Development of environmentally safe methods for consolidation of dusting surfaces of the tailing dumps
The authors propose a method for consolidation of dusting surfaces of the tailing dumps. The most effective way to achieve this purpose is the integrated use of coagulant and flocculent reagents. The data analysis shows that samples treated with composite lime and PAA-GS polyacrylamide solutions have the highest mechanical strength.

An alternative technology of ore excavation in contact with the filling mass
The authors propose a new resource-saving technology for extraction of ore deposited in contact with the filling mass. This technology enables better extraction of the mineral, reduces ore dilution with the backfilling material, improves profitability of the mineral resource industry, while ensuring safe working conditions. The authors recognize as the most effective one the scheme of ore extraction in contact with the filling mass by means of forming ductile filling masses with a strengthened layer along its contact with the mineral.

Geomechanical measurement of overlying rock hydrogeological conditions change during hydraulic borehole mining of iron ore
The authors explore the connection between hydraulic borehole mining of iron ore in Kursk magnetic anomaly with solution of a number of geomechanical and hydrogeological problems. They provide the calculation of the stress and strain state of solid ore and superincumbent rock under different values of extracted ore volume and water pressure

Forecasting enrichment figures at the processing plant «Pechenganickel» using UniFlot software package
The authors provide the results of testing and forecasting the performance indicators obtained using UniFlot software package. They consider the behavior of each discrete floating fraction from the selected flotation composition. They also compare the forecasting and production data in order to assess the flotometry accuracy. Based on the calculation results, the ways to improve the enrichment process are identified.
