AP23489856 «Development of Resource-Saving Ore Extraction Technologies Ensuring the Preservation of Mining Infrastructure in Regions with High Tectonic Activity» Project Supervisor – A. Mussin
Relevance
The relevance of the issue is linked to the need to enhance resource conservation during the development of mineral deposits and to ensure the preservation of mining infrastructure facilities located in regions characterized by high contemporary tectonic activity. The greatest risk is posed to mining facilities situated in mountainous areas, where processes of seismic energy release are still ongoing.
Intensive exploitation of mineral deposits, which in recent years has led to continuously increasing volumes of excavated space in rock masses and to greater depths of ore extraction, has resulted in the activation of geodynamic processes and phenomena within the rock mass and at the Earth’s surface. The most hazardous of these include: instantaneous rock failure and collapse of the roof and walls of workings due to elastic energy accumulated in block masses; disruption of aquifers accompanied by violations of the hydrodynamic regime of groundwater and subsurface waters; and destabilization of the ground surface.
Achieved Results
To assess the stability of underground workings, the study employed the limit equilibrium method, which is based on the analysis of force balance along potential failure surfaces. Unlike the classical deterministic approach, which operates with averaged parameter values, this work implements a probabilistic approach, allowing for the consideration of the natural variability of the geomechanical properties of the rock mass.
To enhance the reliability of modeling, a statistical combination of Monte Carlo methods and Latin Hypercube Sampling (LHS) was employed. This approach provides a more comprehensive coverage of the possible states of the rock mass and allows for a statistically justified distribution of the Factor of Safety (FS).
The research methodology integrates field studies of rock mass fracturing with numerical probabilistic stability analysis of the workings. The comprehensive approach includes fracture mapping, stereographic processing, and stability modeling using the limit equilibrium method, taking into account the variability of structural characteristics and strength properties.
This section presents the results of numerical modeling conducted using the Unwedge software package for the probabilistic assessment of wedge stability in underground workings. The analysis was performed for various excavation directions relative to fracture systems identified through structural core analysis. Dynamic effects, including seismic loads, were also taken into account. Special attention was paid to identifying critical excavation directions and optimizing support parameters to ensure stability under fractured and seismically active rock mass conditions.
Figure 1 – Results of the probabilistic analysis of wedge stability: distribution of the Factor of Safety and wedge geometry
Figure 1 presents the results of the probabilistic analysis of wedge stability performed using the Unwedge software. The left part of the figure shows a histogram of the Factor of Safety (FS) distribution, generated from a random sampling of the input data across the entire perimeter. The majority of realizations are concentrated in the low FS range, with a significant portion below 1.0, indicating a high risk of wedge instability under the given parameters.
Figure 2 – Spatial distribution of support pressure depending on fracture orientation
Figure 2 presents a three-dimensional diagram of the maximum required support pressure to achieve a Factor of Safety (FS) of 1.5, depending on the excavation direction and dip angle. The diagram is based on the results of a probabilistic analysis conducted in the Unwedge software and illustrates how the spatial orientation of fractures affects the required support pressure. The maximum pressure values correspond to specific combinations of wedge orientations that form the most unstable configurations relative to the excavation contour.
Figure 3 – Dependence of the maximum required support pressure on the excavation axis orientation
Figure 3 illustrates the dependence of the maximum support pressure (required to achieve a Factor of Safety, FS = 1.5) on the azimuth of the excavation axis (Tunnel Axis Trend). The graph demonstrates how the excavation orientation relative to fracture systems affects the required support pressure. It can be observed that for certain excavation axis directions (approximately 130° and 310°), the maximum pressure (up to 0.037 MPa) is required to ensure stability, which corresponds to the formation of the most unstable wedges. These results enable the optimization of excavation direction and support design to minimize the risk of collapse.

AP23487471 «Research and development of a technology for producing furnace lining from technogenic waste of steelmaking production for the metallurgical industry», Project Supervisor – Arinova S.K.
Relevance
Currently, the foundry and metallurgical industries of Kazakhstan require more than 500 thousand tons of refractory materials annually. The main factors leading to premature wear of these materials are their insufficient thermal resistance, low density, and destruction under the influence of molten metal.
To improve the thermal resistance of refractories, the use of steelmaking production waste is increasingly being applied. Kazakhstan has already accumulated 32 billion tons of industrial waste, and this volume continues to grow. A significant portion (70%) consists of technogenic-mineral formations. In the Karaganda region, 110.7 million tons of this waste are concentrated, of which only 42% is recycled, and the rest is stored on industrial sites.
Recycling and utilizing technogenic waste in metallurgy, particularly for furnace lining, can be a solution to this problem. This approach will reduce the anthropogenic impact on the environment near metallurgical enterprises, decrease resource and energy consumption of production processes, and increase environmental and economic efficiency.
Project objective: Development of the composition and production technology of furnace lining based on waste from the metallurgical industry, with increased strength and density using mineral raw materials of the Republic of Kazakhstan.
Results achieved:
Experiments were conducted to develop a pilot composition of refractory material. In accordance with the obtained mathematical model, experimental work was carried out to design the composition of pilot refractory materials. At this stage of the study, experiments were performed with the addition of slag, as well as slag in combination with ash.
Permissible limits for the use of a conglomerate (ash and slag) in the manufacture of chamotte refractory products were determined to ensure compliance with industrial requirements. The results confirm the suitability of the conglomerate for refractory production.
The use of steelmaking slag as an additive in refractory materials was investigated. Strong and homogeneous materials with low porosity were obtained, making them suitable for lining thermal units in the foundry and metallurgical industries. The conducted studies confirmed the possibility of using ash from low-grade coal as a component of the batch for producing refractory materials. The addition of coal ash to clay allows the compressive strength and density of the samples to be maintained at the level of SHA-type refractories, while reducing open porosity and decreasing the number of large pores. This effect contributes to improved slag resistance of the resulting products.
Relationships between the strength characteristics and thermal shock resistance of the investigated samples were established. Steelmaking slag was used as a modifying additive to enhance the thermal shock resistance of refractory materials.
The slag is characterized by an increased content of calcium silicate phases which, according to the analysis performed, improve the formation of the material structure under high-temperature exposure. As a result, thermal shock resistance increases without a noticeable loss of strength characteristics, making this slag a promising additive for the production of refractory products.
The obtained pilot composition of the refractory material demonstrates performance indicators that meet the established requirements of regulatory documentation. The products are characterized by acceptable values of open porosity, linear shrinkage, refractoriness, and compressive strength, confirming compliance of the pilot sample with GOST standards and its suitability for further application.

АР23487471 Development and Investigation of Exogenous Suspension Casting Technology for the Production of Alloy Castings Using Modifiers and Foundry Waste, Project Supervisor – A.Z. Isagulov.
Relevance: Modern production places high demands on the quality of cast parts. It is possible to ensure the quality of castings by forming a homogeneous dense casting structure. In turn, these indicators can be obtained by controlling the rate of solidification of the casting and the distribution of alloying elements inside it. One of the promising ways to control the casting structure is casting according to gasified models using inocultors. By using modifiers simultaneously with inoculators, the number of crystallization centers and the distribution of alloying elements can be adjusted. At the same time, it is proposed to use foundry waste (scrap, scrap) as inoculators, which will positively affect the sanitary and hygienic situation in the foundry and will make it possible to reduce the cost of casting.
Project objective: To develop and implement an exogenous suspension casting technology for the production of alloy castings using dispersed inoculants to enhance casting quality.
Results achieved:
A preliminary technological process chart for manufacturing castings by the exogenous suspension casting method using dispersed inoculators has been obtained.
It was determined that the proposed suspension casting technology with the use of dispersed inoculators is a promising method for producing shaped castings, especially thin-walled ones and those made from alloys of complex compositions. This casting method makes it possible to obtain shaped castings of complex geometry with high surface quality and a lower number of casting defects compared to the conventional method of casting into sand–clay molds. This method is sufficiently cost-effective, since foundry production waste is used as inoculators in the manufacture of models.
The influence of auxiliary elements of the polystyrene model on the mechanical and technological properties and the structure of the castings was investigated. Experimental samples with different contents of nanoparticles were obtained.
In order to identify the optimal structure and, consequently, the properties of the finished part, studies were conducted on the effect of the amount of nanoparticles on the microstructure of the finished casting.
The microstructure was examined for the presence of non-metallic inclusions, determination of grain size rating, and the presence of porosity.
The level of contamination by non-metallic inclusions is 4 points according to GOST 1778-80. The non-metallic inclusions are represented by oxides, nitrides, and carbonitrides of chromium, titanium, vanadium, and molybdenum. The contamination index was practically the same at any nanoparticle content.
Microstructural studies for porosity showed that the particle content affects its nature. The structure is characterized by lower volumetric porosity when nanoparticles are introduced in an amount of about 0.1–0.3% of the casting mass and by a finer and more uniform distribution of porosity.
When the nanoparticle content is reduced, their influence is minimized and porosity is concentrated in the surface layer. When the content is increased, axial porosity is observed.
It was determined that the higher the density of the foam plastic, the lower its porosity and the poorer its burn-out ability.

AP23485184 “Technology of Nuclear-Geophysical Testing of Coals Based on Gamma Spectrometry of Natural Radioactive Elements” Project Supervisor – Pak Y.N.
Relevance
At present, mining enterprises mainly use standard methods for coal sampling, which include the collection of primary samples, their processing (crushing, grinding, reduction), and direct thermogravimetric analysis involving the combustion of an analytical sample (~0.1 mm, 1–2 g) of coal followed by the calculation of ash content. Significant drawbacks of the traditional sampling method are its high labor intensity and low representativeness, as the quality of a large coal batch (hundreds of tons) is assessed based on the results of thermogravimetric analysis of a small analytical sample. In some cases, the final stage of sampling is replaced by instrumental nuclear-physical methods that use radioisotopic sources of gamma and neutron radiation. However, the errors caused by the heterogeneity of coals during labor-intensive stages of sampling and sample preparation remain. An innovative approach to solid fuel testing is proposed, which involves measuring the gamma radiation spectra emitted by natural radioactive elements (uranium-238, thorium-232, and potassium-40). This approach enables high-sensitivity and high-accuracy assessment of coal quality in large masses without prior sample preparation. The practical significance of the research results lies in the development of a new nuclear-geophysical technology for coal testing based on natural gamma radiation spectrometry. This technology will allow the implementation of a quality management system during coal mining and processing based on prompt and objective information about ash content.
Results Achieved in the Second Half of 2025:
As a result of the conducted research, stable correlation relationships were established between the instrumental signals of gamma spectrometric measurements and the concentrations of natural radionuclides (U-238, Th-232, K-40) in tested coals of various genesis and ash content. The analysis of spectra made it possible to identify informative energy lines that most sensitively reflect variations in radionuclide content in the studied samples. This provided an opportunity to improve the accuracy of quantitative interpretation of gamma spectrometry data when monitoring the natural radioactivity of carbonaceous raw materials.
An individual interpretational algorithm for quality assessment was developed, taking into account the ratio of measured instrumental signals as reference parameters to enhance the sensitivity and precision of testing under conditions of diverse radiogeochemical and petrophysical characteristics.

Verification of information models with real technologies of Vanyukov, ISASMELT,™ Ausmelt, ElTeniente, Salvador, Mitsubishi, QSL, Outokumpu, KIVCET was carried out. For each technological scheme of copper, lead, zinc, tin production, its own information model has been developed, taking into account the indicators of the content and recovery of the target component at each level of its hierarchical structure. Topics related to the verification and certification of software used for the development of information models are also touched upon.
The information model in production represents a new aspect in the modernization of existing and the creation of new technological schemes. The scientific novelty of the research lies in the creation of new mathematical models and software modules for the development of information models, covering all technological stages in the production of non-ferrous metals from mining to electrolytic refining in order to obtain an industrial product of the required quality.
Achievements
Used by Wolfram Mathematica to build and visualize diagrams, graphs of functions of one or more variables, networks, graphs, geographic information, interactivity, and movement in any of the classic formats.
In order to create an IM, the project developed a mathematical model of the hierarchical structure of metallurgical production, covering all technological stages in the production of non-ferrous metals. The model was verified using the coefficient of nonlinear multiple correlation, a universal criterion for a 95% level of reliability of the calculated indicators with practical indicators of the content and extraction of the target component as it moves from raw materials to an industrial product. The scientific novelty of the research lies in the creation of new mathematical models and software modules for the development of IM in the metallurgical industry, taking into account the influence of internal and external load factors. Used by Wolfram Mathematica, WinCC OA, to build and visualize diagrams, graphs of single or multiple variable functions, networks, graphs, geographic information, interactivity, and movement in any of the classic formats. In the project, diagrams, graphs of the dependence of IM and real systems of non-ferrous metal production were built on its basis, and correlation coefficients were calculated. An increase in the coefficient of correlation of IM with real schemes as they are perfected indicates its adequacy and objectivity.

Cooperation, including international cooperation
A mathematical model of the incompressible motion of the melt in a limited region was developed.
The metal melt moved along the inclined chute of the metallurgical equipment.
The motion of the melt is described by the Navier-Stokes equations 1–2:
Verification of theoretical results with practical ones made it possible to develop a mathematical model of melt motion and a numerical algorithm for integrating hydrodynamic equations, which will make it possible to predict the technological parameters of casting to obtain high-quality products.
Confirmation of the theoretical results obtained with real parameters of copper melt motion in the technological equipment of the Kazkat Copper Rod Production Plant confirmed the validity and reliability of our research. The correctness and reliability of our calculations were confirmed using real temperatures of the copper melt movement in the range of 1425-1555 [K], which is close to the temperatures in industrial conditions. Calculations show that the average value of the contour velocity is approximately equal to the average velocity of copper melt at the Kazkat copper rod production plant. The results show that the best melting occurred at 1555 [K].

Relevance
Currently, industrial enterprises operate in a market economy, one of the main features of which is competition. Thus, in modern economic conditions, improving the efficiency of the production process by optimizing its technological parameters is one of the priority tasks of an industrial enterprise.
The optimization of the technological process is based on a detailed model of the product manufacturing process, which describes changes in its state in the form of a set of parameters. Based on the digital model, target indicators are optimized by varying the values of control parameters within specified ranges.
From a control process perspective, the technological process of mechanical processing is a structurally complex control object and represents a clear sequence of intermediate states of the product in the process of changing the structure and properties of the initial blank. The result of controlling this process is a set of optimal values of technological parameters that contribute to achieving intermediate states of the product that meet the specified requirements.
In this case, the task boils down to forming the best-optimal-control strategy within a multi-level hierarchical system. The overall target state of the control object is characterized by a balanced system of target indicators that determine the overall effectiveness of the system.
The implementation of this project is aimed at fulfilling the main objectives of improving the efficiency of BigData management at machine-building enterprises based on the development of a digital model of the production process (digital twin), which allows, already at the stage of technological preparation of production, to determine the optimal values of the technological parameters of the product manufacturing process, aimed at reducing labor intensity and cost, as well as improving its quality by modeling various product manufacturing scenarios.
The relevance of the research topic lies in the digitalization of production processes at machine-building enterprises, based on the development of a structurally complex hierarchical model of the product manufacturing process, which allows optimizing the technological parameters of the production process depending on the selected optimization strategy, taking into account resource constraints.
Project objective
