The authors study numerically a problem on vortex flows in bounded domain in granular material using discrete element method. The granular material is composed of spherical particles with the assigned distribution of radii. Dry friction and rolling resistance at particle interfaces are taken into account. The kinematic patterns of granular material specimen deformation are described, and the trajectories of some particles are shown. The article gives values of normal and shear stresses acting at the study domain boundaries from the side of the material.

The authors use physical and DEM modeling to analyze stresses and strains in broken ore discharged from accumulating bins using an apron feeder. It is substantiated that the determinant of the peak load on the feeder and the discharge unit is dilatancy. It is shown that the absolute value of the peak load is conditioned by physico-mechanical characteristics of discharged ore, structural design of a discharge unit and deformation constraint. The article demonstrates possibility of upgrading one of conventional schemes of discharge unit and shows prospects for new designs.

Variations in strength and stress state of rocks fail to explain the difference observed in efficiency of seismic radiation from separate sources within the limits of the same mine field. The laboratory and numerical experiments show that insignificant variation in ultimate strength of a fracture and, thus, different shear fracture stiffness results in radical change in the seismic event efficiency. The experimentally obtained relations between the key parameters should be taken into account in geomechanical modeling of large-scale objects.

Based on the integrated analysis of micro-strains obtained using white light speckle-photography method in Brazilian Test of rock specimens and analytically calculated elastic fields of stresses and strains, the authors show that there exist significant correlation dependences between the damage in a certain domain of a rock specimen and the level of the external load. Given a verified geomechanical model describing properly evolution of stresses in a rock specimen, this fact offers pre-requisites for estimation of damage in different areas of a rock specimen by monitoring condition only in one of such areas.

The authors have undertaken experimental and theoretical modeling of fracture growth under the penetration of rigid wedge in brittle rock. The test specimens were made of organic glass to facilitate measurement of size and shape of a fracture. The wedge loading was executed quasi-statically on a testing machine and dynamically by a drop wedge. The scheme developed in the framework of the theory of elasticity for the theoretical description of the fracture growth process accounts for the finite size of the wedge cutting point and the influence of free surface. The theoretical and experimental shapes of fractures are compared.

The authors determine basic parameters for elements of axial tunnel fan VO-21(t) with direct annular diffuser. The algorithm is proposed for calculating aerodynamic parameters of the axial fan using ANSYS CFX software, which allows modeling, computation and analysis of effect exerted by various parameters of the fan air section on the fan aerodynamics. It is found that it is possible to reduce the fan impeller metal consumption and inertia moment by redistributing normal inertia force of blades from the boss to the disks. The admissible impeller velocity is related with the thickness of the impeller disks.

The authors substantiate new engineering designs for selective heading machines and cutter–loaders fitted with screw–type cutters. It is proposed to use biconical and conical disc tools and their attachment units to polygonal prisms to equip both bits of heading machines and screw cutters of cutter–loaders to cut structurally heterogeneous rock mass. It is recommended to practice reverse–mode operation of universal radial–type drill bits fitted with disk tools mounted on triangular prisms with a view to widen the front of loading to be imposed on sidewalls. The presented data on modeling stress state of disk tools and variants of their attachments to polygonal prisms show the mechanisms of loading of related parts in the course of rock cutting.

The article presents new test results on structural and chemical properties of mineral formations on the surface of natural hydrophilic diamonds using Raman, X-ray phase and Auger spectroscopy methods. Analysis of morphological features of nano formations involved scanning electron microscope Jeol-5610 and analyzer INCA. Based on the studies into phase composition of diamonds non-recovered in the circuit of kimberlite ore processing, two types of mineral formations are discovered on their surface: micro-formations as silicate nature globules less than 1 µm in size and silicate nano films more than 5 nm thick. The tests detect also presence of layered talc silicates that make diamond surface hydrophilic.

Considering lack of lithium, the authors believe it is advisable to analyze dressability of spodumene concentrates from mine wastes, specifically from tailings of Transbaikal Mining-and-Processing Integrated Works. The analysis includes mineral chemical, and grain-size compositions of raw material, as well as the capacity of spodumene to be separated and recovered. These characteristics make the basis for developing the dressing technology and process flowsheet for the indicated type of technogenic (i.e. resulted from production activities) deposits.

The authors have tested effect of mechanical impact type and energy on selectivity of spodumene ore breakage in a disintegrator and in vibratory and ball mills in terms of pegmatite with lithium content of 0.1%. It is shown that the highest efficiency of mineral dissociation is achieved in disintegration by free impact. Analysis of grain-size distribution and chemical composition and the X-ray study also reveal advantage of the disintegration process, which allows higher content and recovery of lithium in concentrate at reduced sliming.

Under discussion is recoverability of noble and rare metals from caustobioliths (shale, natural bitumen, etc.). The presented mineralogical and technological analyses of samples show higher content of valuable microelements in some of them. All tested samples contain various rank carbon. Depending on the type of the raw material, the research follows one of three lines: stage-wise diagnostic sorption leaching, flotation with pre-milling in amino acetic acid and magnetic concentration. Based on the examination of scattered carbon substance in caustobioliths, it is supposed that concentrations of metals are asphaltene fractions of bitumoids (bitumen-like substance). The research results show prospect of using this nonconventional coal-bearing raw material as a source of noble and rare metals.

To gain the efficient and optimized application of agents MTH and ETH belonging to dithiazinanes to float gold from complex ores the investigation was undertaken on complexing conditions in water environment and at pyrite surface with manually attached gold (FeS2Au) prior to flotation tests. The microscopic and spectral analysis of (FeS2Au) surface after contact with MTH and ETH show the presence of organic S- and N-containing compounds. It is found that selective gold recovery from a gold-bearing material in flotation with MTH and ETH is conditioned by a number of factors that accelerate formation of poorly soluble compounds at the surface of gold particles. The analysis includes the contact time, optimal medium alkalinity, formation of an oxidized film at Au0 particle surface, introduction of modifying agents as additional ligands as well as mechano-chemical acceleration of the complexing. Mechano-chemical treatment with feeding a low soluble agent into a mill before flotation of copper-sulfide gold-bearing ore enabled to higher gold recovery into rough and intermediate flotation concentrates by 15.9 and 4% respectively. In this case Au content in tailings was lowered by 0.15 g/t as compared to flotation experiments with butyl xanthate and its combinations with ETH.
