Ways to reduce technogenic landscape disturbances in mining production
Authors: Antonik V , Babets E , Antonik I , Melnikova I 
Published: July 2022

Abstract
Iron ore mining is followed by significant disturbances of the earth’s surface caused by both iron ore mining facilities (underground mines and open pits) and disposal of mining and concentration wastes on the surface (waste and substandard ore dumps at underground mines, overburden and oxidized rock dumps at open pits, tailings storage facilities at mining and beneficiation plants). In addition, operation of mining enterprises leads to creating hundreds of kilometers of above-ground pipelines, technological roads and railroads; drilling and blasting operations at underground mines and open pits lead to seismic phenomena and geotectonic disturbances of the surface in the form of sinkholes and craters in places of underground workings. The presented scientific work aims to generalize the practice of measures to optimize landscape disturbances caused by mining and develop individual issues of arrangement and technology of reclamation of disturbed surface areas in conditions of Kryvyi Rih iron ore basin. Technogenic surface disturbances accumulated during the period of economic exploitation of the region require a comprehensive solution in two directions. The first one consists in reducing the rate of new destructive impacts on the state of the relief by switching from extensive methods of deposit exploitation to all-round intensification of production (introduction of low-waste technologies, concentration waste re-treatment, oxidized ores processing, transition to technologies of internal dumping). The second one involves optimization of already formed landscape disturbances through reclamation. It is recommended to implement a number of methods of improving individual technogenic landscape formations by engineering and biological methods.

Abstract
The urgent environmental problem of industrial Kryvbas is the reduction of dust formation from wind erosion of bare surfaces, especially slopes, dumps of iron ore mines and quarries. The best way to reduce the dusting of dumps is to afforest their surface with trees and bushes, but naturally this process can take up to 15-20 years, and the well-known scientific developments to solve this problem are ineffective or too time-consuming. The objective of our work is to create the innovative technology for active stimulation of self-organized vegetation of hard-to-reach steep slopes of dumps. To implement the idea, it is proposed to use standard hydroseeders for a new purpose, in particular, HM-0-HARV Turbo Turf hydroseeder, which is able to create hydroflow at a distance of 30-50 m. The article describes in detail the essence of the developed technology, method of organizing and conducting hydraulic sowing from both the lower and upper edge of the dumps. It is recommended to include seeds of herbaceous grass and legumes, deciduous trees and shrubs, mineral fertilizers and nutrient substrate (sewage sludge) in the seeding hydraulic mixture. The proportion of seeds of various plant species, fertilizers and nutrient substrate in the hydraulic mixture for sowing on the slopes of Kryvyi Rih dumps, which have a neutral soil acidity and contain at least 3% of the fine fraction of rocks in the surface structure, is substantiated. According to the results of testing the proposed technology, it is concluded that applying a mixture of seeds of herbaceous plants, trees and shrubs in combination with mineral fertilizers and nutrient substrate to the surface of dump slopes by hydroflow accelerates their self-organized vegetation by about 3-4 times. It is shown that crop care measures in the first year of plant vegetation (periodic watering and, if necessary, fertilizing using hydroseeder) can save up to 60-75% of seedlings and help stabilize newly created biogeocenosis in subsequent years.

Abstract
The article is devoted to monitoring surface displacement and the condition of monitored objects. The object of research is the process of displacement of the earth’s surface and the state of protected objects of the “United” deposit of the mine department for underground mining of ores of PJSC “ArcelorMittal Kryvyi Rih”. The displacement process is monitored based on long-lasting instrumental observations to determine surface deformations and assess the safety of exploitation of the monitored objects within the mining allotment. The study findings enable ascertaining that in the southern and central parts of the minefield, the displacement process has stopped, but in the northern part, it is still developing, and mining will have no impact on the technological objects of the Mine Management in the next two years. Over the recent two years, actual subsidence rates in the railway area have not exceeded 2.7 mm/month, and they are significantly lower than the permissible values (100 mm/month). The road sections shifting and the base for the removal of the road continue to develop. Mining operations at the deposit “Obiednanyi” have no hazardous impact on the “Schistose Rocks” natural geological reserve, the settlement of Karnavatka and the cemetery “Zakhidne”. Displacement on road and road base sections is in progress. In the vicinity of the settlement of Zhukivka, the maximum relative deformations (3.2 mm/m) are still much lower than the permissible one (6 mm/m), and they will not reach their maximum permissible values in the nearest two three years. In the last year, deformation rates decreased and reached the 2018 figure. Therefore, all the monitored objects within the mining allotment can be safely exploited.

Abstract
Introduction. A yield frame support is a basic means of providing the underground roadways’ stability in the deep mines operating in the hard ground control condition when the ratio of the ground pressure to the unconfined strength of surrounding rock mass exceeds 0.33. The operators adjust the nominal bearing capacity of the frames at 0.55 of their maximum or peak resistance Fmax
because the frames operate in a dry friction mode spontaneously generating oscillation, which causes variation of the resistance in the range from 0.1 up to 0.9 of Fmax
. Aim/tasks. We intended to reduce the dynamic oscillation of the support resistance that allows for increasing their bearing capacity. Methodology. We used a computer simulation by FLA3D model, indoor testing of the frames, and actual measurements in an underground coal mine. Results. We revealed a specific behavior of the frame support that reduced the limit of the bearing capacity by 45%. During yielding, the frames generate dissipative structures (DS) that become apparent due to the dynamic nature of stick-slip friction following the yielding process. We demonstrated that DS control and especially its suppression provides a sustainable increase in the frame bearing capacity. Conclusions. Improvement of the yield frames design and especially their clamps are the prospective way to control DS and provide sustainable enhancement of the frame bearing capacity.

Abstract
Recently, there has been a significant reduction in the number of favorable areas for construction of buildings and structures, which leads to the need to build various facilities in special conditions, so in areas with difficult engineering-geological and mining-geological conditions of construction, which are deteriorating due to natural and man-made factors. It is necessary to assess the possibility of deformation of structures located on foundations with possible uneven deformation in the practice of design and operation. Only with reliable and accurate determination of the stress-strain state of foundation structures and soil mass the service life of buildings and structures can be predicted. Calculations performed with the help of PLAXIS and LIRA programs allowed to analyze the stress-strain state of the soil mass and the stability of the foundations with the same soil base (layer thickness and physical and mechanical properties), loads and boundary conditions: Option I – ordinary solid monolithic reinforced concrete foundation slab; Option II – proposed a solid monolithic reinforced concrete slab with a system of cross beams of different stiffness (patent № 13794). The validity of the theoretical forecast of the behavior of the foundation structure, which interacts with the unevenly deformed base, can not be obtained on the basis of the regulatory framework. The possibility of using a foundation with a system of cross beams of different stiffness in order to increase the reliable operation of high-rise buildings was experimentally and theoretically proved.

Abstract
Modern alluvium is a complex multicomponent system that includes both natural and man-made material. In the process of research on the pollution of river sediments with industrial waste, the authors established the presence of commercial products of mining and processing enterprises in the sediments. It includes crushed granite, metallurgical slags, ores and concentrates, coal and other products. Significant volumes of inputs of these materials into the ecosystem motivate the development of special technologies aimed at additional production of mineral products through the complex processing of modern river alluvium. In addition to economic benefits, the implementation of these projects will improve the state of the environment in regions with significant technogenic load.

Published: July 2022

AbstractThe comparative analysis of laws and regulations on air quality, air protection, and its monitoring in the EU and Ukraine has been carried out to analyse the state of the European Union – Ukraine Association Agreement. The main features of the strategic documents “Europe 2020” and “Ukraine 2020” air pollution control are discussed. The analysis of air quality monitoring regulations, air quality control methods, and peculiarities of citizens’ alerts in the EU and Ukrainian legislation is provided. It is proven that the methods approach to limiting pollutant values differs in Ukraine and the EU. EU uses limit value’, ‘target value’, alert threshold’, ‘information threshold’ and ‘critical level’ and Ukraine uses limiting values. The limit values/permissible concentrations of carbon dioxide, sulfur (IV) oxide (average daily value), and lead are stricter in Ukraine. However, the permissible concentrations of PM10, sulfur (IV) oxide (short-term value), Arsenic, Cadmium, and Nickel are much lighter in Ukraine than in the EU. The dioxin content in ambient air is not regulated in Ukrainian legislation. Also, citizens’ monitoring systems and data provision differ and should be harmonised for the EU’s standards. The current state of roadmap implementation is firstly presented. It is demonstrated the necessity to harmonise the Ukrainian law and regulations on air quality control and air protection with the EU law.
Spatial variation of soil temperature fields in a urban park
Authors: Kulish T 
Published: July 2022

Abstract
Soil temperature is the most important factor that regulates the rate of physical, chemical and biological processes in the soil. A peculiarity of the urban environment is the occurrence of “heat islands”. The increased temperature of urban environment significantly changes environmental conditions and contributes to the activation of phenomena that lead to the acceleration of global climate change. The aim of the work is to reveal the patterns of spatial variation of soil temperature in a city park at the different scale levels. Soil temperature was measured on a regular grid with different lags between measurement points. The measurement results were processed using geostatistical methods to quantify the spatial process at different scales. The results obtained allowed to quantify the patterns of spatial variability of temperature fields at different hierarchical levels. Scale-dependent effects of soil temperature variation were identified. The role of stand density, litter depth, and soil moisture on soil temperature variation was found. The results of the study are the basis for developing an optimal soil temperature measurement plan for environmental monitoring purposes. Suggestions were also made for the management of park stands in order to reduce the temperature load. The spatial variation in soil temperature demonstrates the occurrence of scale-dependent patterns. The spatial organization of temperature fields must be taken into account for optimal environmental monitoring and urban environmental management strategies. The soil temperature regime is characterised by a significant level of stability compared to air temperature. The soil temperature fields in an artificial park plantation are characterized by spatial patterns of a complex nature. The temperature field presents a spatial component that is invariant to time. It is most likely that the spatial variability of soil properties induced by natural factors and recreation are the cause of the generation of this pattern. Also in the soil temperature field there is a spatial pattern, which reflects the different sensitivity of the soil to the seasonal trend of temperature change. The generation of this pattern is due to the different insulating capacity of the forest litter in the park plantation. The results obtained point to the important role of leaf litter as a factor in the dynamics of the soil temperature regime. It is hypothesized that leaf litter in the park contributes to the enhancement of carbon sequestration during winter time.
Morphological response of lagoon cockle Cerastoderma glaucum (Poiret, 1789) to eutrophication in the Sea of Azov

Abstract
The bivalve species Cerastoderma glaucum (Poiret, 1789) was studied in this study. This species is allochthonous and belongs to the Mediterranean zoogeographic complex and was introduced in the Holocene. The C. glaucum is the dominant species among the bivalves in the Sea of Azov and has a wide range of distribution. The species is distributed in the coastal zone within 100-300 m from the shore, and it is also found in desalinated water bodies such as estuaries. The C. glaucum is fairly resistant to hypoxia. It is euryhaline with respect to salinity and eurybiontic with respect to soil. The species can settle on sandy, muddy or sandy-silty substrate. The aim of the study was to investigate the morphology of shells of this species in order to find out the reasons of morphological features change of Cerastoderma glaucum in different biotopes of the Sea of Azov. The study was conducted in early June 2021 on the northwestern coast of the Azov Sea. A total of 20 stations were investigated. Cerastoderma glaucum was found at all stations. The morphological variability of the bivalve Cerastoderma glaucum was investigated using the method of discriminant analysis. A notable morphological feature was the external alteration of the mollusc shell. A displacement of the apex to the anterior edge of the shell, lengthening of the posterior edge, and deformation of the shell shape, indicating the ecological characteristics of the study area and its inhabitants. Also, there is a difference in the ratio of shell height to shell length, indicating an increased level of siltation in the ground. Shell thickness varies in all survey areas, indicating different levels of salinity. The overall abundance of molluscs from the different biotopes indicates the factors determining the shape of cockle shells. In turn, morphological parameters indicate the general condition of the Sea of Azov. So, it can be assumed that siltation of the substrate on which benthic communities are located has increased as a consequence of massive deposition of phytoorganic residues. In addition, the hydrolytic regime has changed as a result of anthropogenic factors. As a consequence, salinity, oxygen levels are changing, etc.

Published: July 2022

Abstract
Today, the Azov-Black Sea coast of Ukraine is one of the most important migration routes in Europe, which is used by up to 15 million birds every season. The development of a scientific and information system for monitoring, assessing and predicting the state of biodiversity on the territories of wind power plants (WPP) in the Azov-Black Sea region is extremely important, and the study of seasonal ornithocomplexes is a key moment in the creation of wind farm sites. Assessment of the impact on them is paramount in the development of management plans and risk minimization. The studies were carried out in the Azov-Black Sea region of Ukraine at 12 monitoring sites in the period from 2010 to 2021 using modern international methods adopted in the European Community, used for these technogenic territories, as well as author’s developments. The studies that were carried out using the WEBBIRDS WEB-application for monitoring seasonal ornithocomplexes and computer modeling of assessing the impact of the wind farm site based on the server accumulation of monitoring data (an author’s development), software for calculating the risk assessment of bird collisions with wind turbines (CRM), assessing the potential biological removals (PBR) showed no significant adverse impact of wind farms on birds observed at all 12 sites. These monitoring studies make it possible to assert that the main impact on the stability of migratory bird complexes in the project area is exerted by various biotic and abiotic factors such as landscape-biotopic, forage, weather factors, and the impact of wind farms is minimal.
Effect of recreation on the spatial variation of soil physical properties

Published: July 2022

AbstractRecreation affects various components of ecosystems. A significant transformation occurs in the soil cover in urban parks. The physical properties of soil are sensitive indicators of the level of anthropogenic transformation, and also allow to assess the state of soil as a habitat for plants and soil animals. The question of quantitative patterns of soil properties variability under the influence of recreation is not solved. There is also little information on the spatial aspect of the variability of soil physical properties in urban ecosystems. The aim of our study is to test the hypothesis that the recreational loads cause the formation of spatial patterns of soil properties, which by their extent greatly exceed the zone of direct influence. The spontaneous walkways within an urban park were investigated as an example of recreational loading. The physical soil properties were measured on a regular grid. The distance to the walkway was treated as a proxy variable that indicates recreational load. The application of multivariate statistical methods allowed to reveal the components of the variation of soil properties of different nature. The effect of recreational load is superimposed on the natural variability of properties. The peculiarity of the influence of recreation consists in sharp increase of soil penetration resistance in the upper soil layers and decrease of this index in the lower layers. The recreational load affects the physical properties of the soil. The soil compaction is the main direction of transformation. This effect gradually attenuates with distance from the source of exposure while occupying a significant portion of the space. The variation of soil properties affects the redistribution of soil moisture and soil air, which significantly affects the living conditions of soil biota.
