Published: November 2023

The article considers synthesis of an expert system for controlling electric power consumption by pumps of main water drainage facilities of an underground mine on the basis of the Mamdani fuzzy inference algorithm. The proposed system has a MISO-structure (multiple-input, single-output) with two input variables, such as water inflow and power cost as well as one output coordinate – power of pumping units. Two bases of fuzzy rules such as conjunction (AND) and disjunction (OR) are formed. By simulation modelling, a comparative analysis of fuzzy control systems for power consumption by water drainage facilities is carried out, as well as a system without control, when the pump performance is stabilized, during week and month periods. It is established that OR-rule based systems can reduce power costs by 1.89% during a week and by 2.28% during a month, and AND-rule based systems by 4.13%, as well as by 5.43% during week and month, respectively. At the same time, we note that the economic effect is achieved not through a decrease in power consumption, but by adjusting the operation mode of the water drainage facility, which involves ensuring maximum efficiency of groundwater drainage when the power cost is high, and minimum efficiency when it is low.

In the Republic of Kazakhstan, there is a noticeable shortage of water resources, which is a consequence of the natural features of its territory and climate. In particular, there are big problems in the water supply to the Mangystau region. The main source of water in the region is the Samskoye groundwater field. In this work, the conditions of the Samskoye field are typified, the method and technological parameters for drilling a typical well are selected and substantiated. It has been established that rotary drilling with reverse circulation in the conditions of the Samskoye field has significant advantages. The maximum possible production rate of drilling with reverse circulation, taking into account the limited thickness of the aquifer, is 4.3 times higher than with rotary drilling with direct circulation and 2.5 times higher than with percussion drilling. With the same filter pipe diameter, the greatest possible thickness of the gravel pack layer in reverse circulation drilling is 15 times greater than for conventional rotary drilling and 3.7 times greater than for percussion drilling. Thus, the use of rotary drilling with reverse circulation will solve an important problem – the provision of domestic and drinking water supply to the area.

Dnipro University of Technology is a leading institution where an authoritative scientific school was formed to solve the fundamental issues of percussive-rotary drilling with the help of hydraulic hammers. This method makes it possible to intensify significantly the mining processes of rock mass breaking. In order to perform the specified function as fully as possible, hydraulic hammers are to work in a certain technological mode and have appropriate technical characteristics; the paper deals immediately with the analysis of those characteristics. The original designs of hydraulic hammers proposed by the authors are distinguished by a high degree of reliability of the interaction of individual parts and assemblies. Simulation of the operation of hydraulic hammers under appropriate mode-parametric support revealed a number of their significant advantages, i.e. in terms of creating effective conditions for rock mass disintegration. It has been proven convincingly that some features of the approaches to the implementation of a hydraulic well washing programme correspond to the stability of a high-quality process of the downhole work of percussion machines. As a result of the research, a composition of some rational formulations of flushing fluids, which contribute to a significant acceleration of the development of destructive processes, was clarified.

Published: November 2023

Modern industrial production is aimed at the development of waste-free technological processes, wider use in the production of waste and by-products. The largest amount of waste is generated from the activities of mining and metallurgical enterprises. One of the problems of foundry production is the disposal of multiton solid waste, about 90% of which is spent molding mixture. Part of the spent mixture is reused as recyclable, but the main mass of it is collected at municipal solid waste landfills. This work is devoted to the study of the component composition of foundry production waste – spent molding mixture with the aim of its reuse. According to the results of the research carried out by the authors, mineralogical recommendations regarding its reuse were provided. Involvement in the reuse of spent molding mixture will allow to free up part of the solid household waste landfills, reduce the negative man-made load on the environment, and additionally obtain conditioned restored molding sands.

Published: November 2023

Conical monolithic thin-walled reinforced concrete blocks (shells) can be used as foundations for frame structures and buildings with load-bearing walls. As an analogue of columnar foundations, this type has the advantage of the speed of installation. It almost wholly excludes earthwork and formwork from the technological process, provided that the physical and mechanical properties of the soil base are improved. Shells are immersed in the supporting soil base with the help of dynamic or static loading. Additional soil base compaction occurs due to interaction with the conical outer surface of the shells. The work aims to develop the theoretical foundations for modelling, mathematical description and the possibility of optimizing the process of sinking monolithic thin-walled spatial reinforced concrete shells that model foundations for low-rise technological or residential facilities. Based on the analysis of the ”hammer-head-shell-soil” system, an elastic-viscous-plastic model with an attached soil mass was developed and presented, which is used as a basis for developing a system of nonlinear differential equations of the second order. The article provides recommendations on the impact of structural and technological factors on the failure rate and the contact stresses in the hammer-shell zone. The following factors have a significant influence on the failure of the shell: the height of the hammer lift, soil resistance, and the ratio of the masses of the hammer and the shell. The effect of shock-absorbing elements is insignificant. The greatest influence on the magnitude of the contact forces in the zone of the hammer-shell has: the height of the fall of the hammer and the stiffness of the resilient gasket.

The optimal shape of splitting block from massif depends on the specific plane of splitting is determined. The possible directions of borehole deviation from ideal ones, their extension due to drilling and tensions in the boreholes are studied. The introduction of the borehole’s overlapping coefficient, which influences the weakening of the massif along the directed (designed) split line, is proposed to define further necessary tensions for mechanical ways of separating blocks. The equations for determining drilling operations parameters at granite blocks splitting from dimension stone quarries massifs are proposed. The coefficient of limit values of deviation angles is defined.

Mining waste can generate environment pollution including acid mine drainage (AMD). AMD is dangerous for its surroundings and can pollute surface and groundwater it is contacting with. Nanomaterials are advanced materials used in all fields of human activity and development. However, their production is still expensive and may pollute the environment due to the chemicals’ used and/or production of the energy needed for their synthesis. A smart solution could be use of mining waste and AMD to produce nanomaterials with properties similar to the properties of nanomaterials obtained from clean chemicals. Thus both waste will be valorised / decontaminated and useful and needed materials produced. This paper presents production of nanoparticles and nanomaterials from mining waste and AMD with emphasis on iron- and copper-based materials, as well as some applications of the obtained materials.

Published: November 2023

In mining iron ore, over 60% of underground mines at Kryvyi Rih iron ore basin apply a system with the bulk caving of ore and overlying rocks. However, when the deposit dip is 45-60 degrees, application of this mining system leads to losses of about 30-40% of the footwall ore. Available methods of the loss reduction result in an increase in production costs or a decrease in the iron content in the mined ore mass. After analyzing the mechanism of forming the figure of drawing, it is proposed to change its parameters without significant costs due to the use of an inclined plane and an overcompacted ore layer. The presented study enables stating that with an increase in the inclined plane angle from 45 to 75 degrees the draw crater radius increases from 2 to 7.5 m, and a decrease in the factor of first loosening of ore leads to an increase in the radius of the crater to 10 m. Thus, for the first time it is proved that a decrease in the first loosening factor leads to the increased semi-minor axis of the ellipsoid of drawing and the width of the active drawing area, which will reduce losses of caved ore when drawing it from the stoping block in the footwall area. It is established that in order to minimize losses and dilution of ore when using level mining systems, the drawpoint should be located in the block sill at a distance ensuring formation of the 20 to 25 m high ellipsoid of drawing. In case of an overcompacted 22 m thick ore layer, it is possible to significantly reduce ore losses from 14 to 10% and ore dilution from 16 to 9%, thereby enhancing ore mass extraction indices without additional costs.

Published: November 2023

The paper describes topical issues of a prospective method for coalmine methane utilization for obtaining an additional valuable energy resource for the regional development of coal-mining areas. It is noted that the development of the extraction of methane resources is very urgent and is of great economic importance for ensuring the energy independence of Ukraine. The experience and technologies of using methane and coalmine gas by global coal-mining companies are analyzed. Modern prospects and opportunities for using coal gas are studied. There is a need to transform the coalmine methane removal system and directions for maximizing the use of its resources in a wide range of concentrations in the composition of gas-air mixtures based on the development of innovative technologies to improve the efficiency and cost-effectiveness of functioning coal-mining enterprises. Attention is focused on the advantages of using gas hydrate technologies for obtaining additional energy resource under conditions of changing coalmine methane concentrations. The specifics of the process of mixed gas hydrate formation from gas mixtures of various geneses have been studied. It has been revealed that it is the coalmine gas-methane composition that determines and forms the basic condition for hydrate formation. The thermobaric conditions for the hydrate formation process at different methane concentrations in gas mixtures of degassing systems have been experimentally determined. The results obtained are the basis for further research on efficiency of creating gas hydrates from coalmine methane and determining its minimum permissible concentration in the gas mixture of degassing systems according to the technological and economic criteria of hydrate formation.

Published: November 2023

The aim of the research is the analysis and modeling of the process of sedimentation of the solid phase of the pulp in the technological units of processing plants to assess the density of particles of crushed ore. The paper analyzes domestic and foreign experience; methods of mathematical modeling were used, as well as methods of mathematical statistics and probability theory for processing the results of experiments. Scientific novelty consists in developing and substantiating a method for estimating the density of crushed ore particles in the process of their sedimentation directly in the process units of beneficiation plants. Practical value consists in developing a methodology for determining the characteristics of the enriched raw materials, which make it possible to form the degree of grinding necessary for the full disclosure of mineral formations. It was proposed to use the density of ore particles as an indicator of changes in the quality characteristics of the ore received for beneficiation, which is determined on the basis of measurements of the attenuation of volumetric ultrasonic waves and Lamb waves propagating in the pulp and the wall of the technological sump that is in contact with it. These measurements must be synchronized with the results of measurements of the pulp level in the sump during its working operation. The proposed method makes it possible to dynamically correct the parameters of the model of a closed ore grinding cycle, depending on the quality characteristics of the feedstock, and thereby form the conditions for the full disclosure of inclusions of the useful component in the product entering the magnetic separation or flotation.

Published: November 2023

The groundwater is less susceptible to anthropogenic influence and the water quality of these sources is more stable. At the same time, the groundwater often has an increasing iron concentration. Despite the sufficient availability of proven methods for iron removal from water, it becomes necessary to search for more resource and energy saving technologies which is due to the constant rise in the cost of resources for the construction and operation of water treatment plants. The aeration methods for the iron removal from groundwater are often used, as cheaper ones. The polystyrene foam filters with upflow filtration are of particular interest, as the most reliable in operation among the developed types of filters with floating medium. A further reduction the cost of water is possible by using granules of foam polystyrene obtained by a production method, which ensures an increased grain size in comparison with the traditional method of their obtaining. The positive experience in such filters implementation allowed to recommend the placement of iron removal equipment in the existing water towers.

The article concerns of the comparative study of traditional settlements historic experience of “non-detached” preservation. “Non-detached” there is understood like a way to preserve the whole settlement on its original place, with its local traditions, community system, crafts and customs, and in the harmony with natural environment. The cases of the study are mountain Shirakawa village Ogimachi in Japan and Kryvorivnia village in Ukraine. The both settlements are generally showing very similar historical background of geographically isolated life in the harmony with high mountain nature that leads to the shaping of original local architecture style, cultural traditions and community features. Similarly, the initiative of revitalization in the both cases emitting from local communities. Nevertheless, the history of preservation and revitalization efforts of the two cases is quite different. While in Shirakawa village Ogimachi local community took revitalization efforts starting from the middle of 20th century, Kryvorivnia village was engaged in the process starting from the middle of 19th century just with some interruption due to the soviet times. Currently the both settlements achieved good results in their revitalization and local traditions preservation activity also keeping harmony with environment. Shirakawa village Ogimachi is mostly orientated on inner community life that is almost not intersected with flourishing local tourism. Contrary, Kryvorivnia allows tourists to participate freely in local community life, rituals and festivals. Thus each of the two cases examined finally found its original way of historical settlement culture sustainable preservation and revitalization.

European grayling is a perspective object of a recreational fishing. In addition, the presence of this species in sufficient quantities in rivers has a positive influence on the formation of the recreational attractiveness of mountain regions, where tourism is one of the main sources of local communities existence. However, grayling stocks in the watercourses of Ukraine are significantly depleted nowadays, and populations are in a condition of lack, what has led to the inclusion of this species into the Red Book of Ukraine. Working out of biotechnologies of artificial reproduction of rare fish species in aquaculture conditions for the further reintroduction of the resulting offspring into natural water bodies takes an important place in the system of environmental protection measures to preserve biodiversity. After all, the reintroduction into nature of artificially obtained fish fry is one of the effective ways to restore the optimal number and structure of rare fish species natural populations, and this, in turn, will allow in the future to restore the limited exploitation of the stock of these fish species. One of the critical artificial fish reproduction technology links is the transfer of larvae to external nutrition. Namely on this stage the highest mortality rates are observed. The usage of live feeds as a starter fodder can significantly improve the situation. Forage organisms, in addition to having high nutritional value, can serve as delivering tools of various targeted products, including probiotics, to a fish larvae organism. The assessment of the usage of probiotic strainLactobacillus caseiIMV B-7280 feasibility is carried, and also the possibility of usage the cultureDaphnia magnaStraus, 1820 grown in the presence of trehalose lipids, within the technology of early feeding of the European graylingThymallus thymallus(Linnaeus, 1758). It was shown that the larvae of the European grayling, which received investigated probiotic microorganisms strain, had 15% bigger weight on the final stages of feeding than the larvae of the control group. Introduction to the diet of grown-up grayling larvae of the cultureDaphnia magna, previously received of common cultivation with microalgaeDesmodesmus armatus(Chodat) E.H.Hegewald 2000 with addition of trehalose lipids, contributed to the reduction of larval mortality and the acceleration of their growth rate. Further improvement of proposed approaches of growing grayling fish planting material can be extrapolated to other fish species and in the future may be applicable in the process of growing rare fish species in conditions of farm aquaculture fish farms, what will allow them to be involved into environmental protection activities by placing appropriate orders. This, in its turn, will contribute to the stable development of communities in rural areas.

Published: November 2023

The existing problems of energy, water, and food crises and climate changes determine the need to implement appropriate adaptive measures to improve the ecological and reclamation state of drained mineral soils. For the application of deep loosening of the soil as an adaptive agromelioration measure, a transition from traditional crack loosening of the soil and strip loosening of the soil to improved technologies of continuous layer-by-layer loosening of the soil based on energy-efficient and moisture-regulating principles is proposed. Their comparative evaluation according to the main indicators of overall efficiency was carried out on drained mineral soils of a representative object in the Western Polissia zone of Ukraine. According to the results of the evaluation of various technologies of deep soil loosening, it was determined that the technologies and technical means of continuous deep loosening of the soil have an advantage in all main indicators: agrotechnical, water-physical, energy, technological, ecological, and economic. In particular, the moisture availability of the soil increased by 27 % due to better accumulation of atmospheric precipitation, the yield of cultivated crops also increased by 20-30 %, and the aftereffect period increased to 4 years. This is a cost-effective and investment-friendly adaptive measure to ensure a satisfactory ecological and reclamation state of drained mineral soils (with an investment payback of 1 year). This provides modern principles of adaptive land use in changing climatic conditions and can be an effective alternative to expensive reconstruction and modernization of existing drainage systems.

Every year, the world sees an increase in the volume of hazardous goods transported by road. However, emergencies may arise related to the depressurization of containers (tanks, containers, cylinders, etc.) during the transportation of dangerous goods under various circumstances (traffic accidents, natural disasters, acts of terrorism, etc.). Furthermore, it can cause the ingress of hazardous chemicals into the environment and create significant risks for the population of the surrounding areas and habitat. The existing methods for assessing chemical accident consequences need to be revised. Therefore, they are not practical tools for solving problems of prompt response to emergencies associated with accidents while transporting dangerous substances by road transport. Unlike the existing ones, the authors developed new mathematical tools that consider all the main factors. They allow for determining the area of the affected zone, forecasting changes in its scale, and assessing risks to public health due to such emergencies. Comparison of the simulation results with the field measurements data showed high accuracy of the developed mathematical support.

Approaches to harmonization of methods for determining the optimal level of investment in the renewal of the fleet of combine harvesters and current expenses of agricultural enterprises under conditions of implementation of sustainable development goals in the activities of economic entities are investigated. It is established that the implementation of the concept of sustainable development for the domestic agricultural sector intensifies the processes in it, brings to the fore the problems of ensuring food security of the State, increasing the production of safe products while preserving landscapes and minimizing anthropogenic pressure. At the same time, the seizure of part of the territory, mining of the liberated and adjacent to the combat zone areas raises the issue of rational use of land resources. Under such conditions, only further introduction of innovations aimed at increasing yields and the use of intensive technologies is the most important vector for the development of domestic agriculture. This places strict requirements on the technical condition of its resource potential. Unfortunately, the unsatisfactory technical condition of the grain harvesting machinery fleet and its destruction as a result of hostilities exacerbate the problem of technical support for grain production, in particular for harvesting. Under such conditions, an important task is to develop methodological techniques for determining the optimal, harmonized values of investments in the reproduction of resource potential and operating costs. The tested methodological approach allows determining the optimal level of investment in the renovation of the combine harvester fleet, taking into account the peculiarities of wheat production organization, grain price conditions, material resources, harvesting equipment, and financial factors. The calculations showed that it is economically inexpedient to invest in the renewal of the combine harvester fleet using the most common combine harvester models if one unit has less than 600 hectares of wheat crops. A positive feature of the tested approach is the ability to minimize unproductive costs by taking into account technological and market factors in determining the optimal level of costs. Instead, the introduction of innovations leads to a change in the form of the production function, which should affect the dynamics of the marginal efficiency of investments, and therefore it is promising to expand approaches to modeling and take into account the role of innovations in finding the optimal level of current costs and investments.

The significance of protection of environmental components (soil, water, air, biodiversity, landscape) in global aspect directs the development towards sustainable agriculture, and organic production in particular. Organic production as a way of achieving sustainable growth is determined in the three main aspects of sustainable development: economic, social and ecologic sustainability. The conducted in the article analysis of statistical data on the development of domestic market of organic agricultural products shows that organic production in Ukraine is developing at a fast pace and stays one of the priorities for the further development of agro-industrial complex. At the same time, difficult current conditions of functioning of domestic organic enterprises can influence negatively the further development of this sphere, that will result in decrease of organic products export and will have negative impact on food security of other countries. Considering the mentioned, the purpose of the article is the substantiation of tools and measures which will ensure the formation of favorable environment for conducting organic production in the war and post-war periods. With the aim of systematization of the tools for the formation of “favorable environment” for the development of organic agricultural production their study is conducted with further grouping into regulatory and legal, political, stimulating and compensatory, fiscal and restrictive, financial and investment, infrastructural, informational, social and cultural, marketing, and digital. In the course of further research, within each group of tools a specific list of measures that must be implemented to simulate the development of organic agriculture and the circle of subjects responsible for their implementation were determined. It was proven that the formation and implementation of the defined tools and measures should take place at the international, national, regional, and local levels. The content characteristics of each group of tools, which are highlighted in the article, are important guidelines for the formation of effective state social and economic policy and international cooperation development in the conditions of aggravation of influence of global challenges and provide the certain opportunity for definition of ways of their improvement.

Assessing the economic development of countries in the context of the tasks defined in the UN 2030 Agenda for Sustainable Development is essential from the point of view of determining progress in achieving the SDGs. It becomes especially relevant in periods of global challenges and disturbances, one of which is the COVID-19 pandemic. The goals of SDG8 and SDG9 contain indicators that are determined mainly by the state of development of the country’s economy, so the analysis of trends in their changes is important in the context of identifying trends in economic growth in general, as well as for evaluating progress in achieving these goals. The purpose of the study is to identify the impact of the COVID-19 pandemic on the economic development of countries to achieve sustainable development goals and assess progress trends in the post-pandemic recovery of the economies of Eastern Europe by analyzing quantitative data from official statistical sources. The object of the study is the economic development of Eastern European countries in the conditions of the COVID-19 pandemic. The study period covers the time range from 2017 to 2021 and includes both the pre-pandemic and pandemic periods. Eight countries of Eastern Europe were chosen as research objects. Indicators of official statistics related to SDG8 and SDG9 sub-goals were selected for analysis. The study showed a significant decrease in the values of most indicators, which was caused by the destructive effect of the pandemic. To assess the possible development trajectory, we calculated the estimated value of indicators for 2022 using the Holt-Winters method. The results showed that, despite some progress in 2021, in 2022, the values of the indicators are decreasing. Such estimates correspond to the trends provided by international institutions. We have built a composite indicator to assess the economic development trend comprehensively. The results of the evaluation confirmed the general trend towards a decrease in the level of economic growth in the context of the goals of SDG8 and SDG9 for all the countries of Eastern Europe selected in the study.
