Conditions of Suitability of Coal Seams for Underground Coal Gasification

Results of evaluating the suitability of certain sections of Western Donbas coal seams, based predominately on properties of coal material, for their further experimental development by means of underground gasification method are represented. Criteria to evaluate both expediency of underground gasification and specific conditions of that process are substantiated basing upon the methodology developed at the National Mining University (Dnipro, Ukraine) together with representatives from National University of Saint Augustine (Arequipa, Peru). The methodology has been industrially approved with the confirmation of its efficiency while developing technical documentation for underground gasification projects: “Project of experimental section of Pidzemgaz station of Pavlogradvuhillia association”, “Feasibility study of the expediency of the construction of Pidzemgaz station” FS 3858-PZ”, Synelnykovo deposit; “Project on experimental underground gas generator”, Monastyryshche deposit, FS of experimental module of UCG station of Solenovske coal-mining area, Donbas. Also, they contain the researches, which were conducted within the project GP – 489, financed by Ministry of Education and Science of Ukraine.

Power consumption of rock decomposition process during diamond core drilling using pulse flushing

The present study was based on the results of the experimental research into the process of diamond core drilling in pulse flushing mode within the frames of projects implemented by the Department of Deposits Prospecting Technique at the National Mining University (Dnipro University of Technology, Dnipro, Ukraine). The authors hereby express their gratitude to all colleagues at the Department of Deposits Prospecting Technique who took part in the experimental research.

Selecting the method of gas hydrate deposits development in terms of the regularities of their formation

The work is performed at the National Mining University in the Underground Mining Department, in accordance with the Law of Ukraine “On priority directions of science and technology” from 12.10.2010 No.2519-17, within the framework of the Integrated Program “Development of methods and technologies for extracting gas from natural gas hydrates and creation of artificial hydrates to optimize production processes” (GP-467, GP-473), under the supervision of Professor Volodymyr Bondarenko, to whom the author expresses deep gratitude for the constant and comprehensive support.

Computational model for evaluating the state of geomechanical systems during computing experiments

This work would not have been possible without the support of “DTEK Energo” company. The studies were performed within the framework of the state-maintained scientific research topics. The authors express special gratitude to professors of the National Mining University – Volodymyr Bondarenko and Iryna Kovalevska – for the support in conducting the research.

Cutting-edge industrial technology of mining tool manufacturing

Scientific work is done in the framework of complex special purpose program “Organizing collection, utilization and recycling processes of hard alloys containing tungsten, tungsten scrap, molybdenum, cobalt and their alloys”. The authors extend their thanks to Rostyslav Didyk, Professor with the Department of Mining Engineering of the National Mining University.

Technological complex for production, transportation and storage of gas from the offshore gas and gas hydrates fields

This work has become possible due to financial and organizational support within the frames of the state budget research project under the auspices of the Ministry of Education and Science of Ukraine “Application of gas hydrate technology in the development of traditional and gas hydrate gas deposits” No 0113U00857, “Research of influence of thermodynamic parameters of phase transitions in systems with gas hydrates on the efficiency of gas hydrate technology” No 0115U002420. The authors express their gratitude to the supervisor of these projects – Doctor of Sciences, Professor, Head of the Underground Mining Department at the National Mining University (Dnipropetrovsk) Volodymyr Bondarenko for his support in conducting the research.

Estimation of corrosion resistance of curing mixtures based on coal-bearing rocks from Western Donbass

The authors express their gratitude to the administration of the Department of Construction, Geotechnics and Geomechanics of the National Mining University (Dnipropetrovsk, Ukraine), represented by O. Shashenko and A. Solodiankin, as well as to all those who helped in carrying out works related to preparation of this paper.

SPECIFIC FEATURES OF COMPETENT-BASED APPROACH INTRODUCTION IN FOREIGN LANGUAGE TEACHING/LEARNING PROCESS IN NON-LINGUISTIC HIGHER EDUCATIONAL ESTABLISHMENTS OF UKRAINE

The purpose of the article is to study specific features of introducing competence-based approach in the process of teaching and learning foreign languages under current conditions. The results are obtained with the following research methods: experimental research and empirical methods, while researching modern concepts in foreign language education and creating our own understanding of communicative language competence and its components, standard methods of survey used in social research for gathering qualitative and quantitative data, while studying current situation in foreign language education and evaluating the results of introducing changes from the perspective of the stakeholders involved (feedback, interviewing, observations are included). The main characteristics and principles of competence-based approach to language teaching being introduced in non-linguistic higher educational establishments are examined. Its pros and cons as well as the positive experience of its implementing in the National Mining University (Dnipropetrovsk, Ukraine) are analysed. Special attention is drawn to changes in the role of teachers and students in education and the English-speaking classroom in particular. The results of changes triggered by introduction of competence-based approach are analysed and evaluated taking into consideration the information from various sources and a case study for the National Mining University. Data analysis proves evidence of positive changes in foreign language education in the Ukrainian universities, and introduction of modern approaches to teaching/learning languages focused on learning process. Recommendations are given on how to improve foreign language education by introducing e-learning in teaching/learning process.

International student mobility as a factor of the European integration of Ukrainian youth

The report focuses on the role of the international mobility of Ukrainian students in the process of shaping their worldview values and the gradual inclusion in the European educational and cultural context. The participation of Ukrainian students in the internationalisation of higher education is analyzed on the example of the National Mining University. The report examines the impact of the learning experience of the Ukrainian students abroad to inculcate in them a more active approach to life, intercultural skills and European values, awareness of themselves as part of a common European cultural space.
