Modern environmental risks and threats relate with the negative impact of anthropogenic and natural factors on ecosystems, man-caused negative impact of industrial and potentially hazardous objects, pollution of drinking water sources, agricultural land, atmospheric air, deviation of the geological environment and subsoil on the safety of life in certain areas. Coal enterprises are one of the objects of high ecological danger and critical infrastructure. Today, environmental safety in the east of Ukraine should be considered in close connection with the ecological and man-made threats associated with combat operations in these territories. The authors carried out an analysis of scientific researches of past years and provided an assessment of environmental risks in the territories of coal mining enterprises in the present conditions considering the structural-geological, geofiltration and mining-geological parameters typically for the Donetsk and Luhansk regions of Ukraine. The article considers the location of mines in Donetsk and Lugansk regions as zones of high ecological danger. The existing ecological threats and risks are determined, recommendations for minimization threats and risks in case of anthropogenic and environmental disasters are provided. The equation of calculating the coefficient of filtration in rocks is made, mineral-technical parameters of coal mines are analyzed. It is shown that one of the most probable factors of the transition of the territory into a zone of an emergency situation of a regional scale is the emergence of real threats to the life of a large number of people in the conditions of mass flooding of mines due to the termination of power supply of drainage and ventilation systems. Also in the article scientifically substantiated the provision of an acceptable level of environmental safety of the constituent parts of the environment (water environment) for the population living within the mining and agglomeration, taking into account the environ- mental factors of the negative factor-forming factors, as well as forecasting the hydrodynamic situation.
The article solves an actual scientific and applied task, which is to form a methodological basis for the use of orthotransformed satellite imagery to create information services for environmental monitoring of objects of critical infrastructure. These services are designed to expand the capacity of the National Center for providing the information to central executive authorities about the results of environmental monitoring. The expansion involves the development of methods of using orthotransformed satellite imagery for the assessment of the environmental state. Based on the classification algorithm of enterprises and objects, a database of objects of critical infrastructure of Ukraine classified by their impact on the environment has been developed for the application in GIS-compatible systems. In the formation of the ideology of geographic information systems, the requirements for technical means are justified. These requirements include the deployed service, maintenance, filling and updating of the base of objects of critical infrastructure of Ukraine, the mechanism and order of visualization of impact assessments of all objects of the developed database. The algorithm has been adapted for application in an automated mode as part of GIS-systems. For research, the structure of the classifier using the state OCI register and validation of the developed methodology using the results of space imagery with specific examples for each of the objects of critical infrastructure of Ukraine has been developed. The following object is selected: Darnytsya Power Plant-an enterprise for the production and supply of electric and thermal energy. The study confirmed the relevance, scientific and practical value of using remote sensing methods for studying the ecological status of large areas of the earth's surface.
The article analyzes the consequences of pollution from industrial enterprises, as well as the risks of disruption of operation and flooding of mines. The armed conflict in the East of Ukraine led to serious environmental consequences – it is the pollution of groundwater, water bodies, air pollution, decommissioning of large areas of arable land, destruction and damage to objects of the nature reserve fund, forest fires, etc. It has been shown that in areas where the armed conflict continues, there has been significant pollution of the environment with chemical toxic substances, metal fragments and heavy metals due to artillery shelling and the use of explosives. As a result, numerous funnels were formed, which mutilated the land and destroyed natural protected areas, flooded mines, built fortifications, ditches, and damaged sewage and water supply networks. Risks associated with damage to communications, businesses and other facilities that pose an increased environmental risk, increase the scale of the negative impact. The problem of flooding of mines and excessive mineralization of waters, which are the part of the production process, is very relevant for both Luhansk and Donetsk regions. Solving this problem requires significant efforts from both the Ukrainian state and international environmental organizations. The main problem is that the mines are located in both controlled and uncontrolled by the Ukrainian government. The fate of coal mines in the territory not controlled by t government of Ukraine is uncertain and requires control by international organizations that are able to conduct monitoring activities. The coal industry in the EU is at «coal-out phase», i. e. at the stage of gradual abandonment of coal mining. First of all, this is dictated by the EU’s course to reach a carbon-free economy by 2050, which means the gradual abandonment of coal generation and the transition to renewable energy sources. And also in accordance with the EU Directive No787 in 2010 On the need to close unprofitable mines.
The technological processes of coal mining, enrichment and use, in particular coal combusting is accompanied by formation and release of significant amounts of dust and gases. Atmospheric air protection is one of the most urgent problems of the nowadays technological society, as scientific and technological progress and expansion of production is associated with an increase in negative anthropogenic impacts on the atmosphere. The paper presents a new solution to the current scientific problem of reducing carbon-containing dust content based on the disclosure of the laws of the aerodynamic interaction of dust and water flows in gravitational and electrostatic fields. The authors show in this study the causes of atmosphere pollution with coal-containing dust; main issues of atmospheric air protection at enterprises located in the controlled territory of Ukraine. The data of the first quarter of the 2020 year are presented in the research. The biggest part of the facilities that pollute the atmospheric air are focused in Donetsk and Lugansk regions. It is estimated that the air environment of the underground mine surface complex is filled with exhaust ventilation air of approximately 200.000 m3 per minute with a dust concentration of approximately (5-7) mg / m3, which is equal to 1.5 tons of dust per a day. It is here that the possibility of transporting pollutants over long distances is most often realized. Coarse dust discharged through the ventilation systems of mines is intensively deposited in the sanitary protection zones of mines. Fine dust is carried by the wind outside them, polluting the environment on the distance of up to 3500 m from the coal mine. Emissions of carbon dust into the atmosphere are almost always a major part of transboundary environmental pollution. Mine waste also poses an environmental threat. Technologies of reduction air pollution at the source of carbon-containing dust formation should be used in all new industries of economy. The results obtained reveal the mechanism of interaction of the sprayed liquid with coal dust and can be used in the development of new effective means of controlling the carbon-containing dust. The principles and practices of sustainable development, coupled with local research, will help to contain or eliminate health and environmental risks resulting from air pollution by carbon-containing dust.
The research presented here is focused on assessment of potential territorial risk in the East part of Ukraine, where the military conflict has been going on for five years. Such kind of risk can be classed as a complex risk level of hazardous facilities or territories. This study determines the boundaries of territorial risk distribution with defined levels of danger. The practical implementation is reflected in the web-based geographic information system (web-GIS) for displaying environmental information in Donetsk and Luhansk regions in real time. The research defines an opportunity for further practical application of this development considering the military conflict in the Donbas. The Donbas Environmental Information System (DEIS) is an interactive map of Donetsk and Luhansk Regions. It was developed within the framework of the Project “Environmental Assessment and Recovery Priorities for Eastern Ukraine” by the OSCE Project Co-ordinator in Ukraine upon the request of the Ministry of Ecology and Natural Resources of Ukraine. The supporting of the system is carried out by the State Ecological Academy of Postgraduate Education and Management (DEA) of the Ministry of Ecology and Natural Resources of Ukraine, in particular the Center for Environmental and Resource Restoration of the Donbas within the framework of the Project of the OSCE Project Co-ordinator in Ukraine “Assisting the Ministry of Ecology and Natural Resources of Ukraine in improving environmental monitoring mechanisms”.The main task of this study is to implement the software for collecting, processing and visualization of the information about the environment and factors that may affect it. This will make it possible to increase the effectiveness of environmental management in order to meet the environmental safety requirements in Donetsk and Luhansk regions.
