Purpose. The aim of the work is to quantify the indicators of the environmental impact of mining enterprises on the state of the natural environment during the operation of a mining enterprise and after its liquidation. Method. The paper uses a computational and analytical research method. Results. Based on the calculations performed, it was established that the specific assessment of the environmental impact on the biosphere components of the Mining Enterprise PJSC "MM "Pokrovskoe" for the entire estimated period of the mine's existence: lithosphere – 0.071; hydrosphere – 0.02; atmosphere – 0.77; biota – 0.009; physical fields – 0.13. After the liquidation of the mine, due to the termination of coal mining operations from methane-free coal seams, the absence of emergency gas emissions, as well as a decrease in noise and heat pollution, the specific impact on the atmosphere (0) and physical fields (0.0004) is significantly reduced, but at the same time, the impact on the hydrosphere (0.26) and lithosphere (0.72) significantly increases, which is associated with changes in the hydrological regime of water and the deterioration of mine discharges of water quality in the hydrographic network due to pumping mine effluents to the daytime surface, with the dry method closing the mine, and waterlogging of the territory with a wet and combined method of closing the mine. The indicator of specific impact on the biota (0.009) does not change. Scientific novelty. A methodology for calculating indicators of the environmental impact of mining enterprises on the state of the natural environment is proposed. Practical significance. The obtained indicators of environmental impact on the components of the biosphere can serve as a basis for developing measures to reduce the negative manifestations of mining enterprises on the state of the natural environment. Key words environmental risk, mining enterprise, biosphere components, environmental impact.

Impact Of Mining

Land subsidence caused by groundwater withdrawal induced by mining is a relatively unknown phenomenon. This is primarily due to the small scale of such movements compared to the land subsidence caused by deposit extraction. Nonetheless, the environmental impact of drainage-related land subsidence remains underestimated. The research was carried out in the “Bogdanka” coal mine in Poland. First, the historical impact of mining on land subsidence and groundwater head changes was investigated. The outcomes of these studies were used to construct the influence method model. With field data, our model was successfully calibrated and validated. Finally, it was used for land subsidence estimation for 2030. As per the findings, the field of mining exploitation has the greatest land subsidence. In 2014, the maximum value of the phenomenon was 0.313 cm. However, this value will reach 0.364 m by 2030. The spatial extent of land subsidence caused by mining-induced drainage extends up to 20 km beyond the mining area’s boundaries. The presented model provided land subsidence patterns without the need for a complex numerical subsidence model. As a result, the method presented can be effectively used for land subsidence regulation plans considering the impact of mining on the aquifer system.

The research was based on general scientific and economic methods, the creative heritage of the founders of economic science, publications of Ukrainian and foreign scientists on the impact of quarantine restrictions related to the spread of the COVID-19 pandemic on the level of food security of the country, regulatory legal acts, data from the State Statistics Service of Ukraine, electronic resources and other sources. The monographic approach is used to analyze the dynamics of the actual consumption of agri-food products and the level of food independence for individual agri-food products. Normative and positive approaches are used to highlight real risks and threats to food security. A number of techniques of abstract-logical tools made it possible to make a scientific and applied generalization of the material presented, to formulate intermediate and final conclusions and proposals. Research results. An analytical assessing the impact of the COVID-19 pandemic on the consumption of agri-food products and the level of food independence for individual agri-food products has been carried out. It has been proven that Ukraine produces enough food to ensure healthy nutrition for citizens. It has been determined that due to the low purchasing power of the population, groups of citizens with low incomes have limited access to essential agricultural and food products. In the medium and long term, there will be a shortage of food resources and global food inflation, the situation in agricultural markets will remain unstable, and trade will continue to develop under the influence of not only competition, but also political factors. Scientific novelty. The theoretical and methodological provisions, scientific, methodological and practical approaches to determining the factors of influence of quarantine measures and the spread of COVID-19 to the level of food security of the state have been substantiated. Assessing the impact of quarantine measures and the spread of COVID-19 on food security made it possible to identify the main risks of ensuring the country's food security. Practical significance. The applied aspects of the study can be taken into account in the formation of programs for the socio-economic development of the agri-food sector of Ukraine, which will increase the effectiveness of state initiatives aimed at ensuring food security of the state and increase the country's readiness for force majeure threats.

The purpose of the study is to influence land resources during mining operations, and the main stages of land reclamation during mining on the example of the Tyradinsky gold Deposit, the "Zolotaya Tyrada" quarry, located in the Yenisei region of the Krasnoyarsk territory. The main factors of impact on land resources in the process of mining the field are considered; the analysis of measures to reduce the negative impact on land resources in the process of mining the field is carried out. The actual height and area of overburden dump not to exceed project, the reconfiguration of dumps allowed us to reduce the impact of mining on the environment, to avoid placing parts of the dumps in the water protection zone of the river Terada, thus there is no need of land allocation to forests of the first group and reduced the amount of removed topsoil. During the reclamation, potentially fertile soils (loam) taken from the quarry were used. There will be no deterioration in the impact on land resources during the liquidation process, due to the short duration of the work and within the existing land allotment.

Tax Regulation

The purpose of the article is to examine the state of the tax system in an unstable economy. The initial condition is the lack of uniform methodological and methodological approaches to the formation and organization of the tax system. This study is based on the theoretical provisions of the institutional theory, systemic and synergistic approaches. The main research methods used were analysis and synthesis, methods of induction and deduction, the method of designing hypotheses. The article examines the dynamics and structure of tax payments in the traditional approach to tax regulation. The question of determining the role of direct and indirect taxes is undoubtedly important for a comprehensive analysis of the taxation system since the influence of each of them on the economy is differentiated. The directions of modernization of the system of taxation regulation, the impact of mechanisms, methods, and instruments of tax regulation on various segments of the national economy, primarily on industries that ensure economic growth, have been investigated. The lack of a clear structuring of the elements of tax revenues becomes a serious obstacle to obtaining an adequate assessment of the impact of tax policy on various aspects of the country's socio-economic development. The state tax policy should be aimed at balancing the budget, improving the quality of its implementation, adhering to the timing of the budgetary process and, as a result, ensuring socioeconomic growth. The theoretical and practical significance of the study is to substantiate the need to adapt the tax system to ensure sustainable growth of the national economy.

Abstract This article concerns numerical modeling of the impact of mining operations on fault behavior, carried out on the basis of a calculation program based on the finite element method. The calculations and their graphic results related to the reactions of vertical discontinuity on the mining operations that run along its boundary under changing operating parameters, such as geometry of the field and direction of mining with respect to the fault, as well as the method of liquidation of the caving zone. The behavior of the fault was analyzed based on distributions in the plane of shear stress and slip, together with their range and energy dissipated due to friction. The results of numerical calculations made it possible to draw conclusions on the impact of faults and the impact of operating conditions of mining in their vicinity on the level of seismic hazard.
