The Impact of Coal Quality on Reduction of Environmental Pollution Researched Through Statistical Analysis

Abstract

Today, the region in general but also Kosovo faces a lack of electricity on the one hand and environmental pollution on the other hand from existing power plants where electricity is produced for the community in general in thermo-plants Kosovo A and Kosovo B. The purpose and importance of this paper is that for the samples taken through the layers (floors) of coal by drilling to extract the calorific values of coal (ETU) and the percentage of ash, whose parameters were analysed in the laboratory of geo-mechanics according to the standards (ISO 9001) in order to eliminate the weak part of coal that would have a positive impact on increasing electricity production but also on reducing environmental pollution within the allowed values according to European Union standards. To carry out this work, a large number of drillings were performed from which 91 samples were taken at different depths, these samples were analysed and, at the same time, statistical processing was done in order to find the average caloric value of (ETU) and the content of ash with the lowest value, these parameters will help us to determine the method to be applied during the exploitation in order to create better conditions for the transport process to the power plants by means of conveyor belts and, at the same time raising the quantity of energy production and reduction of carbon dioxide (CO2).

Geomechanical research into surface coal mining in terms of geotechnical safety substantiation

“…2) and has an average elevation of 530-670 meters above sea level. The slopes of these hills lie at an angle of 4 to 10 degrees with a general decline in the direction from southeast to southwest [3], [4]. From a hydrological point of view, surface water includes both rainwater and water sources, which, due to the opening of working fronts, infiltrate the coal seam.…”

“…Further medium-term development of lignite mining continues in the active mining area of Sibovc (Obiliq) in the southwestern part of the Kosovo Basin, giving great priority to private investments. Based on current research and the status of mineral energy resource reserves according to [3], [4], the Republic of Kosovo has significant reserves of lignite type coal on its territory according to data in Table 1) and a part of them is used for the needs of the country (Fig. 1).…”

Yeasts in the Soils of the Alytus Region after the Fire of the Tyre Processing Plant

“…For example, Ahmeti et al (2022) found that coal with a calorific value of less than 6500 kJ/kg used for electricity and heat production should not be used due to its high environmental impact and promotion of climate change. Also, not only processes that use coal but also its extraction contribute to pollution [8].…”
