of benches development with the use of direct mechanical shovels only are not safe and effective in these conditions. Urgent scientific direction is the development and determination of new resource-saving and safe technological schemes, that are adapted to the complex hydro geological conditions of deep horizons of iron ore pits. Combined technological diagrams of development of deep horizon of iron ore pits under difficult hydro geological conditions are developed and classified; their technical and economic indices are determined in the paper. The dependence of pit deepening rate on organization of works on development by combined complex cross-loading equipment in the hydrogeological conditions of the range typical for the ferruginous horizons Krivbass is established. |
