The safety factors for different variants of operation development were obtained, on the basis of which the technical and economic indicators were established and the most expedient way of restoration of dump operations in conditions of the formed landslide was chosen. The solutions were proposed for the external dump No 2 of the Central Ore Mining and Processing Enterprise (COMPE), that allow to continue its future operation. When working in the conditions of the formed landslide, three variants of the further dump operation are modeled: the first one - with landslide removal and unloading of the upper dump horizons, the second one - without landslide removal and involvement of disturbed lands in land allotment, the third one - with the landslide loading. Based on the built sections of the dump and defined physical and mechanical properties, the stability factors were obtained for different options of the operation development, which made it possible to determine the appropriate option to eliminate the effects of the dump slide deformations. As a result of the calculations, the cost flows for each of the proposed options of the formation of the end contour of the dump No 2 are determined.
The purpose of the paper is to find out and identify conceptual approaches to the study of the innovative development of regional socioeconomic systems to take into account global requirements for global water security. Methodology. We used in our study traditional and special methods, including: historical and logical method, abstraction and analogy, and system analysis methods. Results. The article deals with the problems of innovative development of regional socioeconomic systems. Conceptual approaches to the study of the innovative development of these systems are determined. Theoretical approaches to regionalization are generalized and the regional typology in world regionalism is presented. The study devotes a sufficient attention to the issues of infrastructure support for regional systems, which is a prerequisite for the functioning and development of such systems. The article focuses on the priority of research of such a component of regional infrastructure as engineering and technical infrastructure. The model of regulation of development of regional socioeconomic systems on the basis of infrastructure support with the consideration of world requirements of global water security is offered. Practical implications. In recent times, the discussion on the definition of the essence of the concept of "region" is rather lively. The new paradigm of the regional economy represents the region as a variety of spatial systems of various scales. Yes, there are ongoing discussions that under the region can be understood as a group of states and small-sized administrative-territorial units. Despite the important role played by such regional systems in the economy of many countries, this topic in domestic studies is not given with enough attention. Also, in the domestic scientific schools of the regional economy, studies devoted to the problems of patterns and tendencies of the formation and development of regional systems of Ukraine, the solution of which can ensure the formation of a system of management of regional development taking into account national interests, are not sufficiently represented. Value/originality. This problem in the economic literature is investigated by many domestic scientists who devote a lot of attention to the problems of regional development management, including the following:
The correlation between the development of a regional economy and the degree of infrastructural development of a country or its territory is a common practice. Considering this, the paper is aimed at studying the impact of water infrastructure on the economic security of regional socio-economic systems in order to develop a water security system for them. A variety of threats against key waterworks can seriously undermine the national economy and water security of regions and cities. Thus, the study analyzes the process of transformation of water infrastructure in the context of ensuring the economic security of regional socio-economic systems. It offers the definition of such categories as “water infrastructure” and “water security of a regional socio-economic system” to formulate a relevant economic policy in Ukraine based on world experience. The study proves the need to attribute water infrastructure to the critical infrastructure sectors of Ukraine and its regions, based on the best world practices in managing water resources and protecting the water infrastructure itself from technogenic, physical, and cyber-physical threats. According to the study results, conceptual bases for ensuring the economic security of regional socio-economic systems are developed, which differ in view of the water security system of the regional socio-economic system, giving priority to the engineering and technical infrastructure of a region.
Purpose. The purpose of the article is an identifying the impact of regional water management dependence on economic growth in the region. Methodology / approach. The subject of the study is theoretical and methodological basics of a new scientific paradigm for regulation the development of the regional socio-economic systems under the conditions of limited water resources. The study used traditional and special research methods, including: historical and logical – to analyze the evolution of regional socio-economic systems under conditions of limited water resources; abstractions and analogies – to reveal the essence of water-efficient regional socio-economic systems in the modern processes of regionalization and globalization; theoretical generalization, analysis and synthesis – to specify the categorical apparatus; statistical analysis to assess the level of needs of regional socio-economic systems in water resources and create an index of regional water management dependence; method of correlation analysis (biserial correlation, using a point biserial Pearson’s correlation coefficient). Results. The main idea of the paper is to study the issues of development of regional socio-economic systems under the conditions of limited water resources. Considering this, the paper is aimed at studying the impact of regional water management dependence on economic growth in the region. The tasks for development of regional socio-economic systems on the basis of water efficiency are defined, as well as the concept “water-efficient regional socio-economic system” is defined. The study presents a hypothesis about the need to change the paradigm of regulation of regional development on the basis of water use efficiency and regional water management dependence. In order to trade effectively with the main crops, it is necessary to determine whether there are sufficient water supplies in a given country and its regions. For this purpose, the authors proposes to use own indicator, such as the index of regional water management dependence. Thе characteristic of water management dependence is given, from regions where only up to half of the water supply of the territory is used, and to regions where more than 100 % of the water supply of the territory is used. The research has updated that the expansion of knowledge and understanding of the specifics of the water sector can solve significant problems. It is proved that the economic growth of the Ukrainian economy due to the agricultural sector has its limits and is limited by the water management dependence of the territories, ie the limitation of certain territories of the regions of Ukraine in terms of water resources. The next effective economic growth is possible only through the implementation of water-efficient technologies and intensification of water-efficient activities in the region. Originality / scientific novelty. The study for the first time defines the concept of water-efficient regional socio-economic system, so it is a socio-economic system that provides for the restoration of water resources in the region, reducing the water intensity of gross regional product (GRP) and approaching European norms and proposes the classification of regions according to the index of regional water management dependence on the basis of its threshold values. A scientific and methodological approach to assessing the level of needs of regional socio-economic systems in water resources has been improved, based on the application of the index of regional water management dependence, which is proposed to calculate the ratio of total fresh water use in the region to the volume of available river runoff in the region (parts of the water potential). The classification of regional socio-economic systems according to the level of water supply has been improved, which is based on the definition of threshold values of the index of regional water management dependence. The methodological bases for assessing the impact of the spatial economy on regional development under conditions of limited water resources have been improved, which differ in substantiating the dependence of the level of development of regions on the available water potential of the territory. Practical value / implications. The results of the study allow a more comprehensive approach to the study of the problem of using water resources in Ukraine in the context of their limitation. The results of the study showed that the economic complex in most regions is water-intensive and unbalanced, as well as does not provide restoration of water resources by environmental parameters and requires the implementation of infrastructure schemes for redistribution of water resources between regions for economic activity. The results are recommended for consideration by local governments and regional administration for the development and implementation of “Regional programs for the development of water management in the region” and for the development of “Strategies for regional development until 2025–2027”.
