The article focuses on seismic monitoring of causes of landslides. Such studies are of great importance in open pit mining in permafrost rocks. Extensive mining-induced impact in combination with natural thawing of permafrost as a consequence of the planet warming may end in catastrophe. The authors describe a procedure for plotting velocity profiles of seismic waves along slopes in the presence of extremely contrast discontinuities conditioned by permafrost rocks. The presented approach enables studying slip surfaces of landslides and detecting potential failure zones where wave velocities are lower due to extensive jointing. The processed field data obtained in the area near Chagan-Uzun settlement in Kosh-Agach district of the Republic of Altai are reported.

The article describes a proved method to calculate stress state of support and surrounding rock mass, considering roof and wall rocks displacement until the contact with the support. The method is based on the use of the intact rock mass stiffness matrix formed prior to mining. Modeling of drivage using the method of initial stresses allows splitting the problem into two subproblems: the first subproblem is on mechanical state of rock mass during roof and wall rocks displacement, the second subproblem describes joint deformation of roof rock, walls rocks and support. The cases of stress calculation for rocks and support, considering support installation conditions, are described. The stress behavior depending on the value of roof and wall rocks displacement until the contact with the support is determined. The features of the method application in case of greatly different mechanical characteristics of rocks and support are discussed.

Actual physical models and discrete element method are used to analyze stress-strain state of broken rocks at the moment when an apron feeder starts discharge from floor storage. It is shown that conventional designs of discharge units of floor storages fail to eliminate broken rock dilatancy which is a determinant of the peak load on the feeder at the moment of its actuation. Based on the investigation results, the authors propose an approach to filling floor storages with broken rock and a structural layout for the storage discharge unit. The offered engineering solutions enable preventing from dilatancy-induced impact on stress state of broken rock being processed and, as a result, elimination of peak loads on feeders.

Based on the tests of packings of calibrated glass balls with a diameter of 1 mm, it is shown that multiple point impacts improve waveguide characteristics of the mediumconducting paths composed of force chains emerge in the test material. The further quasi-static alternating shears change the packing of particles, break the chains and reduce conduction. If continued onward, the multiple impulsive loading results in recovery of the chains and in better conduction of the paths.

Experiments allowed finding regular patterns in propagation of elastic P-waves in specimens of black coal exposed to uniaxial compression and triaxial compression by von Karman. It is shown that in case of uniaxial compression, the largest information content is ensured by translucence in perpendicular to bedding and loading axis of coal specimens. Such translucence exhibits four stages of deformation of a specimen. The information content of translucence under triaxial compression reduces with the increase in the constrained pressure that prevents from disintegration of a coal specimen. Four deformation stages are best identified with the constrained pressure of 2.5 MPa, while only stages of specimen consolidation and failure are traced at the pressure of 10 MPa.

The author reports test data on disc-shaped specimens of rocks and model media with a hole drilled through the center of the specimens loaded along the diameter. The test data processing uses non-local fracture criteria. The calculated destructive forces are compared with the measured destructive loads. Based on the tests of specimens with the central through holes, the tensile strength algorithm is presented.

Gravity-induced horizontal stress in rocks is assessed in the framework of physical simulation using a flexible thin-walled cylinder. Compression of loose geo-materials changes diameter of the cylinder, which allows estimating horizontal stress. The observed dependences with various compacted geo-materials are then theoretically approximated based on characteristics of porosity, rock deformation modulus and Poissons ratio. The obtained relations are applicable to estimation of gravity-induced horizontal stress in an intact rock mass.

Horizontal stress, gravity, consolidating rocks, porosity, deformation modulus, Poissons ratio

Based on the developed procedure, experimental regularities are obtained for the formation of submicron particles under rock failure. The experiments involved explosion load on rock specimens and their uniaxial compression with the concurrent control over size and amount of particles until failure using laser spectrometry. It is found that most of all particles are formed in the size grade of a few microns irrespective of the kind of loading. Dynamics of the formation of particles depends on structural characteristics of specimens and on the value of the compression stress. The authors emphasize the promising nature of the experimental results usable both in the environmental monitoring and for disaster prediction in the course of mining.

The article reports data on continuous indentation of different rank black coal and anthracite. The test specimens are specially prepared, and their faces are differently oriented relative to their bedding planes. Different mechanical behavior of coal and anthracite microcomponents in different planes relative to bedding is identified, and relevant values of elasticity modulus and hardness are determined. The measurements exhibit spatial anisotropy of microlevel mechanical properties of vitrinite and inertinite.

The article presents the remote monitoring systems for operation of high-voltage substations and shovels, designed at the Karaganda State Technical University and introduced at Shubarkol-Komir open pit coal mine. The systems measure power consumption parameters and controls power consumers and electrical protection. The high-voltage substation monitoring systems transmit data via rf modem, the shovel operation monitoring systems use GPRS modems to transmit data via Internet to a central operator office. In the course of trial operation of the remote monitoring systems, it was succeeded to save power owing to elimination of idle operation of heavy-duty mining machines; moreover, the scope of the continuous control covered power consumption and electric protection at substations and on shovels.

Under discussion is the particle and bubble interaction in froth flotation. Water flow from an interlayer between a particle and a gas bubble under effect of hydrophobic component of wedging pressure is studied. It is assumed for a mineral to be extracted, that electrostatic interaction slightly influences the particle and bubble contingence and the liquid interlayer thinning. For this reason, particular attention is given to the effect exerted by mineral particle surface hydrophobicity on water flow rate from the interlayer. It is found that water flow rate under influence of hydrophobic component of wedging pressure is less than water flow rate under physical adsorption of a reagent. The authors hypothesize that hydrophobization creates areas on the mineral particle surface, where the reagent species active relative to gaswater interface attach in accordance with the polarity equalizing rule. Physically adsorbed reagent species pull out water from the interlayer after the interlayer rupture and, thus, remove the kinetic constraint of the particlebubble attachment.

Laser diffraction analysis and dynamic light scattering method are used to study highly dispersed particles generated during milling of leadzinc ore (Gorevsky deposit), rich sulfide and impregnated coppernickel ore (Norilsk and Kingash deposits), as well as Gorevsky Pb concentrate and Sorsky deposit Cu and Mo concentrates. Zeta-potentials of particles are measured in clarified (colloid) solution above precipitation; surface composition of ores and their fine sizes is analyzed using X-ray photoelectron spectroscopy. The highest yield of particles under 5 ?m size grade (to 3 total percent) was observed in case of Kingash ore; moreover, zeta-potential of these particles was positive at pH 9.5 and surface compositions of precipitation and colloid particles were nearly the same. Comparatively high content of ultra dispersed fractions was observed in case of Gorevsky ore and Pb concentrate. Clarified solutions contained mostly aggregates of nano-size particles, first of all, Si and Mg minerals, with the hydrodynamic diameter of 5001200 nm, which shows little changes with time. Sulfide component of hydrosols contains many nano-size particles of minerals that better resist oxidation (sphalerite, molybdenite, pentlandite, chalcopyrite) and, in particular, can transfer metals within the ambient medium.

The article illustrates feasibility to predict changes in energy content and reactivity of scheelite concentrate after mechanical activation based on X-ray diffraction analysis data under onward low-temperature (under 100?) sodium leaching. The complex nature of changes in the energy content and reactivity of mechanically activated scheelite under influence of structural changes in mineral particles is determined. It is confirmed that energy accumulated in the form of surface energy and micro-deformations during mechanical activation affects further leaching performance. The procedure and criteria developed to estimate efficiency of mechanical activation of scheelite make a technical background for energy-saving technology of scheelite concentrate treatment directly at mining and processing plants.

Integrated development of Volkov copperironvanadium deposit is impossible without heap leaching of copper from old oxidized and complex ore stock pile. The current condition of the stock pile imposes risks of pollution on the Laya River water and on the topmost aquifer groundwater. The natural protection barrier between the groundwater and the old oxidized and mixed ore stock pile is rather good. Permeability of the upper layer of the stock pile, determined by the standard procedure in accordance with the construction norms and regulations, is classified with ambiguousness. For final decision-making after geological engineering survey, permeability characteristics of the upper layer were analyzed using different?concentration sulfuric acid solutions to simulate heap leaching conditions.
