Available in PDF, EPUB and Kindle. Book excerpt: Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.

Download or read book Guidelines for Open Pit Slope Design written by John Read and published by CSIRO PUBLISHING. This book was released on 2009-11-09 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Guidelines for Open Pit Slope Design is a comprehensive account of the open pit slope design process. Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on rock slope stability in open pit mines, this book provides an up-to-date compendium of knowledge of the slope design processes that should be followed and the tools that are available to aid slope design practitioners. This book links innovative mining geomechanics research into the strength of closely jointed rock masses with the most recent advances in numerical modelling, creating more effective ways for predicting rock slope stability and reliability in open pit mines. It sets out the key elements of slope design, the required levels of effort and the acceptance criteria that are needed to satisfy best practice with respect to pit slope investigation, design, implementation and performance monitoring. Guidelines for Open Pit Slope Design comprises 14 chapters that directly follow the life of mine sequence from project commencement through to closure. It includes: information on gathering all of the field data that is required to create a 3D model of the geotechnical conditions at a mine site; how data is collated and used to design the walls of the open pit; how the design is implemented; up-to-date procedures for wall control and performance assessment, including limits blasting, scaling, slope support and slope monitoring; and how formal risk management procedures can be applied to each stage of the process. This book will assist in meeting stakeholder requirements for pit slopes that are stable, in regards to safety, ore recovery and financial return, for the required life of the mine.

Download or read book Coal Waste Impoundments written by National Research Council and published by National Academies Press. This book was released on 2002-01-07 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: On October 11, 2000, a breakthrough of Martin County Coal Corporation's coal waste impoundment released 250 million gallons of slurry in near Inez, Kentucky. The 72-acre surface impoundment for coal processing waste materials broke through into a nearby underground coal mine. Although the spill caused no loss of human life, environmental damage was significant, and local water supplies were disrupted. This incident prompted Congress to request the National Research Council to examine ways to reduce the potential for similar accidents in the future. This book covers the engineering practices and standards for coal waste impoundments and ways to evaluate, improve, and monitor them; the accuracy of mine maps and ways to improve surveying and mapping of mines; and alternative technologies for coal slurry disposal and utilization. The book contains advice for multiple audiences, including the Mine Safety and Health Administration, the Office of Surface Mining, and other federal agencies; state and local policymakers and regulators; the coal industry and its consultants; and scientists and engineers.

Download or read book Stability Analysis in Room and Pillar Coal Mining written by Richard Wright and published by . This book was released on 1981 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research presented in this study is primarily concerned with the application of numerical modelling techniques to the stability analysis of coal mine structures. The work has been limited to room and pillar coal mining of flat and gently dipping (below 20°) seams. Conventional analytic techniques are described, together with numerical and physical modelling techniques that are presently available. The boundary element computer program (DDSEAMS) which has been used in this analysis is described in detail, and the results of limited testing of the program are included. A stress analysis design concept is presented, which includes the development of a stress criterion for stability at a point. Comparisons are made between the numerical model, a 3-D physical model, a base friction model and an underground phenomenological study at Grande Cache, Alberta. An illustration of the stress analysis design concept is included, with reference to a proposed mine at Coal Valley, Alberta. This includes a detailed geotechnical testing program, and the analysis of a number of alternative mine geometries. The major conclusions are: * Improved stress analysis, compared to conventional methods, are obtained by using the numerical model presented. * Definition of a stress criterion is useful for the prediction of over-stressed regions that are potentially unstable. * Where strata stress conditions or pillar safety factors indicate that failure will take place, the use of elastic analysis techniques is not adequate for the definition of the overall stability. * The 3-D physical modelling qualitatively simulates pillar failures observed in the underground phenomenological study at Grande Cache * Initial analysis indicates that extraction ratios greater than 50% may be possible by the "punch" mining method proposed at Coal Valley.
