P.; Sokur, M. I.; Biletskyi, V. S.Purpose. Determining the rational operating parameters for granite crushing under impact in the field of centrifugal forces to obtain cubiform crushed stone. In order to achieve the purpose set, the task is to determine the operating parameters for obtaining the main grain-size classes: -50.0 + 20.0; -40.0 + 20.0; -20.0 + 10.0; -10.0 + 5.0 and 5.0 mm. Methods. The crushing process of granite crushed stone is studied in the conditions of the Kolomoievskyi Granite Quarry, Dnipropetrovsk region. Granite crushed stone with an initial grain-size of 100.0-0.0 mm and strength grade of M1400 is subjected to crushing. The accelerating rotor rotation frequency is the design value n = 200-1200 min⁻¹. Fine crushing of granite is performed in a centrifugal-impact crusher by a free impact in the field of centrifugal forces. Findings. The optimal speed modes of centrifugal crusher operation, which provide the production of high-quality crushed stone with a maximum content of 90-95% cubiform fractions, have been substantiated. Originality. The yield dependences have been obtained of the grain-size classes: -50.0 + 20.0; -40.0 + 20.0; -20.0 + 10.0; -10.0 + 5.0 and 5.0 mm depending on the speed mode of the centrifugal crusher operation. Practical implications. The operating parameters for obtaining the main grain-size classes of cubiform crushed stone from granite have been determined: -50.0 + 20.0; -40.0 + 20.0; -20.0 + 10.0; -10.0 + 5.0 and 5.0 mm. In particular, it has been determined that for the production of cubiform crushed stone with -50.0 + 20.0 mm grain-size, the rotor rotation reasonable speed is 400-500 min⁻¹ (the speed of material departure from the accelerating rotor is 45-50 m/sec); for cubiform crushed stone of -40.0 + 20.0 mm grain-size, the speed mode is 200 min⁻¹ (25 m/sec); for cubiform crushed stone of -20.0 + 10.0 mm grain-size – 600-650 min⁻¹ (70-80 m/sec), respectively. The maximum content of cubiform fractions in the -20.0 + 10.0 mm grain-size class is 95%, which is achieved at a rotor speed of 650-700 min⁻¹ (departure speed is 75-80 m/sec). The maximum content of cubiform fractions in the -10.0 mm grain-size class is 94-95%, which is achieved at the accelerating rotor speed within 700-800 min⁻¹ (departure speed is 70-80 m/sec). The obtained data make it possible to practically choose a rational speed mode of the centri-fugal-impact crusher operation to obtain the maximum yield of cubiform crushed stone.Документ Optimization Principles Implementation in the Innovative Technologies for Re-used Extraction Workings Maintenance(2022) Bondarenko, V. I.; Kovalevska, I. A.; Biletskyi, V. S.; Desna, N. A.This paper studies the main approaches to optimization principles implementation in innovative technologies for reused mine workings. Based on the experimental data processing and using the correlation analysis methods, the possibility of achieving the correspondence of the deformation-strength characteristics of the fastening structures to the optimal values of loads and displacement, at which the intensity of rock pressure manifestations is minimal, has been proved. A series of multivariate computational experiments with various mining-and-geological and mining-engineering factors have been conducted to determine the characteristics of the fastening structures in the conditions of the Western Donbass coal mines (Ukraine). Based on the comparative analysis of the experiment and analytical calculations, it is possible to represent recommendations for the use of the combined roof-bolting systems in difficult mining-and-geological conditions when maintaining reused extraction coal-mine workings.Документ Specifying the Methods to Calculate Thermal Efficiency of a Dual Production Well System "Fluid-Geoheat"(2022) Fyk, M. I.; Biletskyi, V. S.; Abbood, M.; Desna, N. A.Methods to calculate thermal efficiency of dual production well system “fluid-geoheat” have been specified for conditionally thin productive fluid-saturated seam in terms of radial planar filtration. It has been demonstrated that relative to a variant, ignoring Joule-Thompson effect, and variant of discrete Joule–Thomson coefficient substitution, calculation accuracy as for the well heat efficiency increases by 33% and 9% respectively. It has been proved that it is expedient for a conditionally thin seam to use effective temperature within the heat-exchange equitation with Fourier substitution as related to heat transfer while considering heat input in terms of unidirectional input to a virtual disk plate from the seam floor. In the context of the proposed calculation methods, increase in numerical estimations of thermal efficiency of a well results from the consideration of extra heat pumping owing to Joule-Thompson effect by rocks adjoining the productive formation.Документ Comparative analysis of Facebook informational and educational pages statistics(Publishing House "Universal", 2022) Adamia, Zoia K.; Onkovуch, Ganna V.; Biletskyi, V.

I.; Biletskyi, V. S.This paper relates to mining-well technologies. A theoretical and methodological approach is proposed to modeling geothermal well systems, which includes the development of: principal technological scheme of a geothermal system; schemes of transformation and movement of energy and a heat-transfer medium; the geothermal system phenomenological model; analysis of subprocesses and obtaining their mathematical models and, on this basis, the mathematical model of the geothermal model as a whole. An example of an advanced open-type geothermal well system is studied, which is based on the oil-and-gas well with one loop of circulation and the parallel connection of heat pumps at characteristic points of the system. The subprocesses of the developed phenomenological model are analysed and the characteristic features of their mathematical description are revealed; in particular, it is substantiated that the redistribution of heat power entering from a fluidsaturated bed is substantially dependent on the lateral wellbore geometry. Another important feature is to model the downhole heat pump and the modes in the scheme as a whole, which is based on the mass flow rate of a heat-transfer medium in its circulation loop. A generalized formula is presented for the heat power of the analysed advanced geothermal well system.Документ Improving the geometric topology of geothermal heat exchangers in oil bore-holes(2019) Fyk, M. I.; Biletskyi, V. S.; Ryshchenko, Ihor; Abbood, MohammedA review has been conducted of key trends in the development of geometric topology of geothermal heat exchangers. Authors proposed approaches to improving the designs and network structures for heattransfer media circulation in the bottom-hole space of oil-and-gas reservoirs. Four geometric topologies of geothermal heat exchangers have been analysed: І – ІІ – rectilinear vertical smooth and finned pipelines; ІІІ – IV – a cluster in the form of a set of smooth and finned single-pipe elements, representing a figure of "squirrel wheel" or "meridian sphere" type. It is shown that the most effective technical solution, which ensures the increase in the coefficient of performance (COP) of bore-hole geothermal systems is finning the heat exchanging pipes. For the heat exchangers of І – ІІ type, the calculated increase in COP in comparison with smooth pipes is 40%, and for ІІІ – IV type – 95%. The key parameters influencing the COP of a geothermal heat exchanger are: the radius of fluids draining out during the heat exchange process, the radius of pipelines with circulating heat-transfer medium, the diameter of a cluster heat exchanger, the heat exchange area, the parameters of rocks thermal resistance in the bottom-hole zone of heat-receiving.Документ Resource evaluation of geothermal power plant under the conditions of carboniferous deposits usage in the Dnipro-Donetsk depression(2018) Fyk, M. I.; Biletskyi, V. S.; Abbud, M.The objective of the work is to substantiate the actualization of the problem of obtaining geothermal energy from oil and gas wells of oil and gas production facilities in the central-eastern part of the Dnieper-Donetsk Depression (DDD). The research methodology is based on the collection and statistical processing geophysical data of the DDD oil and gas deposits, the use of balance equations for energy and substance matter. The main result of the work is that the principal technological scheme of the geothermal system has been developed and the geothermal potential of oil and gas wells in the experimental zone has been analyzed. There have been considered the technological and ecological aspects of geothermal heat usage from depleted deposits of the DDD wells, which were disclosed into сarboniferous deposits productive horizons.Документ Improved thermogasodynamic model of a geothermal gas condensative deposit with production well(2019) Fyk, M. I.; Biletskyi, V. S.; Al-sultan, M. B.; Abbood, M. H.It is shown in the work that the wells-fluid are extracted from rocks by heat-retaining fluid from the open geothermal reservoir as from object with distributed cross-sectional parameters. This is due to the fact that the actual temperature distribution of the geothermal reservoir in dynamics affects the thermal properties of fluid-retaining rocks, which in turn affect the coefficient of heat exchange and heat transfer along the cross-section between the moving fluid, the fluid-retaining layer and adjacent rocks. The static temperature field of the original geothermal gradients in the case of outflow injection of the circulating coolant changes from the sides of the reservoir to the wellbore. A model of geothermal reservoir of gas-condensate well has been developed, which takes into account changes of thermal conductivity of rocks from the reservoir counture to the well bottom. The model includes refined equations of thermal energy balance for radial filtration of well production, containing convective and conductive components of heat exchange and heat flow. This allows, in comparison with the known methodological approaches, to clarify by 12-14% the forecast of heat extraction from a geothermal reservoir with a circulating coolant thrue the bottom and productive layer of a gas-condensate well.
