The article explores the issues of modern higher education in relation to the state transition to the knowledge-based economy. Considering the issues within the socio-philosophical aspect results in understanding a phenomenon that prolonged «ob- solescence»of knowledge, separation of theory from practice overextend the measure of sustainability of an educational organization and methodically generate the necessity to modernize its basic processes: education, science and innovations. The research educes the differences between the operational management, focused on performing quantitative indexes, and strategic management, targeted to qualitative changes of the basic processes. The article investigates the processes of forming development strategies and strategic projects of universities. It reveals that strategic projects, focused on strategic management, can provide major breakthroughs of the universities unlike the development programme, realized within the operational management of a university. The article demonstrates the activity results in forming a development programme and experience in realizing strategic projects by Federal State Budget Educational Establishment of Higher Education «Reshetnev Siberian State University of Science and Technology» example.

The article aims to establish the causes of dissatisfaction with higher education reforms. The author sees their origins in the discrepancy between the conceptual metaphors of education, which guide faculty and mega-and macro-regulators of the educational system in their decision-making process. The commercial logic of the latter forces individuals and organizations of higher education to focus on competition. However, this is in odds with the Russian mentality, and competition is often carried out through cooperation. Confronting the paternalistic management style is a powerful integrating factor. The author identifies and describes several levels at which competition and cooperation relations can be traced, and also characterizes socially approved and deviant ways to implement them. Relations of cooperation are mechanisms of integration in the subsystem of higher education, and mechanisms of differentiation are realized in competitive relations. Both mechanisms are interrelated and interdependent, and express the processes inherent in the development of any system. However, the methods by which integration and differentiation are implemented will affect the viability of the system and the moral climate within it. In the light of citizens» dissatisfaction with the ongoing reforms of higher education, their axiological aspect is extremely important. It is concluded that it is necessary to return to the ideals of dignity, as well as scientific, teaching and student ethics at higher school, which is possible only if the mega- and macro-regulators adhere to the principles of managerial dialectics; balancing the vertical of power with horizontal network relations based on competition and cooperation mechanisms within the professional community. In this situation, the professional community itself will be able to identify and propose indicators relevant to higher education as a process, result, and value, methods of assessment for the educational and scientific activities of universities and the efficiency of the faculty.

The paper analyzes processes and results of the commercialization and commodification of education seen as leading trends in Russian and world education. Methodology and research methods. Theoretical analysis of the problems appeared in Russian and world education was carried out in the context of socio-psychological and practical psychological analysis of its trends. The world and all spheres of its existence and development, as one of the manifestations of the phenomenon of globalization, taking place in the context of a systemic crisis of capitalist relations, is experiencing an intensive growth of the processes of commercialization and commodification. These processes are the most significant where commercialization, contrary to the traditions and basic meanings of this or that practice, seems to be a natural part of activities. One of these areas is education. Modern primary, secondary and higher education in the countries of the former USSR and many other former countries of the «socialist camp» are experiencing an intense crisis. They are increasingly desacralized whereas, their conceptual basis is almost completely lost. It becomes not an institution (of retransmission and creativity) of culture and human development, not an institute of care for the younger generation, but an institution for the sale of services for the (trans) formation of a «serviceperson». Commercialization in the conditions of desacralization goes into total commodification. Education becomes the business of delivering «educational services.»The state bureaucracy, as well as heads of corporations and enterprises of various types actively and systematically intervene in the processes of education. Their goal is to impose education, starting from the very first stages and ending with the last ones, their schemes, values, formats. These goals of consumption and exploitation of human and other resources are alien to education as early as possible. As a result, the selection and upbringing and training of professional, corresponding to a certain organizational culture of personnel goes into the formation of specialists with a narrowly limited, special set of knowledge, allowing to perform certain production and everyday functions, but not allowing a person to self-realize, form and develop themselves as an individual. Large-scale and aggressive penetration of alien ideas and structures of relations, the seizure of education by ideology and technologies of the «mar- ket»type leads to the phenomenon of «death of the university», other levels of education. The systemic crisis of education, deformations in the relationship of a person with himself and the world is the result of desacralization, the identity of ignorance and alienation. However, universities and schools, as specific for each time space of the dialogue of generations, the creative dialogue of man and culture, continue to evolve. Their forms change and are refined, in a battle with consumerism and commodification, their priorities and functions. They continue to exist not as functions of governing the state by «faceless masses». They continue to exist not as a function of the exploitation of human resources by business, but as a function of cultural transmission and development. Commercialization can be a situational and insignificant component of the successful work of universities and schools, but not the goal and not the main condition for their livelihoods.

The article highlights the problems and the main directions of interaction between professional educational institutions (UPE) and entities of labor market as a necessary condition for improving the quality of training of the staff. The author analyzes the nature, structure and functions of the modern labor market, its requirements to the quality of students» training at educational institutions (UPO), technology of labor market regulation and employment sphere. The article shows the main directions of social partnership in the issues of interaction of UPR with the subjects of the labor market. Specific recommendations on the implementation of the main areas of interaction of vocational education institutions with the subjects of the labor market are highlighted. The author makes conclusion that for successful interaction of the UPR with the subjects of the labor market it is necessary to provide: employment policy measures in the regions of the country on the basis of public administration. Formation of monitoring and forecasting of territorial labor markets as a basis for determining the needs of regional organizations in the labor force, the volume and structure of their training in the UPR and successful employment in the profession (specialty). Analysis of the balance of graduates of the UPR in the areas of their further study and work and justification of the volume and rational structure of training in institutions of secondary vocational education and higher education. Introduction of benchmarking into the activities of employment services by identifying and implementing the highest standards of public services in the field of training of qualified young professionals. The paper reveals that the whole complex of works to determine the needs of the regional economy can provide the following procedure for the formation of the state order for the training of skilled workers and specialists: at the municipal level - interaction through a system of contracts between UPR, employers, employment services to determine the volume and profiles of training of skilled workers and professionals agreed with the district administration (city); at the level of subjects - the interaction of education management, labor and employment, employers «associations, the administration of the subject of the Russian Federation, formed volumes and profiles of training, taking into account the characteristics of the regions are subject to approval by the administration of the subject of the Russian Federation.

The article deals with the analysis of inverse relations as a research method. This method is used to analyze educational systems. Inversion is rendered as a position in a hierarchical system where the lowest element takes on a dominant meaning in it. The opposite state corresponding to the original relations in the hierarchy is denoted as the order relations. The order in the hierarchy is provided by the action of some organizational principles. Inversions result from the collision of two or more of these principles with each other. As a result, there are internal stresses in the hierarchy that can destroy this system. However, in some cases, these stresses can be useful, because they prepare the next step (aromorphosis) in the self-development of the system, Developed inversions are built into the system and can not be removed from it without devastating consequences. In the field of education, the analysis of inversions has several implications. First, it is necessary to create educational systems for the correct goal setting. The analysis of inversions shows the impact of education on the situation in the social hierarchy. Inversions are manifested directly in the structure of educational activities. This aspect is considered in the article in details. For example, in educational activities inversions are manifested in educational games. In the game, the process of activity becomes more important than the result. Game activity in education remains effective as long as it occupies a niche assigned to it. Inversions are also manifested when the results of control in education are brought to the fore. In this inversion manifest destructive properties. If the controlling activities in teaching become dominant, the learning activity becomes cramming. In this case, the emotional response to the received training task becomes more important than the desire to achieve the goal in its implementation. Thus, the analysis of inversions in hierarchical systems is a very relevant and effective method of research, allowing to identify systemic contradictions. This method is particularly promising in relation to educational systems .

The paper analyzes the relation between condition and prospects of Russian education development and security based on valuable content. The author makes a case that theoretical basis of security educational space that could be developed by the synthesis of geophilosophical theories based on the concept «geopolitical space of social relations» allows to see the benefits of diverse directions of the modern philosophy of education from the axiological point of view. Methodology and research methods are based on multivectoral methodology: gnosseological (principles of cognition); axiological (principles of educational values) and some branches of philosophical knowledge (philosophy of geopolitics, social philosophy, the world approach, philosophy of education, etc.). All this addresses some of the problems appeared in Russian education and security on the basis of beliefs and a number of organizational and educational measures. The research results show that security of social relations is considered in frames of spatial and -temporal dimension where the author highlights the educational system in terms of loss of autonomy, trim the humanitarian sphere, depending on public educationalpur- poses, etc. For public life and Russian educational space the focus is shifted on the threat of axiological content. The author addresses the social philosophy of basic scientific concepts like geophilosophy, geophilosophy of security, geophilosophical approach, geopolitical science and world analysis. Modernization theory, which ideologically inspired educational reforms, does not meet the macro-and micro-sociological processes in world space of social relations and could not serve as a reliable tool for Russian security educational space. From the loss of their position in the world system of States Russia can save only best value oriented education strategy, which not only central but also the extensive Russian periphery will develop intensively.

Introduction. Broadcasting of various life forms - biotic and social - is carried out using heredity mechanisms. But as the scientists of the XIX century showed, in the organic and social nature these mechanisms are qualitatively different. In the second half of the twentieth century, the mechanisms of social inheritance began to be actively studied. At the turn of the XX-XXI centuries, research in this direction is resumed, but taking into account the qualitative transformations of society. The article aims to: based on the analysis of the potential of knowledge developed in the twentieth century, identify new approaches to the study of the problem at the beginning of the twenty-first century in the context of the development of informatization and digitalization. Methodology and research methods. Dialectical and system-philosophical methodology; evolutionary, historical, socio-genetic, sociocultural, comparative research methods, integration of results. Results. It is shown that studies of the last century clearly identified the problem of finding mechanisms of social heredity, patterns of social inheritance. A relatively autonomous study of issues of social continuity as a permanent process. In our century, there are qualitative changes in the mechanisms of transmission of anthroposocial experience in Russian society. This is the acceleration of social processes; violation of the permanent connection of social inheritance and continuity in connection with the liberalization of social relations; simultaneous changes at the level of man and society. The processes of informatization and digitalization contribute to the acceleration not only of the transmission of anthropo-social experience, but also of its deformation, up to interruption based on the methods of manipulating information and consciousness of the subjects. Conclusion. At present, the problem of social heredity should be broader: as anthropo-social inheritance, continuity in the traditional, socio-economic, spiritual, cultural and educational aspects. Take into account not only the unidirectional positive transmission of anthropo-social experience, but also its possible deformation using the latest information technologies.

Nonlocal equations of the coagulation theory are studied by methods of group analysis. In addition to the integrodifferential Smoluchowski equation, equivalent models are also considered, including the equation for the Laplace transform of the original equation, an infinite system of equations for the power moments of its solution, and the equation for the generating function of the power moments. Admissible Lie groups for the considered equations are found, their relationships are studied, and the corresponding invariant solutions are analyzed.

Horizontal shear motion of a homogeneous fluid in an open channel is considered in the approximation of the shallow water theory. The main attention is paid to studying the mixing process induced by the development of the Kelvin-Helmholtz instability and by the action of bottom friction. Based on a three-layer flow pattern, an averaged one-dimensional model of formation and evolution of the horizontal mixing layer is derived with allowance for friction. Steady solutions of the equations of motion are constructed, and the problem of the mixing layer structure is solved. If bottom friction is taken into account, the mixing process becomes slower and the width of the intermediate mixing layer does not increase. Verification of the proposed one-dimensional model is performed through comparisons with available experimental data and with the numerical solution of the two-dimensional equations of the shallow water theory.

The classical Boussinesq equation describing gravity waves in shallow waters is under consideration. Hirota's bilinear representation is used to construct exact solutions describing wave packets, waves on solitons, and «dancing» waves. The principle of multiplying the solutions of the Hirota equation is formulated, which helps constructing more complex structures made of solitons, wave packets, and other types of waves.

A fundamentally new unsaturated technique for the numerical solution of the Dirichlet-Neumann problem for the Laplace equation was designed. This technique makes it possible, due to the smoothness of the sought solution of the problem, to take into account the axisymmetric specificity of the problem, which prevents the use of any saturated numerical methods, i. e., methods with a leading error term.

Variational approach and sensitivity theory methods are used to construct algorithms for solving the problems of environmental forecast and design. The behavior of the model in a parameter space is studied by calculating sensitivity functions as partial derivatives of target functions with respect to the model, used to investigate the properties of mathematical models and solutions of inverse problems. Not only the proposed approach implies the atmospheric quality model in a Novosibirsk agglomeration and an algorithm based on an ensemble of sensitivity functions, but is also used to solve the inverse problem of position estimation and pollution source intensity.

In the last decades, besides the comparatively well-studied “bloom” caused by phytoplankton, a “bloom” of marine and fresh waters caused by littoral benthic macroalgae of three genera: Ulva , Cladophora and Spirogyra have become a global phenomenon. In the present review, an attempt is made to approach a comprehension why namely these taxa of green filamentous algae start to grow rapidly in spring in many water bodies and streams, including oligotrophic waters, and then float up from bottom forming floating mats (metaphyton), and their decaying masses are washed ashore and cause substantial ecological and economical losses. Peculiar and common ecological and physiological features of Ulva , Cladophora and Spirogyra favorable for the “green tides” formation are considered. Although an eutrophication (supply of nitrogen and phosphorus from agricultural lands, industrial and domestic wastewaters, aquaculture) is the evident cause of the increase of algal biomass, a hypothesis is proposed that a location of external fluxes of inorganic nutrients (surface runoff or groundwater discharge) is of the key importance for the “green tides” formation, as well as a biogenic re-direction of internal fluxes of nitrogen and phosphorus from pelagial to littoral (benthification). Measures of mitigation of “green tides” are discussed. A necessity of detailed study of metaphytonic form of vegetation of benthic macroalgae is emphasized. It is remarked that a revision of the present concept of oligotrophic/eutrophic waters, which considers only pelagic compartments of aquatic ecosystems is needed.

The available literature data and materials of own research of 14 mineral and 19 thermal springs of the Lake Baikal region conducted in 1997-2017 are summarized. Soil profiles were made, samples of water, algae, lichens, mosses, vascular plants, qualitative and quantitative samples of zoobenthos were collected. The soils in the area of springs have a short profile and chemical composition corresponding to the water chemistry, they are named “parasoils”. Two hundred fifty seven species of algae were found in mineral springs, most of them (196 species) belong to the diatoms. The lichen flora proved to be non-specific. In the mineral springs 7 species were found, in the surroundings of the thermal springs 100 lower taxa were collected. In the mineral sodium chloride springs 6 types of communities of zoobenthos were distinguished according to the dominant in biomass group of the macroinvertebrates: Gastropoda-like, Turbellaria-like, Chironomidae-like, Amphipoda-like, Psychodidae-like and Ephydridae-like. In thermal springs 4 types of communities of zoobenthos were ascertained: Gastropoda-like (with division into mono-, two- and three-dominant), Odonata-like, Amphipoda-like and Chironomidae-like. High levels of biomass appropriate to the eutrophic and hypertrophic lakes are for the most part characteristic of thermal springs. The species status of endemic to high-thermal springs mollusk Lymnaea thermobaicalica is confirmed.

The paper presents results of study of autochthonous bacteriophages - previously unknown element in the structure of the “microbial loop” in the ecosystem of deep oligotrophic Lake Baikal. Transmission electron microscopy method was applied to study morphological diversity of phages in the water column, surface microlayer and benthic biofilms at the water-rock (marble, granite, mica, quartz, amphibolite, gabbro, urtite) interface. Data on the size structure of the autochthonous bacteriophages, their quantity, seasonal dynamics and vertical distribution from the surface to the maximum depth of 1200 m in comparison with bacteria are given. A few morphotypes of Baikal autochthonous bacteriophages affecting Pseudomonas aeruginosa are isolated and characterized by means of molecular and genetic methods. Full genomes of a gigantic phage PaBG of the family Myoviridae and MD8 of the family Siphoviridae are determined.

The results of a multi-year study of plankton algae and invertebrates in drainless saline lakes of the Uldza-Torey basin are presented. The plankton communities transformation due to climatic fluctuations was characterized by multidirectionality. The influence of abiotic environmental factors (water level, salinity, pH, water temperature) on the composition, structure and abundance of hydrobionts was estimated.

The algorithm of dynamic mass-balance simulating a biotic energy flow in planktonic community containing the microbial organisms has been developed. Inlet parameters of the model are latitude, mean depth of the water body, total phosphorus content and water colour. Biomass and production of the key plankton group are predicted by the model. It is shown that a food base for fish and fish growth depend on extent of protozoan plankton contained in food web.

The estimation of the current ecological state of the Sivash Gulf (the southern part of the Eastern Sivash) was conducted in the conditions of its water regime changes. According to the obtained concentrations of the main pollutants classes, the prevailing type of anthropogenic impact on the ecosystem state of the investigated water area is a reduction in the freshwater runoff. It caused a rise in the salinity of the water. The quantitative indices of the microbial community of sea bottom sediments of the bay characterize their contamination by organic substances. The increase of salinity in the basin caused restructuring of the bottom community main components. Meyo- and macrozoobenthos manifested decrease in biodiversity indicators and change in the taxonomic structure of the biocenosis.

Data on species diversity of Micrasterias C. Agardh ex Ralfs representatives from the water bodies of West Siberia, their occurrence in zones and subzones are generalized. To date 23 specific and intraspecific taxa from the order Desmidiales are known. The representatives of the family occur in mosaic order in all the area of West Siberia. The greatest number of taxa (15) was revealed in middle taiga, significantly less was determined in southern and northern taiga, 9 and 8 taxa, respectively, and 3-5 in other zones. No species were discovered in the steppe zone. Thirteen species (18 taxa) of the genus were found in the lakes of different types, 5 species (7 taxa) in water streams, 4 (5 taxa) in swamps, and 4 species in temporal water bodies. The analysis performed on adaptation of the species to habitat conditions has shown that the representatives of this genus may serve as indicators of acid and brackish water. With relation to mineralization prevail halophobes - 11 taxa, among indicators of pH prevail acidophilous plants - 15 taxa.

Numerical modeling results on growth of axially symmetric hydraulic fracture new free surface in isotropic poroelastic medium are presented. The problem was solved using extended finite element method based on phantom nodes and cohesion model of failure. Trajectories of the fracture are calculated for different distances from free surface under injection of certain volume of working fluid with regard to the fluid leakage. The influence of impermeable boundary on the hydraulic fracture growth is analyzed.

Based on the uniform strength and minimized stress intensity factor, the maximum strength shape of an opening in rock mass is theoretically analyzed. The criterion and solution method are proposed for the problem on prevention of failure in rock mass with opening under the action of tectonic forces and gravity. The constructed closed system of algebraic equations enables minimization of stress intensity factors depending on mechanical and geometrical parameters of rock mass.

The results of numerical modeling of intense shock wave propagation after explosion in a mine opening with permeable barrier are presented. The problem is solved in the equilibrium inviscid formulation without regard to chemical reactions and with averaged composition of mine air. It is shown that for a screen composed of four similar permeable barriers arranged as a labyrinth, the incoming shock wave has a strongest impact on the first barrier. As a consequence of weakening of the shock wave front on the first barrier, the rest barriers experience much less loading. In order to decrease peak loads on a load-bearing metal structure, it is necessary to reduce areas of their flat front surfaces.

In order to meet the increasing demand to coal, longwalls having large working heights up to 7.3 m are being operated worlwide. As the working heights increase, the load-bearing capacities of powered roof supports used at such longwalls are to be raised too. From a powered roof support it is expected that it safelybears the roof loads and transmits them to the footwall at different working heights. This article presents the results of numerical analyses on roof stresses at different longwall working heights. In order to determine the most suitable longwall working height, average stress distributions that occur on roof and gob zones are calculated for different longwall working heights. For this purpose, numerical models are built up and the procedure is applied to a real-life underground coal mine. Six distinct longwalls are modeled considering rock mass properties and working heights. In conclusion, the most suitable longwall working height for the mine under study is determined considering stresses occurring on roof strata and the gob zone.

The determination of the grain size distribution of blasted rock exceeds the capability of an analytical sieving machine which only gives reliable results within a range of 63 µm to 125 mm. Other sophisticated methods are often not available for particle size measurement in coarse-grained applications in medium scale mining. Therefore, an alternative low cost method to investigate the grain sizes of blasted rock is introduced which can cover a range from 63 µm at the lower end without an upper limit. Three different options to examine blasted dolomite grains are investigated and combined with sieve analysis to determine a complete sieving equivalent grain size distribution. Comparison with results of a technical sieving shows that this method gives a good approximation of the size distribution, improving the possibilities for design of mineral processing equipment.

Accuracy of breakstone grain-size analysis using digital images in the initial method and its modification based on algorithm proposed by Rubin is compared. A modification with averaging of features over all directions and the method with a classification feature represented by difference of intensity distribution functions of fragment projections are described. The results obtained using these methods in a series of tests on grading of five breakstone fractions measured in a certified laboratory. It is shown that the modified method by Rubin with averaging over all directions provides the highest accuracy.

In a transportation fleet in open-pit mines, the match factor is defined between loading and dumping vehicles. This factor helps in indicating the number of vehicles that depend on each other. In this study, a new parameter termed the “detailed match factor” is developed to improve the transportation fleet and relationships are deduced to control the production and grade. A transportation fleet model was simulated for a typical iron ore mine and was solved using both the detailed match factor and ant-colony algorithm methods. The detailed match factor helped in increasing the production by 10.6%

Using inverse distance weighting (IDW), the model of a coal seam with distributed geological and geomechanical characteristics is developed. The hyperbolic dependences of the cutter-loader advance feed and capacity on the coal seam thickness are found. Influence of coal face spalling on cutter-loader capacity is assessed. Using the specialized library of MTSS, the integrated model of process flows in coal face area is developed. It is found that there exists cutter-loader capacity maximum at the increasing dependence of coal cuttability on longwall length.

Backfilling mixture preparation technology using a cement-slag binder is developed for Artem mine. It is shown that backfill with granulated blast-furnace slag reaches project strength when slag is to 80% milled down to 80 μm. The authors analyze influence of milling fineness of granulated blast-furnace slag from different manufacturers on strength and rheological properties of backfill. The economic analysis of cost of binder in formation of load-bearing layer of backfill prepared using fly ash and milled granulated blast-furnace slag is performed.

Various-rank tectonic structures are distinguished in the Norilsk Region. The first-order block structure is formed by intersection of rank I geodynamically active faults: Khatanga, Imangda-Kystykhtakh, Norislk, Fokin-Tangaralakh and other. Rank II faults are the Norilsk-Kharaelakh fault, which intersects the mine field, and other 7 structures. Using geological sections and boring records obtained within the mining lease, dip slips and oblique-slip faults of rank III, represented by ridges in the terrain, are plotted in the satellite image. In the rockburst-hazardous high-grade ore sites in Glubokaya mine, it is recommended to make safe zone by advance boring of destressing holes in underground openings in zone of rank III faults.

Predicting the consequences of changes in a system such as the system of exploitation and consumption of limestone is a problem that requires an adequate analytical approach and encompasses all the limiting factors, their performance, dependence, desirable and non-desirable changes, and completion of the set goal or multiple goals. Without forming the mathematical model and applying the adequate solving method, it is not possible to solve the problem on the optimal level. This paper shows the linear model of location exploitation optimization and consumption of limestone in Macedonia, with 29 production entities - open-pit mines, and two options of consumption entities, with 15 and 16 lime consumers. By changing one of the starting presumptions, the number of consumers, the research shows that mathematical model approach with adequate sensitivity to changes of relative parameters is necessary for a complete and reliable overview of system behavior.

The resource-saving technology is proposed for mining watered lignite deposits in the Kansk-Achinsk basin without drying of productive strata. The expediency of accumulation of all water inflows in mined-out area of the open-pit mine for the subsequent use in the closed production cycle is substantiated. Effectiveness of hydromechanization in selective stripping of incompetent overburden rocks with solid inclusions is determined. Parameters of a hydraulic fill placed in the mined-out area of the open pit are presented.

Slope stability is “the heart” of open pit mining operations. Pit slope monitoring is an important undertaking requiring collection of structural data for geotechnical characterization and stability analysis. Challenges exist with conventional field data collection methods including time, safety, and data accuracy and reliability. In this paper, 3D laser scanning, photogrammetry and Split FX are integrated to investigate open pit slopes in highly geologically altered materials using a case study from the Melbur Pit slopes in Cornwall, United Kingdom. A 3D laser scanner is applied to scan structures from the slope face and to create a 3D point cloud database. Photogrammetry is applied to capture images for processing. 3D images are draped onto the point cloud to give a visual representation of the slope face. The kinematic analysis indicates that the integrated approach enhances the identification of structural discontinuity sets and their orientations. An integration of emerging digital technologies thus provides a comprehensive and reasonably reliable structural database for slope stability analysis during open pit mining.

The procedure is developed for modification of diamond surface by luminophore-containing organic compositions. The compositions are composed of an organic luminophore-anthracene, inorganic luminophore K-35 and cetane. Indication compositions are synthesized based on the selected luminophores and organic liquids and tested using pilot separator POLYUS-M. Spectral-kinetic characteristic of luminophopre-containing organic-mineral compositions, treated weakly luminous diamond crystals and kimberlite minerals are determined. The compositions ensuring better spectral-kinetic characteristics and higher extraction of diamonds during H-ray luminescence separation are selected.

The operating and promising apatite deposits in the Murmansk Regions, holding 70% of Russia’s phosphate ore reserves being unique feedstock for the production of mineral fertilizers are reviewed. The causes of reduction in P₂O₅ content of produced ore, which lead to higher cost of concentrate production and to increased volume of waste, are shown. It is found that it is efficient to stabilize the processing feed through preconcentration of apatite ore by means of coarse X-ray luminescence separation that elevates P₂O₅ content of process flow owing to removal to 20% of material with P₂O₅ content to 2%. The semi-commercial tests reveal destabilizing factors which lower the separation circuit efficiency. Elimination of these factors by adjusting velocity and motion path of coarse ore between the zones of measurement and separation allows minimization of useful mineral loss in waste by more than 2 times, which improves selectivity of X-ray luminescence separation and increases extraction of P₂O₅ in concentrate.

The process of fluid mass transfer and formation of concentration zones on evaporation barrier in rock mass are studied. A series of experiments is carried out on a special testing plant in order to examine the process of settling-down on evaporation barrier and to determine parameters of vertical zonality in settling-down of simple and complex water-soluble nonferrous metal salts. The experimentation procedure is described. The regular patterns are found in the change in content in the direction toward the surface across the whole zone of aeration from the groundwater table. The higher salt concentration is observed on the rock mass surface, in the upper salt crust. This distribution law is typical either of simple or complex salts. The main parameters of settling kinetics and evaporation rate on the barrier are revealed and evaluated.

The process of wet magnetic separation of oxidized ore from the deposit of Abail, Republic of Kazakhstan, is studied. Kinetics of roasted product milling is analyzed, and the optimal size is recommended for the fist stage of milling as -0.071 mm at the content of 55-60%. The accomplished magnetic analysis of different size products shows that the decrease in size causes no increment of iron in the magnetic product and iron is at the level of 63.0 mass%. The scanning electron microscopy reveals that the roasted and magnetic products contain floccules of gangue and magnetite particles which ass into magnetic fraction and worsen its quality. Two schemes are proposed for decomposition of floccules: multistage desliming with regard to sedimentation velocity in liquid medium and attrition with deffloculation agent. It is recommended to apply two two-stage circuit with milling, desliming and wet magnetic separation, which allows production of iron concentrate with iron content of 67% at recovery of 76.5%.

The results of the mineralogical examination if of old sulphide and oxidized gold ore tailings of a mining and processing plant in the Krasnoyarsk Territory are presented. Secondary mineral forms of antimony, namely, antimony bloom Sb₂O₃ and tripuhyite FeSBO₄, as well as iron are found. Gypsum in the waste is a newly formed phase, undetected in the initial ore, revealed in sulphide and mixed ore tailings and is absent in oxidized ore tailings. The key valuable component is gold represented by fine accretions in arsenopyrite, free gold size is not more than a few first microns.

Modeling of heat exchange processes in water-saturated rock mass during shafting with artificial freezing is performed. The problem of adjusting thermophysical properties of rock layers by the experimental measurements of temperature in the check thermal wells spaced from the freezing perimeter is analyzed. In terms of the abuilding shafts at Nezhinsky Mining and Processing Plant, significance of adjusting the the thermophysial parameters borrowed from the geological engineering survey data is illustrated. The number of independent adjustment parameters is determined from the analysis of the system of equations in two-dimensional two-phase Stefan problem in the dimensionless form. An inverse Stefan problem is formulated for a horizontal layer of rocks. The numerical algorithm is proposed for the inverse Stefan problem solution based on the gradient descent method. The algorithm minimizes functional of discrepancies between the model and measurement temperatures at the locations of the check wells. The functional of discrepancies in the phase space of the thermophysical properties and the algorithm convergence are analyzed.

A review of various real time temperature devices available for use in underground coal mines in Queensland was conducted. To investigate the fit-for-purpose of the intrinsically safe (IS) instrument, laboratory experiments were performed. The obtained results were compared to the calibrated reference instrument readings and sling psychrometer data under variation in air flow velocity, moisture content and dust content.
