AP19677938 “Developing a method of predicting the enclosing rock displacement to the earth’s surface to modernize the technology of re-mining flat ore deposits”, p.m. Takhanov D.K.
Relevance
Predicting the earth’s surface subsidence when undermining, represents an urgent problem in the development of mineral resources associated with the negative impact of the displacement process on undermining buildings, structures, utilities and natural objects. The problem has become more important in the last decade due to the involvement in the re-mining of abandoned mineral reserves in support pillars.
Despite the large amount of theoretical and experimental research to assess the effect of the applied mining system of the structural elements state and the thickness of the enclosing rocks on the parameters of deformation of the earth’s surface, there is still no final scientifically based approach to the effective design of technological parameters for mining ore deposits. The generally accepted method of calculating displacement parameters includes calculations based on the analysis of field observations and presentation of empirical patterns for specific fields, which is not always applicable to other similar fields.
Therefore, the problem of increasing the efficiency of ore deposit development, taking into account the prediction of the displacement of host rocks to the earth’s surface to ensure complete extraction of minerals, is an important task from a practical and scientific point of view, the solution of which allows one to reduce the cost per unit of extracted mineral.
Based on the analysis and review of the state of the issue, the purpose of scientific and applied work is formulated.
The project purpose
The purpose of the project is to improve the technology of re-mining flat ore deposits based on a reliable predicting the movement of rocks and the earth’s surface by studying patterns and identifying factors that determine the limits of the deformation zone limited by sliding surfaces.
Expected and achieved results
According to the schedule, research was carried out to ensure the completeness and quality of the re-mining of flat ore deposits, taking into account the geomechanical state of the overlying rock mass and the earth’s surface. A complex of theoretical and field studies is currently being carried out, including assessments of the parameters of the earth’s surface displacement and the defectiveness of mined-out spaces.
Based on the actual results of the displacement of the overlying strata above the previously mined re-mining panel 2, the parameters of the angles of displacement of the overlying strata were determined for the conditions of the Zhomart mine (ν = 107°; β = 73°; γ = 73°, δ = 73°; γ’ = 90°; β’=90, δ’= 90°).

AP19675471 “Developing a technology of synthesizing composite ceramic materials of the AlxFeySi system using the additive method”, p.m. Andreyashchenko V.A.
Relevance
The use of aluminum alloys has an undeniable advantage over many other alloys, primarily due to their low weight, good performance properties, high electrical conductivity, anti-corrosion properties and sufficient mechanical characteristics. However, to achieve a high level of these characteristics, alloying with expensive, usually rare earth, elements is required. This approach leads to a sharp increase in the cost of finished parts. MeSi type ceramics (silicides) have high hardness and wear resistance. To solve the problem of improving the quality of aluminum-based parts, it was decided to develop a composite ceramic material AlxFeySi. The uniqueness of the material lies in the possibility of forming the Al8Fe2Si phase, which has a highly symmetrical crystal lattice, ensuring the ability of the resulting composite ceramic materials to perceive plastic deformation.
The project purpose
To develop a technology of synthesizing composite ceramic materials of the AlxFeySi system using the additive method to improve the quality of the materials structure and parts based on them.
Expected and achieved results
Future results in 2023. A complete list of alloying elements and their percentage content will be determined based on the principles of economical alloying, and a phase and thermodynamic analysis of the synthesized composite will be performed. Preparing charge materials for the synthesis of composite material will be carried out: crushing and grinding of alloying components, classification by size, fractional analysis. The composition of the flux will be selected to exclude interaction of the charge materials with the surrounding atmosphere and its preparation will be carried out. Synthesis modes will be empirically selected and mathematical dependencies characterizing the process of obtaining the composite material will be obtained. The authors will take part in an international conference with the publication of a report.
Results achieved in 2023. Alloying elements that expand the range of existence of the Al8Fe2Si phase were identified, a complete list of alloying elements and their percentages were determined based on the principles of economical alloying. A phase and thermodynamic analysis of the synthesized composite was performed. The completion form is the thermodynamic and phase analysis in ThermoCalc software.
The main alloying elements of the Al-Fe-Si system include copper, nickel, magnesium, chromium, manganese and boron. The introduction of alloying elements in amounts up to 1% is considered, guided by the principles of economical alloying. It was revealed that these alloying elements contribute to a change in the temperature limits of the formation of the highly symmetrical Al8Fe2Si phase, the addition of copper leads to a decrease in the lower limit of formation, nickel, on the contrary, increases both the lower and upper limits, while for all the elements considered, the phase is observed at an iron content of no more than 35% . Manganese expands the boundaries of the existence of the Al8Fe2Si phase.
The preparation of charge materials for the synthesis of composite materials was carried out: crushing and grinding of alloying components, classification by size, fractional analysis.
A differential thermal analysis of the charge materials was performed and thermograms were obtained. There were studied 10 compounds with duplication of each experiment at least 3 times. A comparison of thermograms with phase diagrams showed that the endothermic effects observed in the thermogram coincide with the temperatures at which the liquid phase begins to separate.
Mechanical alloying and compaction of the charge were carried out taking into account the required ratio of components, dosing and packaging.
The composition of the flux was selected to exclude the interaction of the charge materials with the surrounding atmosphere. Its preparation has been completed. A granulometric analysis of the flux was performed.
The welding and technological properties of fluxes for arc welding and surfacing are determined by the following indicators: – high stability of arc combustion; – high-quality formation of a seam with a smooth transition to the base metal; – low tendency to form pores and cracks; – good separability of the slag crust. Based on data on gas permeability, composition of fluxes and their purpose, two welding fluxes were selected for research: AN348 and AN60. Thermogravimetric analysis was carried out with verification of the results by X-ray phase studies of three groups of samples: charge, charge with flux, flux. Within the groups of samples, the fractional composition of the flux, the amount of flux, and the type of flux varied. Based on experimental data, a flux composition was selected that excludes interaction of the charge materials with the surrounding atmosphere. AN-348A flux showed a greater efficiency. Therefore, for further experiments on surfacing, AN-348A flux was adopted.
The synthesizing modes were empirically selected and mathematical dependencies were obtained that characterize the process of obtaining the composite material. The main technological conditions that ensure the efficiency of the synthesis of metal-ceramic material using the additive method have been identified. The following were identified as the main technological factors: 1. Method of laying the charge; 2. Current value; 3. The ratio of the thickness of the charge, the thickness of the electrode, the amount of flux; 4. Particle size and chemical composition of the flux; 5. Fractional composition of the charge. The influence of the following technological factors was studied with various options of laying the charge: between the base and the electrode, on the electrode, pre-compacted charge and uncompacted charge, different ratios of the amount of charge and its placement; the influence of the thickness of the charge, the electrode and the amount of flux on the synthesis of metal-ceramic materials was studied, the influence of the mode (magnitude of currents) on the process of material synthesis, the influence of the granulometric and chemical composition of the flux was revealed, the influence of the fractional composition of the charge and flux, the influence of the size of the gap between the electrode and the base on the formation arcs. A technology has been developed for the synthesis of composite material components using the additive method. For the first time, a metal-ceramic material of the Al-Fe-Si system was obtained by surfacing with a consumable electrode. For the first time, a metal-ceramic material of the Al-Fe-Si system was obtained by powder-bed surfacing.

AP19678770 “Radioecological aspects of radioactivity of thermal coals and ash and slag wastes in the context of their impact on the environment”, p.m. Pak Yu.N.
Relevance
The relevance of the results is associated with studying radioecological aspects of natural radioactivity of thermal coals and ash and slag waste in the context of their negative impact on the environment.
The radiation hazard associated with natural radioactive elements contained in coal is one of the important problems of coal energy, which is underestimated in Kazakhstan. To reduce the exposure of personnel and the population living in the areas where coal-fired thermal power plants are located, systemic monitoring of radioecological safety is necessary. Existing radiation safety standards are limited to the content of radionuclides only in ash and slag waste when used for construction purposes.
The project purpose
The purpose of the project is to assess the impact of using coal containing natural radioactive elements in the fuel energy industry on the radioecological situation of the environment.
Expected and achieved results (2023)
The features of natural radionuclides of uranium, thorium and potassium distribution in thermal coals, their specific activity and forms of their occurrence depending on the grade of coal and its quality (ash content) were studied.
A sufficient number of selected representative samples and specimens, the data of the specific activity of each radionuclide, obtained on the basis of their analysis by modern nuclear radiometric, radiochemical and x-ray methods, were determined.
A model of the behavior of natural radionuclides during coal combustion at thermal power plants and a methodological basis for assessing the impact of the use of coal containing natural radioactive elements in the fuel energy sector on the radioecological situation in the natural environment were determined.

AP19680292 “Developing an expert decision-making system on issues of supporting and maintaining mine workings”, p.m. Tomilov A.N.
Relevance
The main difference of the created software product is the use of both heuristic and algorithmic methods, which allows us to give the most optimal query results.
An expert system knowledge base contains rules (or other knowledge representations) that are used as a basis for decision making. The inference mechanism contains general knowledge about the problem-solving control scheme. This mechanism contains two components: an interpreter and a dispatcher. The first of them determines how to apply the rules to derive new knowledge, and the second sets the order in which these rules are applied. The knowledge base editor is designed to modify the rules of the expert system, as well as to enter new knowledge into the expert system.
The project purpose
The purpose of the project is to develop a domestic expert system aimed at presenting decisions on the issues of securing and maintaining mine workings using both heuristic and algorithmic methods, which allows us to give the most optimal query results. The placement of the knowledge base and the main software of the expert system is expected to use cloud technologies.
Expected and achieved results
The main result of the project is the creation of a domestic expert system aimed at presenting decisions on issues of securing and maintaining mine workings using both heuristic and algorithmic methods. To host the knowledge base and the main software of the expert system, it is assumed that cloud technologies will be used. The result of using the expert system will be the proposal of optimal parameters of various types of support for any sections of mine workings, parameters and methods of protecting mine workings, determination of destruction zones in the vicinity of workings, taking into account changes in mining-geological and mining-technical conditions for the development of mineral deposits, taking into account the time factor, allowing to determine expected displacements and loads. The modular structure of the expert system assumes further expansion to solve a wide range of geomechanics problems.

АР19678453 “Institutional regulation of preventing interethnic conflicts among students in the conditions of socio-cultural transformation of Kazakhstani society”, p.m. Shormanbayeva D.G.
Relevance
For Kazakh society, as one of the most multicultural and polyethnic in the modern world, international communication is not just a term, a category for scientific research, but a vital component of civilizational security. Modern Kazakhstan has developed as a multi-component society and at the beginning of the 21st century continues to solve the issues of integration of ethnic groups into the Kazakh political nation.
The movement of Kazakh society towards a new quality of life along the path of development of world civilization is impossible without internal stability and consolidation, preservation and strengthening of international harmony at all levels of relations. Changing the paradigm of our country’s development in this plane is indicated in the Message of the Head of State Kassym-Jomart Tokayev to the People of Kazakhstan “New Kazakhstan: the path of renewal and modernization”. This project is aimed at implementing Task 1 “Development of Kazakh identity and intellectual potential” of the National project “National spiritual revival”.
Student youth is a socio-demographic group that is in the process of formation and development of socio-cultural and civic maturity. Weak involvement of young people in the system of social relations, preservation of attitudes and stereotypes of the previous generation cause them to gravitate towards identification and isolation, conformism and negativism. That is why it is necessary to pay special attention to interethnic interaction among youth.
Scientific research is focused on the prevention of interethnic conflicts in Kazakhstan and their prevention through the mechanism of institutional regulation, which in our opinion is one of the most effective ways of forming tolerant attitudes, values of solidarity and mutual respect.
The project purpose
Developing effective ways of institutional regulation of prevention of interethnic conflicts among student youth in the conditions of socio-cultural transformation of Kazakh society through the system of education and public organizations.
Expected and achieved results
- Updated methodological basis of institutional regulation of interethnic relations for conducting scientific research. The conceptual apparatus of interethnic relations is concretized. Argumented methodological basis of the sociocultural approach as relevant for the analysis of institutional regulation of interethnic relations. The work has been completed.
- The causes of inter-ethnic conflicts among student youth in the conditions of socio-cultural transformation of the Kazakh society are revealed and analyzed in order to determine the level of inter-ethnic tension.
There have been determined the causes of inter-ethnic conflicts among student youth in the conditions of socio-cultural transformation of the Kazakh society to determine the level of inter-ethnic tension by the sociological survey method. the main indicators of the causes of growing tension and conflict potential in the interethnic aspect are determined. An analytical report was prepared based on the results of a sociological study of the causes of interethnic conflicts among student youth in the context of sociocultural transformation of the Kazakh society. Determined causes of inter-ethnic conflicts among student youth in the conditions of socio-cultural transformation of the Kazakh society to determine the level of inter-ethnic tension by the sociological survey method. the main indicators of the causes of growing tension and conflict potential in the interethnic aspect are determined. A sociological study of the causes of interethnic conflicts among student youth in the context of sociocultural transformation of the Kazakh society was conducted, in which 1,500 representatives of student youth took part in the full territorial coverage of the Republic of Kazakhstan. According to the results of the study, the following causes of interethnic conflicts among student youth were revealed: the influence of ethnicity and language on the level of life satisfaction; insufficient level of political culture of student youth; the absence of a unified university policy to preserve interethnic harmony; a low level of education in terms of social perception and tolerant education; negative influence of social networks. The work has been completed.
- There have been revealed primary attitudes of student youth of the Kazakh society on the subject of determining correlations between: ethnic identity and intrapersonal conflict; tolerance, agreement and mutual understanding by ethnos and values; expectations and attitudes from the educational process, university education, profession and their implementation in practical life.
An analytical report was prepared based on the results of a sociological study of the causes of interethnic conflicts among student youth in the context of sociocultural transformation of the Kazakh society. As a result of the analysis, a high correlation between ethnic identity and intrapersonal conflict was revealed. As the results of the study show, the values of such variables as knowledge/insufficient knowledge of the language of the ethnic group, knowledge of norms, values, and culture of the ethnic group allow us to confirm the existence of a statistical relationship between ethnic identity and intrapersonal conflict. Within the framework of this study, a positive correlation was revealed between the positive orientation of ethnic identity and a high level of tolerance, ego values. The results of the study allowed to reveal the discrepancy between expectations and attitudes of the educational process (policy in the field of maintaining interethnic harmony among student youth in the university/college; attitude among the teaching staff, administration of the university/college), which contributed to the increase in dissatisfaction among the student youth. The work has been completed.
- There have been identified effective ways of institutional regulation of prevention of interethnic conflicts in the student environment through the education system and public organizations: the Club “Unity of Culture” was organized; there was developed a digital platform “Cross-cultural dialogue”, educational and methodological support for prevention of inter-ethnic conflicts in the student environment.
- There has been determined the effectiveness of the developed ways of institutional regulation in the prevention of interethnic conflicts.

АР19679505 “Studying and developing algorithms for multi-threshold decoding of convolutional codes and their software and hardware implementation for high-speed radio channels with fading”, p.m. Sailaukyzy Zh.
Relevance
The study relevance is associated with implementing the tasks of the state program “Digital Kazakhstan”, the Law of the Republic of Kazakhstan “On National Security” and the State Cybersecurity Concept “Cyber Shield of Kazakhstan” to ensure information security and communication infrastructure, to maintain and to develop an effective system for protecting information resources and communication infrastructure. The development of the national radio communication system is an important component of national and information security, as it ensures interconnection between the services of special government agencies, the Armed Forces, law enforcement agencies, emergency medical services, fire and search and rescue teams.
Currently, high-speed reliable radio communication systems are implemented using orthogonal frequency division multiplexing technology, which allows for the required spectral efficiency and high data capacity. But with broadband wireless communication over long distances, many errors occur, which leads to the need to also use forward error correction methods. The idea of the project is to develop and implement in hardware and software effective error correction schemes for use in radio communication networks with fading, as well as in the presence of Doppler shift and intersymbol interference.
The project purpose is studying and developing error correction methods and tools that ensure operation close to channel capacity when used in rapidly changing digital radio communication systems in conjunction with orthogonal frequency division multiplexing technologies and multi-position modulation, space-time coding and precoding.
Expected and achieved results
- The work has been carried out to study the specifics of digital radio information transmission systems for mobile radio communication systems in the presence of fading, radio modems, radio systems for receiving video and audio information, the requirements used in the selection of noise-resistant coding methods based on the criterion of the maximum value of EIC, speed, complexity of software and hardware implementation have been determined encoders and decoders.
The basic principles of implementing an LDPC encoder are studied. Software and hardware implementations of encoding and decoding with hard decision algorithms with bit inversion based on mathematical models and algorithms have been implemented. Based on the simulation results, the error correction effect of LDPC codes using the Tanner graph for radio channels was analyzed.
Based on the results of these experiments, one publication was published – 1 (one) article in the proceedings of the VIII International Scientific Conference “Informatics and Applied Mathematics” (October 26 – 27, 2023, Kazakhstan, Almaty).
- There has been carried out the analysis of susceptibility of self-orthogonal codes to error propagation using multidimensional probability generating functions and using the Tanner graph of the code. The results obtained were used in the construction and selection of codes for use in multi-threshold decoders at a noise level that is only a few tenths of dB lower than the radio channel capacity.
A method has been proposed to reduce the effect of propagation of decoding errors based on the construction of self-orthogonal codes with a low degree of intersection of sets of control errors for various information symbols. An original program for modeling convolutional encoders was used with manual and automatic adjustment of code parameters, introduction of errors in the communication channel and optimization of iterative threshold decoding parameters. Simulation results showed that optimizing threshold values and weights for all threshold elements reduces the error propagation effect and error correction efficiency.
Based on the research results, they were accepted for publication in the 7th International Symposium on Innovative Approaches in Smart Technologies (November 23-25, 2023, Turkey, Istanbul).
- Studies have has been carried out on the effectiveness of multi-threshold decoding algorithms for convolutional codes for communication channels with fading. Modifications of the error correction circuit are proposed and justified by optimizing the operating parameters of a multithreshold decoder (MTD), new algorithms for the operation of individual functional units of the decoder, as well as cascading schemes, the constituent elements of which are multithreshold decoders.
An algorithm has been proposed for optimizing the parameters of multi-threshold decoding of symbolic self-orthogonal codes, which makes it possible to reduce the number of enumeration options several times while minimizing the decoding function and reduce the probability of decoding error by more than 2 orders of magnitude.
A new cascade coding scheme has been studied, consisting of two MTDs with varying coding parameters in a Gaussian channel. The probabilities of the probability of a decoding error in the area of efficient operation of a multithreshold decoder and the speed of software implementation of these concatenation schemes are estimated.
Based on the results of these experiments, one publication -1 (one) was published in a domestic publication recommended by the Committee for Quality Assurance in Science and Higher Education of the Ministry of Science and Higher Education of the Republic of Kazakhstan.
- To carry out theoretical and simulation modeling of the use of MTD in digital radio systems using multiplexing with orthogonal frequency division of channels and multi-position modulation.
- To develop methods of using MTD in systems with several transmitting and several receiving antennas, methods for assessing a radio channel using MTD.
- To develop methods of joint iterative demodulation/decoding to improve the energy efficiency of digital radio data transmission systems with MTD.
