Authors: Kostenko G P , Zgurovets O V , Tovstenko M M 
Published: November 2023

Abstract
An analysis was carried out to examine the prospects for the integration of smart charging technologies, such as Vehicle-to-Grid (V2G), into the power system in Ukraine. The country is experiencing a growing concern regarding greenhouse gas emissions. The transport sector in Ukraine is one of the most energy-intensive sectors of the economy and contributes significantly to environmental degradation. The use of internal combustion engines in transport also increases the country’s dependence on imported fuel due to the high demand for petroleum products. The integration of electric transport and smart charging technologies, particularly V2G, is seen as a critical solution with immense potential to mitigate climate change. V2G technology is becoming increasingly relevant as the world transitions towards a more sustainable energy future. V2G refers to the bi-directional flow of energy between electric vehicles (EVs) and the grid. With V2G, EVs can not only consume energy from the grid but also supply energy back to the grid during peak demand periods, helping to stabilize the grid and increase its resilience. Therefore, it is imperative to develop a stable policy to promote these technologies and compare the features of the policy of integrating electric vehicles and the energy system in Ukraine. A qualitative strategic planning methodology, Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis, was used to evaluate the diverse measures and initiatives related to electric transport development and infrastructure while integrating them into the power system. This analysis identified problems associated with the impact of EV charging on the power system, such as the inability to provide increased energy needs or limiting the EV charging infrastructure load. However, a high percentage of renewable energy sources, increased social awareness of climate change, and reduced prices of electric vehicles could provide the necessary opportunities for developing electric transport in Ukraine.

Abstract
In the paper showing that one of the main way for Ukraine electric power industry evolution is electric power networks and systems improvement and construction considering Smart Grid concept. The main idea of Smart grid is the reliable, energy-efficient and high-quality energy supply system. To implement the idea, it is necessary to create a high-performance information and computing infrastructure. The main components of Smart Grid is emergency mode diagnostics and damage monitoring. Providing fault diagnostics and fault monitoring can improve the power supply reliability and quality to consumers. So, the task of quickly and accurately determining the place of damage is important. In the article showing that emergency detection tools in sections of both cable and overhead electrical networks it’s a way to improve efficiency of the networks. The diagram of the placement of damage indicators on the section of the electrical distribution network is presented, which allows determining the direction of the search for the location of the damage. A comparative analysis of measuring current transformers of optical and electromagnetic type was carried out. It is shown that a significant number of advantages of optical measuring current transformers, which can be used in damage indicators, can be provided by measuring current transformers of the electromagnetic type. Creating fault indicator based on the Smart Grid concept lets do to reduce searching time for the cause and location of an emergency situation to a minimum. In this concept application fault indicator in energy grid ensure it connection to operating overhead and cable lines without removing voltage by connecting the output of the secondary winding of the measuring current transformer of the detachable design to the measuring converters directly placed near the current measuring transformers with the help of a mechanical spring fastener. A block diagram of a specialized information-measuring system with a damage indicator was created, taking into account the requirements of the Smart Grid concept, which allows to reduce the time of searching for the cause to a minimum.
Assessment and improvement of digital resilience in the energy crisis caused by missile strikes
Authors: Zubok V 
Published: November 2023

Abstract
The relentless penetration of information and communication systems into all spheres of life and the widespread use of digital technologies has been called “digital transformation”. Different systems demonstrate a different ability to effectively resist risks of any origin and nature, adapt to changes in the environment, maintain rapid recovery and return to maximally stable functioning. Such properties are generally called resilience. If these properties are acquired or enhanced through the use, application and development of digital technologies, we call them digital resilience. To analyze digital resilience, it is suggested to consider digital subscribers, digital needs, digital tools and their dependencies. Practical examples of such dependencies are given, which are formed under the influence of systematic missile attacks of the aggressor on the power energy system of Ukraine. The foundation was laid for a combined digital resilience assessment methodology that includes a metric approach and the theory of topological spaces.

Abstract
The article studied the issue of improving the scientific and methodological base in the field of design and planning of open-pit mining by developing new and adjusting existing methods for determining the ore productivity of an open-pit, which should take into account the interconnection between the mining schedule and the productivity of an open-pit for ore, based on the condition for ensuring the standard volume of finished to the extraction of reserves. When choosing the production of an open-pit for ore, it is necessary to take into account the impact of the interconnection between the schedule of mining and production, based on the conditions of regulatory regulation of the volume of mining for the excavation of reserves, on the cost of ore mining and concentrate production. With an increase in ore productivity, the cost of ore mining, as well as the cost of production of concentrate reduction. At the same time, the very possible productivity of the open-pit for especially minerals is achieved, the economic efficiency of the development of deposits is achieved with the chosen direction of the open-pit. A decrease in productivity for a common mineral by 20 and 40% entails a decrease in profit from the development of the deposit by 10 and 20%, respectively. It has been determined that an increase in the slope angle of the working side of the open-pit significantly reduces the economic efficiency of the development of the deposit due to the fact that the operation of the open -pit with a large slope angle entails not only a decrease in the current stripping ratios as a result of an improvement in the mining schedule, but also a decrease in ore productivity, which reduces the present value of marketable products due to an increase in the period of development of the deposit. The results of the studies performed can be used by design organizations and mining enterprises in determining the ore productivity of an open-pit.

Abstract
This paper studies the ways of solving the resource-saving direction of the strategy for the mining industry development in Ukraine. The existing ideas about the patterns of changing stress-strain state (SSS) in the mass during the stope mining of minerals are analyzed. The problem of the host rock SSS formation and development is studied. The main directions of studying the relationship between the parameters of mass SSS anomalies in the area of stope operations and their technological parameters has been substantiated with the selection of a methodology for conducting multivariate computational experiments. A macromodel has been constructed to calculate the change in the distribution fields of the rock mass SSS components with subsequent substantiation of its idealizations. The principles of matching the macromodel and the subordinate models have been studied. A new methodical approach is proposed for taking into account the time technological parameters (average daily face advance velocity and the duration of its stoppage) through their relationship with the mechanical characteristics of the rocks. A test assessment of the adequacy of the performed calculations based on the spatial model SSS analysis for all stress components has been conducted. The degree of influence of the stope face advance velocity and the mass texture on the parameters of rock pressure anomalies has been studied, as well as the linking patterns in the area of conducting stope operations have been obtained: frontal and lateral bearing pressure zones and a zone of destressing behind the stope face. A base has been created for studying and predicting the rock pressure manifestations in critical areas in order to develop recommendations for choosing rational technological and design parameters for high-rate mining of coal seams.
Identification of resistance torque on the roller cone bit in the drill rod rotation drive
Authors: Khilov V S 
Published: November 2023

Abstract
There is a problem of increasing the durability of the roller cone bit of the drilling rigs used in the quarries of Ukraine. One of the effective ways to solve it is to apply the control method of maintaining a constant flow of mechanical power in the bottom hole zone. The implementation of such a control method leads to the necessity of controlling and limiting the resistance torque on the roller cone bit. To solve the problem of determining the resistance torque, we used methods of parameter identification: the Luenberger observation device with adaptation to external influences; estimation of the resistance torque using an extended observation object; the theory of regulators adapting to perturbations. It has been established that the most rational method of identifying the resistance torque on a roller cone bit is an astatic monitoring device, which allows to implement a method of controlling the rotation of the drill rod by a drive mechanism that maintains a constant flow of mechanical energy through the roller cone bit and increases the durability of the roller cone bit.

Abstract
In Kryvyi Rih iron ore basin, long-term and intensive mining of deposits applying open pit methods have resulted in significant areas disturbed by open pits, dumps and tailings storage facilities. Hundreds of thousands of hectares of fertile arable land are already unsuitable for agriculture and sometimes for living. Thousands of tonnes of dust from dumps and tailing ponds deteriorate the surrounding nature every year and pollute the atmosphere in mining basins. Industrial ore breaking in open pits using bulk blasting causes emissions of a significant amount of harmful dust and carcinogenic substances. The environmental situation in open pit mining areas is often close to critical. In addition, bulk blasting forms a seismic wave, which in some cases destruct civil buildings and industrial facilities. The article proposes ways of gradual transition from mining mineral deposits by open pit methods to environmentally friendly technologies of open pit-underground and underground mining. It is established that such transition is a forced and at the same time choiceless way of developing mining areas, in particular Kryvyi Rih iron ore basin. The paper notes that the main problems of this transition include geomechanical stabilization of the rock massif during construction of underground mines in areas of possible impacts of open pit fields. The paper develops the fundamental study of the problems of controlling the stress-strain state of the massif during transition from the open pit to combined technology of deposit mining. Technologies of combined mining that involve formation of a transition belt with backfilling the worked-out space with compound mixtures are studied as well. It is proved that development of theoretical foundations for controlling the stress-strain state of the massif during transition from the open-pit to combined technology of deposit mining, study and design of technological solutions that contribute to transition to open pit-underground and underground mining, is an urgent scientific, technical and practical problem of great importance.

Authors: Harkava O V , Pavlikov A M 
Published: November 2023

Abstract
Based on the design assumptions according to Eurocode 2, the concept of determining the value of the design strength of reinforced concrete has been developed for calculating the bearing capacity of reinforced concrete members subjected to biaxial bending. The theorem on the parallelism of the planes of internal and external forces action is applied. The considered design cases are for the most expected forms of the compressed concrete areas, which are characteristic for biaxial bending of beam members. The value of the coefficient of influence of biaxial bending on the characteristics of the member of rectangular section with triangular and trapezoidal forms of the compressed concrete area is obtained. A methodology for calculating the bearing capacity of biaxially bended members based on the application of the design strength of reinforced concrete is brought to the engineering level of application. An example of a calculation is presented, which demonstrates the convenience and effectiveness of the developed method. The proposed method of calculating the bearing capacity of beam member under biaxial bending is approved by comparing the results of calculations with experimental data for 12 samples of biaxially bended beams.

Abstract
A research of the causes and consequences of bulking of activated sludge was conducted at existing biological wastewater treatment plants (municipal and local at an industrial enterprise). The filamentous bacterium that was caused the bulking of the activated sludge in the studied treatment plants was identified as Type 021N. It was established that the studied filamentous bulking causes a significant deterioration of the technological characteristics of activated sludge flocs and it is accompanied by suppression of the nitrification process. To suppress the bulking of activated sludge two methods of suppressing the inflow of hydrogen sulfide into biological treatment plants were successfully used: blowing from wastewater at municipal treatment plants and inhibiting its formation at local treatment plants in the settling and laminar flow zones.

Abstract
Biomass gasification is one of the effective methods of obtaining electrical and thermal energy. Thermal gasification is a simple and effective method for most lignocellulosic waste. The generation of combustible gases under such conditions has significant prospects both in the national economy and in a number of chemical-technological processes. The high-ash carbon residue remaining after thermolysis has shown its effectiveness as one of the important components of organo-mineral fertilizers. The results of field research in 2018-2019 with Moskito corn hybrid (Zea mays L.) and Mulan winter wheat F2 hybrid (Triticum aestivum L.) on dark-gray podzolic soil confirmed the high agrochemical efficiency of our proposed fertilizers. The introduction of Moskito corn hybrid organo-mineral fertilizer into the nutrition system improved the structural indicators of the harvest: in the experiment, the 1000 grains weight increased by 14.7%, the mass of grain from one cob – by 20% compared to the control. Balanced nutrition of experimental plants Mulan winter wheat F2 hybrid in the variant with the use of BG-II when sowing at a dose of 1t/ha and favourable weather conditions led to an increase in grain quality (protein content) to the 2nd class – 13.0% against the 3rd grade in control (12.2%).
Environmental safety of soil genetic horizons in the impact zone of Lviv city landfill (Ukraine)
Authors: Popovych V V 
Published: November 2023

Abstract
Landfills cause significant technogenic pressure on the environment, being the center of depositing large volumes of hazardous materials in a relatively small area. Interacting with each other they form hazardous substances and compounds. In this study, we describe three genetic soil horizons that are within the impact zone of the landfill of a city of millions of people. It was established that the distribution of mobile forms of heavy metals according to the profile of the studied soils tended to gradual decrease with depth. When describing the genetic horizons of three profiles located in the impact zone of the landfill, it was established that the content of heavy metals in them does not exceed the MPC, except for Pb. The soil at the foot of the landfill turned out to be the most contaminated with heavy metals (profile No. 3). The activity of micromycetes in this soil was the lowest here. In general, all soils in the impact area of the landfill are impoverished in micromycete distribution. The taxonomic composition of mycelial fungi and the identified species’ ecological and biological characteristics indicate significant ecosystem pollution by household waste.

Abstract
The triune concept of sustainable development takes into account environmental, social and economic issues in general. At the same time, the solution of the problems of resource conservation and socio-economic development do not contradict each other, but contribute to mutual reinforcement. The purpose of this study is to build, describe, test and analyze economic and mathematical models of the processes of self-organization of the socio-economic system within the framework of the concept of sustainable development. The considered models take into account both quantitative and qualitative characteristics. The research methodology is based on the assumption that the system under consideration is dynamic. The study makes it possible to evaluate the process of sustainable development of the socio-economic system in terms of the formation and influence of its characteristics on the overall result. Various options for formalizing the level of motivation of economic activity are described and analyzed, one of which is based on the economic interpretation of the Weber-Fechner psychophysiological law. The assumption of the continuous development of innovative technologies made it possible to reveal the existence of a “fatigue point”, the onset of which indicates the possibility of increasing the growth rate of production activities due to its technological transformation.
