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.

Book excerpt: A method of gasification of coal in deep, thin seams by using controlled bending subsidence to confine gas flow to a region close to the unconsumed coal face. The injection point is moved sequentially around the perimeter of a coal removal area from a production well to sweep out the area to cause the controlled bending subsidence. The injection holes are drilled vertically into the coal seam through the overburden or horizontally into the seam from an exposed coal face. The method is particularly applicable to deep, thin seams found in the eastern United States and at abandoned strip mines where thin seams were surface mined into a hillside or down a modest dip until the overburden became too thick for further mining.

This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report defines the state of the art (circa 1978) in removing thin coal seams associated with vastly thicker seams found in the surface coal mines of the western United States. New techniques are evaluated and an innovative method and machine is proposed. Western states resource recovery regulations are addressed and representative mining operations are examined. Thin seam recovery is investigated through its effect on (1) overburden removal, (2) conventional seam extraction methods, and (3) innovative techniques. Equations and graphs are used to accommodate the variable stratigraphic positions in the mining sequence on which thin seams occur. Industrial concern and agency regulations provided the impetus for this study of total resource recovery. The results are a compendium of thin seam removal methods and costs. The work explains how the mining industry recovers thin coal seams in western surface mines where extremely thick seams naturally hold the most attention. It explains what new developments imply and where to look for new improvements and their probable adaptability.
