This book was released on 2014-08-11 with total page 536 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2011-12-16 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides an up-to-date overview of the Polish and international experience in the area of thin coal seam mining with an emphasis on implementation of the plow technology in mining. The implementation of the plow technology in Poland is performed by young engineers for whom the automated extraction system presents itself as a great challenge showing the direction of future developments: a production mining face manned by a skeleton crew, fully utilizing the potential offered by the information technology. They create new ways and means of running the production processes, which are successfully used together with the new generation plows. Successive generations of young mining engineers entering their careers are equipped with a new type of ability and, most of all, awareness which is characterized by a new understanding of reality, in which "real" is what is on the screen. They are the guarantee that this direction of research and the drive towards minimizing human involvement in the underground production chores will receive increasing focus and will remain the area of development. The experiences to-date of three mines (KWK Zofiówka, KWK Jas-Mos, and LW Bogdanka SA) show that there is a real potential for the Polish companies to join in the research aimed at developing new plow installations.

Available in PDF, EPUB and Kindle. Book excerpt: Studies have estimated that 156 billion tons of coal, representing two-thirfs of the minable reserves in the Untied States, are subject to multiple-seam mining. In some U.S. coalfields, particularly in central Appalachia and the West, the majority of today's mine are operating above and/or beneath previously mined seams.
