The stress-strain state of an elastic plane with elliptical cuts is studied under different loading conditions. The lines of an energy flux are constructed. It is shown that energy transmission into a deformable medium is induced exclusively by external forces applied. The effect of boundary conditions on the energy flux lines is demonstrated.

Based on the analysis of a 2D model composed of rectangular blocks with deformable interlayers, it is found that the earlier model of perfectly rigid blocks is only applicable if interlayers are low rigid and blocks are rigid. Otherwise, the descriptions of dynamic disturbances in such media deviate greatly. The present paper introduces a correction for this restriction, as well as analyzes the elastic properties of blocks and their contribution to the oscillation motion.

The paper describes observations over the gravitation and electromagnetic field variations in a 900 m deep opening in Tashtagol Iron Ore Mine, as well as monitoring of movements in the rock mass and on the earth’s surface. The results provide characterization of the variability of the stress-strain state in the rock mass, and the rock pressure manifestations in the mining area.

Based on the hypothesized material-independent relationship of the normal and shear stresses on the plane of shear, the authors have plotted an envelope of Mohr’s circles, that represents a rock strength condition in the compression stress domain. The relation of the maximal principal stresses extends to the tension domain as a hyperbola, and its parameters can be obtained only in the non-uniform triaxial compression tests. The hyperbolic equation derived provides, in particular, the ultimate tensile strength of rocks.

The paper describes a new estimation method for rock abrasivity as a function of grain size, porosity, rock-forming mineral hardness, structural bond strength and humidity. The cumulative effect of these properties on the rock abrasive ability is represented as a sum of dimensionless indexes in the canonical structural-hierarchical scale.

The paper presents the compression test results for salt rock samples and the study into the stress-strain state of cylindrical samples with different height-diameter ratios. Based on the analysis of a representative structural element of the sample material with a spherical pore, a variant of the fracture mechanism in the salt rock samples under compression is offered, that explains the abnormal response of the limit compression stress value to the geometry of samples in the conditions of dry friction and sliding due to lubrication.

The paper describes a mathematical model of a 3D back-action hydropercussion system of self-excited oscillation type. The author determines the space of dynamic similarity criteria and numerically investigates the output characteristics of the mentioned system. By the analytical results shown as nomograms of isolines plotted for the integral characteristics and based on the theoretical oscillograms and phase curves of the dynamic characteristics, the behavioral features of the system in the space of the main similarity criteria have been revealed.

The characteristics and development prospects of backfilling in deep mines are discussed. The authors propose a new engineering solution for the long-distance pipeline transport of the high density consolidating backfills by using hydrodynamic pressure activators. This technology allows a longer transportation distance, up to 3.5 km. The pilot-full-scale test procedure for the technology is developed and proved on a test ground in Oktyabrsky Mine, Transpolar Branch of «GMK Norilsk Nickel» Joint-Stock Co.

The paper presents the calculation of pressure losses in blade rows of an impeller and directing vanes for a number of axial tunnel fans. The found rationality domains of the design parameters for fans with impeller diameters 1600, 1800, 2100, 2400 mm will allow assessment of a fan installation efficiency as early as at the design stage. Also, the author has validated the choice of an aerodynamic configuration and design parameters for the components of a fan, and calculated geometry of the fan impeller blades for subway station-to-station block ventilation.

The article presents the analysis of application of a natural and then modified mineral sorbent to strontium removal from natural and waste waters. The authors have shown the high-efficient sorption capacity of naturally occurring and thermally treated brucite relative to strontium. Besides, they have revealed the relationships of the mineral sorption and pH of a water medium, as well as the interaction of strontium and the sorbent surface.

Based on the physico-technical operations involved in the mineral processing technologies, the optimal production conditions are found for refractory fiber materials, aluminium, silicium, their compounds and other valued components. Ecologically safe and efficient aggregate technologies are developed for recovery of valued components from nonmetallic minerals and anthracides (brown coals).
