This book was released on 1978 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stowing (backfilling) is not practiced in United States coal mines, although it is extensively used in underground coal mines in other countries and in many underground metal mines. The objectives of stowing in active coal mines may be to reduce surface subsidence, to permit higher recovery with adequate safety, to control spontaneous combustion, to extinguish fires, or to reduce mine acid drainage. An associated objective of stowing may be to dispose of mine wastes underground, and thereby to minimize the environmental impacts of surface disposal. This report surveys the state of foreign technology for stowing, based primarily on developments in Europe and the USSR. Two Russian books and many papers were translated to English from Russian, Polish, and German. The conditions for potential application of stowing in the U.S. are identified and the research and development needs are outlined which may in the future make stowing economically viable in underground U.S. coal mines despite the present strong objections by the coal mine industry. A demonstration program is recommended for pneumatic stowing in a longwall coal mine, as well as a feasibility study for stowing in room-and-pillar mines.

Available in PDF, EPUB and Kindle. Book excerpt: "This book summarizes many years of research, domestic and foreign experience in the application of hydraulic stowing to the underground mining of coal. Problems of the theory, practice and engineering design of processes of hydraulic stowing are analyzed. Classifications are presented of existing stowing installations, methods of selection of stowage materials, elements of efficient technology and automation of hydraulic stowing are described, as are new programmed technological systems of hydraulic stowing equipment and methods for economic evaluation of stowing and determination of areas of its application. The book is intended for engineering and technical workers employed by mining enterprises, scientific research and planning-design institutes"--p. 1.
