Presenting new technologies in underground coal extraction, with special attention to mine galleries support and maintenance, load mechanism of "massif-support system-safety system" systems, analysis of face equipment for thin coal seams mining and substantiation of rational stoping parameters.
Advanced surface mining technologies of coal and ore are discussed in an original form, stability calculations of internal dumps and open-cut faces are presented, as well as examination of land surface subsidence using modern methods of calculation experiments. Special attention is given to the complex mining of mineral resources, such as: iron ore, coal deposits with drilling advance degassing wells, methane extraction from coal and anthropogenic deposits, heat receipt from mine water with help of thermal pumps.
The unique geological conditions for mining in Poland and the Ukraine require a new technological approach for mining thin and very thin coal seams with thickness of 1 meter and less, using selective coal extraction methods, leaving rock behind in the mine. Relevant technological solutions are discussed in this volume.
Further, technological process control during coal seams underground gasification is described together with pressure-temperature conditions of gas hydrates formation from gaseous mixtures of various content. Substantiation is also given to gas hydrates extraction technologies development and 21st century new pulse technologies of well drilling and a temperature mode of a rock-cutting tool and equipment with cryogenic-gravel filters is examined.
Gas extraction processes located in flooded deposits with uniform and macroheterogeneous collectors are presented with the description of an effective methodology of two-subbench technology of ore deposits extraction.

He is a chairman of the methodological committee of higher education standards preparation of the Ministry of Education and Science of the Ukraine for his speciality Mining. Volodymyr Bondarenko is one of the authors of Development strategies of coal industry of Ukraine until 2030 as part of a single work Strategy of energy development of Ukraine until 2030 and founder of the International School of Underground Mining that consolidates its efforts on saving and development of new scientific trends. The School's format - holding annual International scientific and practical conferences with presence of well-known specialists-miners of Ukraine, Russia, Poland, Germany and other countries. 20 candidate dissertations and 6 doctoral dissertations have been defended under the direction of Volodymyr Bondarenko, who is author of 245 scientific works, including 15 textbooks, tutorials and monographs, 37 patents for invention have been gained, 33 scientific articles have been printed abroad in famous publications of Germany, England, USA, Canada, Poland and Russia. Iryna Kovalevska (1968) graduated from the department of Mechanics, mechanical-mathematical faculty of Dnipropetrovsk's state university in 1990. She is a mechanic, applied mathematics specialist.She took a post-graduate course at the Institution of Geotechnical Mechanics of the Ukraine named after M.S. Polyakov, defended dissertations of technical sciences candidate and doctor of technical sciences, and finally became professor of Underground Mining Department of theNational Mining University. I.A. Kovalevska is doctor of technical sciences and has been awarded the third degree Miner's Glory award, she is author of 25 monographs, guided two candidates of technical sciences, and two specialized councils defending candidate and doctoral dissertations. Finally, she is head of budget and economic research areas.? Kostiantyn Ganushevych is Research Assistant and PhD student at the Underground Mining Department. His research is on gas hydrates studies and extraction technologies. He is author of 11 papers and 3 patents, has been a participant in 3 international mining conferences. He is a member of the organizing committee of the international conference School of Underground Mining, which is held in Crimea, Ukraine. Currently he is engaged in two scientific-research projects focused on gas hydrates extraction technologies development for the conditions of the Black Sea and financed by the Ukrainian government. Dr Ganushevych delivers lectures related to underground mining technologies for advanced students in English.
