In the case of coal fuels, as one of the main energy source, effective technologies for maintaining mining operations under difficult conditions are substantiated. The energy efficiency of coal gasification with the use of mining waste has been estimated, technical and technological means, as well as conditions for the introduction of the gas generator are proposed. In the aspect of the normalization of working conditions of miners, protective effectiveness of respiratory devices is established, taking into account the requirements of the European standard EN 529: 2006. The possibility of significant energy savings is demonstrated by the introduction of electric drives with group power from a conventional DC device with storage capacity." /> <link rel="canonical"

considered. Technical and technological performance of such gas generator and mechanism of material and heat balance on the basis of the available analytical methods and practices as well as the developed author software have been proposed. Heat carrier formed in the process of coal gasification has been used for the utilization. Temperature of the utilization process within the industrially expedient limits being supported with the help of either activation or attenuation of the gasification process. After specific treatment, organogenic waste and domestic wastes are utilized by means of thermal decomposition within a gas generator. Economic evaluation of the proposed means confirms the expediency of their implementation in mines with industrial and balanced coal reserves as well as within the areas where this energetic source has already been already mined out. Results of this investigation were partially presented on international scientific and practical conference “Forum of Miners - 2017”. They contain the researches, which were conducted within the project GP – 489, financed by Ministry of Education and Science of Ukraine. </div> <div> <a data-readmore="{ block: '#abstractTextBlock530907', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 1 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AEF.25.11">Energy-Saving Technologies of the Coal Seams Development</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Olexander Shashenko, Nataliia Khoziaikina, Vladyslava Cherednyk, Maryna Pashkevych </div> </div> <div id="abstractTextBlock530891" class="volume-info volume-info-text volume-info-description"> Abstract: In the production cost structure of a coal, which is extracted underground, more than 30 percent is the electricity cost. This is the consumption of electricity by the main fans of mine ventilation, mining and mechanisms that are used in the construction of underground excavations.The geomechanical problem of estimating the permissible width of the safety structure (pillar) in a longwall during the mining of a horizontal laying coal seam is given and solved and taking into account the economic expediency of reused a haulage drift. The mining-geological and mining-technical conditions of coal reserves mining in the Western Donbass at the mine "Samarskaya" are considered, which is accepted as a characteristic object of research.The task was solved in a complex way on the basis of a generalization of in situ and numerical experiments on digital models using the RS2 software complex of the Canadian company Rocscience.Dependencies of a residual sectional area of the re-used excavation on the width and the constructive flexibility of the protective structure are obtained.A technological clearance between the safety structure and the roof rock negatively effects on excavation stability reducing the residual sectional area and should be minimized. </div> <div> <a data-readmore="{ block: '#abstractTextBlock530891', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 11 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AEF.25.20">Some Aspects of Energy Efficient Project Management</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Mykola Trehub, Kseniia Tiukhmenova, Kostiantyn Kravchenko </div> </div> <div id="abstractTextBlock531032" class="volume-info volume-info-text volume-info-description"> Abstract: According to energy-saving trends the use of all types of energy should be minimal and efficient. Since late 90-s such strategy has been already used in well-developed countries. In Ukraine the energy-saving measures became popular since 2014. Now it is possible to receive warm loans supported by Ukrainian government for private households and co-owners of multi-apartment buildings. Also, it is possible to apply for grants of the Ministry of Regional Development, Construction and Housing and Communal Services of Ukraine – the regional development projects that can be implemented at the expense of the state budget received from the European Union or other grants financed by local authorities at different levels. According to statistics it was found that using thermal sanitation method as a key measure of energy saving, it is possible to provide 85% of insulation efficiency. The research is focused on determination of weaknesses concerning grants for energy efficiency, their application and management. One of the most important factor that influence overall success is the correct calculation of energy losses. Three possible types of errors during calculations and possibilities to reduce their influence were defined. At the end of the article conclusions and suggestions for further research were made. </div> <div> <a data-readmore="{ block: '#abstractTextBlock531032', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 20 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AEF.25.28">The Prospects of Thermal Water Exploration in Ukraine</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Ivan Sadovenko, Dmytro Rudakov, Oleksandr Inkin </div> </div> <div id="abstractTextBlock530867" class="volume-info volume-info-text volume-info-description"> Abstract: The total resources of geothermal energy in Ukraine up to the depth of 10 km are estimated at 10<sup>22 </sup>J, which significantly exceeds the reserves of fossil fuel sources. Nevertheless, geothermal exploration in each specific case requires comprehensive thermodynamic and feasibility studies taking into account local geological, hydrogeological conditions, and depth ranges. To facilitate such kind of studies an analysis has been made for Ukraine’s territory with the identification of aquifers that can be potentially used including the Transcarpathian trough, the Volyn-Podil’ska plate, the Dnipro-Donets depression, and Black Sea coast area. Regarding high thermal water mineralization a geo-technological scheme has been justified for environmentally safe exploration that suggests a closed cycle including (i) pumping out water to the surface, (ii) heat extraction, and (iii) re-injection of water into the aquifer. A mathematical model developed to evaluate the geo-circulation system effectiveness for various conditions allows predicting the changes in water temperature during circulation, power consumption, and heat capacity. Besides, the model enables optimizing the system performance depending on pumped water temperature. We assessed the effectiveness of geothermal heat extraction with the geo-circulation system in terms of profitability and net the present value (NPV). According to the estimations made for aquifers in Ukraine the geo-circulation system can be operated with the positive NPV in many regions of the country depending on the aquifer depth, heat flux, and groundwater flow. The obtained results correlate to the world standards of rational exploitation of geothermal energy. </div> <div> <a data-readmore="{ block: '#abstractTextBlock530867', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 28 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AEF.25.35">Energy Efficient Technologies to Support Mine Workings under Complicated Geomechanical Conditions</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Olexandr Solodyankin, Sergey Hapieiev, Mikhail Vygodin, Valentin Yanko </div> </div> <div id="abstractTextBlock530870" class="volume-info volume-info-text volume-info-description"> Abstract: Objective of the studies is the substantiation of energy efficient technologies to support permanent mine workings under complicated conditions of mines in Western Donbass.

It is possible to formulate names of mining methods on proposed which allows to present a complex of the productions which are carried out during mining of production blocks. </div> <div> <a data-readmore="{ block: '#abstractTextBlock530887', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 71 </div> </div> <div class="block-bottom-pagination"> <div class="pager-info"> <p>Showing 1 to 10 of 24 Paper Titles</p> </div> <div class="pagination-container"><ul class="pagination"><li class="active"><span>1</span></li><li><a href="/AEF.25/2">2</a></li><li><a href="/AEF.25/3">3</a></li><li class="PagedList-skipToNext"><a href="/AEF.25/2" rel="next">></a></li></ul></div> </div> </div> </div> </div> </div> </div> </div> <div class="social-icon-popup"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-popup-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-popup-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-popup-icon social-icon"></i></a> </div> </div> <div class="sc-footer"> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="footer-menu col-md-12 col-sm-12 col-xs-12"> <ul class="list-inline menu-font"> <li><a href="/ForLibraries">For Libraries</a></li> <li><a href="/ForPublication/Paper">For Publication</a></li> <li><a href="/insights" target="_blank">Insights</a></li> <li><a href="/DocuCenter">Downloads</a></li> <li><a href="/Home/AboutUs">About Us</a></li> <li><a href="/PolicyAndEthics/PublishingPolicies">Policy & Ethics</a></li> <li><a href="/Home/Contacts">Contact Us</a></li> <li><a href="/Home/Imprint">Imprint</a></li> <li><a href="/Home/PrivacyPolicy">Privacy Policy</a></li> <li><a href="/Home/Sitemap">Sitemap</a></li> <li><a href="/Conferences">All Conferences</a></li> <li><a href="/special-issues">All Special Issues</a></li> <li><a href="/news/all">All News</a></li> <li><a href="/open-access-partners">Open Access Partners</a></li> </ul> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-footer-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-footer-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-footer-icon social-icon"></i></a> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12 footer-copyright"> <p> © 2025 Trans Tech Publications Ltd.
