“…The aim of this research is a multi-sensor and multi-temporal approach in monitoring of deformation zone with permanent monitoring solution and management of environmental changes in the Solotvyno mining area. Many studies focusing mainly on sinkhole formation have been published in the field of defining surface deformation in the Solotvyno Salt Mine, forecasting, and development, accompanied by surface deformation processes (Yakovlev et al, 2016;Velasco et al, 2017;Onencan et al, 2018;Stoeckl et al, 2020;Pakshyn et al, 2021;Trofymchuk et al, 2021;Dobos et al, 2022;Molenda and Kidawa, 2022). These studies to date are mainly concerned with the description of the hydrological situation after the collapse of the salt mine, surface deformation monitoring, risk mapping and stress-strain state analysis in the surroundings of the Solotvyno Salt Mine, and for this, they use only InSAR technology to numerically quantify subsidence.…”

“…The deformation model results show that the deformation rate is almost linear throughout the study area. The dramatic increase in the freshwater infiltration inflow and the related active development of technogenic karst caused the formation of destructive deformations of the land surface and rocks of the residential and industrial buildings foundation, roads and water-pumping networks of Solotvyno village (Trofymchuk et al, 2021). Around the main sinkhole, the maximum deformation rate is around 5 cm/year.…”

Salt deposits were a rich source of mineral resources in the past, and some are still mined today. However, salt mines, especially abandoned ones, pose a threat to populated areas, infrastructure and the natural environment. Solotvyno (Ukraine) is one of the most significantly affected areas, with a deformation zone where significant year-on-year subsidences occur. Mining activities have caused a disturbance of the balance in the mountain massif, and as a consequence, the mountains are being reshaped, and the land cover is deformed. Deformation zone of the historical salt mine Solotvyno (Ukraine), Tyachiv district of Zakarpattia region is situated on the right bank of the Tisza river in the border area with Romania in Central Europe. This paper deals with the multi-sensor monitoring of the active deformation zone over the Solotvyno salt mine using satellite radar data (Sentinel-1), optical satellite imagery (Pleiades, SPOT) and in-situ UAV photogrammetry. Since the area represents a significant geohazard from a hydrogeological (Tisza River) and civil security standpoints (infrastructure of the inhabited regions), the design of a high-precision monitoring system to monitor and evaluate current environmental changes is proposed. Multi-temporal InSAR analysis exposed steeper subsidence tendencies of >−2 cm in the central part of the monitored area. Optical satellite and UAV images confirmed the increase in water surface in sinkhole areas up to 28,500 m2 and proved the emergence of new sinkholes in the central part of the Solotvyno mine. The aim of this study is to describe the post-collapse deformation processes by Pleiades and SPOT multi-spectral sensors and Sentinel-1 satellite SAR sensors since the 2010 collapse in order to describe the trends of deformation due to undermining and propose a high-precision permanent monitoring system based on satellite radar interferometry (InSAR).

“…O. Trofymchuk et al (2021) argue that technogenic tritium formed as a result of nuclear fuel reprocessing at nuclear power plants depends on the type of reactor and its parameters. Tritium fills the biosphere as a by-product of the use of atomic energy, the isotope actively affects natural processes, genetic structures, as it is easily assimilated in water, turning it into tritiated water.…”

The radioactive decay of elements as a result of a nuclear reaction is a powerful source of energy used in the production of electricity and heat in cities close to NPPs. The problem of using this kind of energy is the danger of radiation exposure. The production of nuclear energy has many advantages, including the profitability of the final product and its low cost; on the other hand, the half-life products of radionuclides in the composition of gas-aerosol emissions from ventilation pipes settle in the environment on the territory of city-forming nuclear power plants. The duality of the problems of the impact of radiation background on the urban areas near NPPs has become the purpose of this study. It is necessary to investigate the negative effect of radioactive waste emissions during the normal operation of nuclear power plants. For this purpose, the method of a project experiment was used, during which, using laboratory monitoring of external radiation safety and an automated radiation monitoring system, indicators of exposure dose capacities were collected from points in the 30-kilometre zone around the NPP. As a result of the monitoring of radiation samples from soil, atmospheric air and precipitation, and reservoirs, it was revealed that the natural radiation background is insignificant; the probability of harm from radiation exposure is small and insufficient for the development of radiation sickness. However, potentially unsafe sources of radiation exposure have been identified, such as natural radiation – the consumption of contaminated food, solar and cosmic radiation from radioactive elements present in the bowels of the earth; radionuclides, whose emissions uncontrollably occur into the atmosphere; radioactive waste, the disposal and storage technology of which is economically costly. Therefore, it is justified to conduct regular design experiments to check the operability of automated radiation monitoring systems. The materials of the study are of practical value for chemists, environmentalists, and ecotechnologists working at NPPs that monitor safety for human health and environmental protection in the field of atomic energy use

This paper is devoted to assessing the influence of waste rock surface dumps on the geomechanical state of underground mine workings. The conditions of the Pivdenno-Bilozerskyi high-grade iron ore field are chosen as the research object. To study the influence of dump placement and the depth of mine working on the mass stress state on the contour of sublevel drifts, a numerical modeling methodology based on the SolidWorks software package has been developed. This methodology involves the substantiation of the elements and properties of the geomechanical model, as well as the calculation scheme. Polynomial patterns of changing stress value in the hanging wall drift sides have been determined in the depth intervals of 440–740 m depending on the distance of the dump to the geometric center of the stope chamber. It has been revealed that the degree of the waste rock dump influence on the stress state gradually decreases with depth. It has been found that the maximum degree of the waste rock dump influence is observed on the upper horizons. When the waste rock dump is located above the geometric center of the future stope chamber that the stress value on the contour of the hanging wall drift can increase up to 10% compared to the absence of a dump on the earth’s surface. The research results are important for designing stable parameters for supporting sublevel drifts in difficult conditions of occurrence of the hanging wall rocks.
