FORMATION, EXISTENCE AND BREAKUP OF FLOCCULATION STRUCTURES
THIS WORK PRESENTS THE RESULTS OF INVESTIGATION OF THE STRUCTURES FORMED BY FLOCCULATION OF FINE COAL PREPARATION PRODUCTS SUSPENSIONS.
Consideration of flocculation structures formation was carried out on the base of the extended DLVO theory with taking into account the amount of polymer macromolecules on one particle of known diameter. It was shown that the particles of the solid phase with diameter more than 1 μm are flocculated by ortokinetic way for a few seconds and submicron particles are flocculated on perikinetic way for 400–600 seconds. On the base of the theory of fluids flow in capillary-porous media it has been developed and experimentally validated a model describing the kinetics of flocs mechanical syneresis. It was shown the possibility of reducing of the water content of coal froth flotation concentrate cake by mechanical syneresis and, accordingly, cost decrease of concentrate thermal drying. Theoretical analysis of flocculation structures strength for maximum shear strain state, allowed to calculate the maximum shear yield stress depending on the diameter of the particles and the flocculant dosage. Rheological study on coal froth flotation concentrate showed that the nature of these suspensions without flocculants are close to Newtonian plastically fluids, and using flocculants are pseudoplastic properties. Experimentally obtained values of shear yield stress for coal froth flotation concentrate not contrary with theoretically calculated one. Also the approach for evaluating the effectiveness of suspensions flocculation conditioning based on experimental determination of filtration and structural-mechanical properties of filter cakes was proposed. The obtained results allow to predict the performance and speed of the belts. To perform the necessary calculations in this work was the interrelation between hydrostatic pressure and drainage time was established.

INCREASE OF THE RELIABILITY OF THE DESIGN OF STEEPLY ANGLE ELEVATING BELT-WHEELED CONVEYOR FOR HANDLING BULK LUMPY MINING LOADS
In the previous construction of the steeply inclined belt-car conveyor clamping of the layer of load by side belt sections was performed directly by the pressing levers. In that case the contact between levers and belt occurs in one or two points because of indeterminate surface of the load layer. It’s difficult to keep the overlapping connection of the belt side sections especially under atmospheric precipitations, when the coefficient of friction between levers and belt is decreasing. In the suggested construction clamping of the load layer is performed by straps connected to the ends of levers and regulators with spiral springs attached to the moving supports. The principle of action of the straps with regulators is similar to the automobile safety belts. The conveyor has the high level of construction continuity and sufficiently increase the reliability due to the exclusion of accidents caused by falling out of lumps of load.

STRESS STATE MONITORING OF ROCK MASS USING ACOUSTIC EMISSION EFFECTS IN ANISOTROPIC COMOSITE MATERIALS
Possibility of using acoustic emission memory effect in anisotropic composite materials for evaluation of stress-strain state of rock mass is shown. The analysis of laboratory research results of common and specially synthesized materials is performed. It was found that the angle between direction of uniaxial compression application and direction of lamination (elastic inclusion plane for synthesized material) in composites has a significant impact on the behavior of acoustic emission during the first loading cycle, and manifestation of acoustic emission memory effect. Thus the lowest values of the acoustic emission activity are when such angle is 90° in the first loading cycle. When studying memory effect it is manifested most clearly at an angle of 0° for synthetic materials with elastic inclusion and 45° for layered composites. A method that allows continuous monitoring of maximum principal stress orientation acting in the area of excavation is offered.

POLARISATION-ACOUSTIC METHOD OF DEFINITION OF THE RESIDUAL AND ACTING STRESSES OF ROCKS
The law of change of a relative rate of speed of passage of the ultrasonic polarized shift wave from change of mechanical stress in firm materials is installed. The law consists that change of mechanical stress in firm materials, including in rocks, leads proportional, depending on magnitude of the installed new characteristic of a firm material – the wave module of stress – K, to change of a relative rate of speed of passage of an ultrasonic shift polarized wave in a direction perpendicular to a direction of act of stress. Change of a relative rate of speed of passage of the ultrasonic polarized shift wave, with the vector of polarization coinciding with a direction of stress, is caused by that stress excursion in a direction perpendicular to a direction of passage of an ultrasonic shift polarized wave calls material deformation. The formulas are gained, allowing to define a sign and magnitude acting and residual stresses in firm materials in certain directions for certain baseline of measurement (Law of Kushbakali). On the basis of the installed Law of change of a relative rate of speed of passage of the ultrasonic polarised shift wave from change of mechanical stress the method of definition of the residual and acting stresses in rocks is developed.

PROBLEM OF PARETO OPTIMIZATION OF A TRAJECTORY ON A NETWORK AS A METAMODEL OF MULTIOBJECTIVE CHOICE OF PROJECT PARAMETERS FOR MINING ENTERPRISES
The paper treats the problem of formalization of the decision-making model for selecting project options for development of solid minerals deposits. Multi-criteria nature of the decision stems from the need to balance the interests of a company – the subsoil users (represented by the integral economic effect of the project) and the state – the subsoil owner (expressed by the budget income and completeness of extraction of balance reserves of solid minerals from the subsoil). The developed approach is based on common features of the mining industry and its design, consisting in the binding of the majority of design decisions to the time and at the same time to the space, the specific character of the dynamics of the production process, including the dynamics of mining and providing works and equipment assignment to sites, the irreversibility of the changes of the entire natural-technological system state. To represent the relationships between qualitatively different alternatives of design decisions (including mining system, technological zoning of mine field and the opening scheme), the form of the tree of alternatives is proposed, end vertices whereof corresponding to fully defined project alternatives. To represent the implementation of alternatives in time and space the form of contourless oriented graph of states and transitions (GST) is introduced. The ways to represent mining operations dynamics, equipment fleet composition and its assignment to the areas of mining and providing jobs in the form of GST are proposed. The choice of the project variant is represented in the form of the problem of multi-objective optimization trajectory on GST. It is substantiated that the problem of Pareto-optimization of trajectories may be reduced to the problem of finding the entire set of suboptimal trajectories on GST which may be solved either by modified Dijkstra’s method or the branch and bound method.

This fact causes considerable bias (systematic inaccuracy) of estimates obtained using the conventional least square method. In terms of the linear and parabolic approximating regressional relationships, the analytical expressions are derived for quantitative estimation of bias of values obtained by the conventional least square method for the parameters of the regressional relationships as functions of allowable random error in measurement of input variable (input signal).

Mathematical modeling allows designer to define all the necessary parameters of freezing: freeze time; consumption of solid carbon dioxide; total amount of carbon dioxide;, the shape of icewall with possible influence of heat sources (heating system, pipes, etc.). Thus, the presented method opens up opportunities for designers to expand the practice of introducing new solid carbon dioxide freezing methods.
Key words: artificial ground freezing; solid carbon dioxide; dry ice; ground improvement; mathematical modeling.

ANALYSIS OF DYNAMICS OF FLOODING IN MINE CONSERVATION IN KUZBASS
There are two main methods of mine conservation in Kuzbass. The first of them is a completely flooding to spouting point, which is called «wet method». The second way of conservation («combined method») is a supporting the groundwater level at a certain point, which is determined by the conditions of exception flows to adjacent operating mines as a rule. The 15 flooding mines of Kuzbass are reviewed. There are regular measurements of groundwater level from the beginning of their liquidation in these mines. The periods of the active process of flooding (from the beginning to the moment when the level of the floodwaters rosed the surface aquifers and the process of flooding took protracted, or to special mark point when pumping-out started in the flooded mine) are analyzed. The results of the analysis reveals that the conservations of the mines in Kuzbass by «wet» and «combined» methods are specified by large fluctuations in the velocity of flooding, the analysis of variance of which can be produced by using methods of the theory of random functions. The groups of flooding mines are defined by speed’s characters of flooding. The method and the results of the analysis of variance of the speeds of flooding are given. The regularity of the speed of the flooding new mines is revealed by analysis of all performed measurements. This regularity has exponential character with defined parameters and can be used for flooding predictions.
Key words: mine, conservation, the speed of flooding, the dynamics of the flooding process, correlation function, analysis.

WAYS REDUCE THE ENVIRONMENTAL IMPACT ENVIRONMENTAL COAL PLANTS RUSSIA
The data given show that Russian coal plants are a source of trace elements and radionuclides contamination of the environment. This is due to the concentration of trace elements and radionuclides in ash and slag dumps TPP and in air emissions of fly ash thermal power plants.
To reduce the effects of trace elements and radionuclides needs a well-organized control, as the content of trace elements and radionuclides in coal and in ash waste and emissions of fly ash thermal power plants.
Significantly reduce the environmental impact of coal-fired plants on the environment is possible only with the introduction of innovative clean technologies in the electricity and coal processing. The Energy Strategy of Russia for the period up to 2030 is planned to increase the introduction of new environmentally friendly and highly efficient coal combustion technologies. This should dramatically decrease the environmental impact on the environment coal-fired plants in Russia.
Key words: coal, trace elements and radionuclides in coal, fly ash thermal power plants, emissions from thermal power plants, the impact on the environment and human health harmful impurities coal plants.

STUDY OF THE STRESS STATE INFLUENCE ON INDUCED PIPELINES MAGNETIC FIELD
The paper studies the correlation of the steel pipe mechanical stresses with its magnetic field parameters. Stress states in the pipe metal can lead to the serious accidents, but they are difficult diagnosed at the predestruction stage. This question was studied by different authors, in particular Aginey R.V. [1] Kuleev V.G. [5, 6], Lopatin V.V. [5]. During the experiment on Mining University basis, and the calculation in the software package ANSYS MAGNETOSTATIC 15.0 authors obtained three mutually orthogonal components of the magnetic induction distribution graphs of unloaded and loaded horizontal or slightly inclined steel pipe placed in a magnetic field of the Earth. The data are in good qualitative correlation with the calculated distribution of the stray fields of the magnetization, previously obtained by other authors [5]. It was found that the dependence of the field strength are complex and increasing load leads increasing of the extrema absolute values. The results can be used to magnetograms interpretation obtained by diagnostic examination of pipelines, determining stress states in the metal pipe, and good agreement of the magnetic induction experimental and calculated values enables the use of ANSYS MAGNETOSTATIC to calculate the magnetic field distribution under loading in more complex cases, than considered in this article.
Key words: stress stage, pipeline, coercive force, magnetic induction, diagnostic, pipeline, ANSYS.

METHODOLOGICAL BASIS FOR THE ORGANIZATION OF INNOVATIVE SOLUTIONS FOR THE PROTECTION OF THE ATMOSPHERIC AIR IN THE UNDERGROUND TECHNOSPHERE CITY
The development of large cities, accompanied by serial deterioration in ambient air has determined the need to develop effective measures for the protection of the technosphere environment based on advanced achievements of scientific-technical progress.
However, in contrast to well-established public opinion, modern scientific data show that in closed spaces surface and underground infrastructure of the city air pollution can be dozens of times higher than outside. In the early 1950-ies found that allergies and other chronic diseases linked to air pollution indoors.
Today, people living in cities of developed countries in the world spend most of their lives indoors. Therefore, the increase in time of exposure to air pollutants causes an increase in the number and severity of allergic reactions.
In the result of the research conducted in the air atmosphere of the Moscow residential and public buildings found about a hundred of inorganic and organic chemical compounds belonging to different classes of risk. Among the volatile chemical compounds found in the air more often than others, the most toxic formaldehyde, phenol, benzene, styrene, ethylbenzene, toluene, xylene, aldehydes, acetone, ammonia, ethyl acetate, oxides of nitrogen, oxides of carbon. In addition, in the air of buildings contains aerosols of heavy metals: lead, cadmium, mercury, zinc, Nickel, magnesium, chromium and other
The article presents the results of the development of the fundamental principles of the organization of activities for the protection of the atmosphere underground technosphere cities. Typed the impacts of pollution technosphere atmosphere on the results of the various economic activities in the underground space of the metropolis.
