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 Productivity in Natural Resource Industries written by R. David Simpson and published by Routledge. This book was released on 2014-04-04 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several senior natural resource analysts study the role played by innovation, particularly technological innovation, in the pursuit of heightened productivity. Increasing the output of a given input improves a firm‘s bottom line, makes it more competitive internationally, and reduces the potential for resource depletion and shortages. Thus, high productivity is a necessary ingredient of economic prosperity. This book illustrates the importance of technological innovation in achieving an acceptable level of output and efficiency. In this important new offering, a team of resource scholars describes and chronicles the development of recent innovations in selected natural resource industries. The authors also reveal the causes, sources, and net effect of such innovation on productivity. In all of these sectors productivity has increased considerably since the early 1980s, although the level of improvement varies across industries. To what degree did technological innovation contribute to that increase? Individual detailed case studies detail important innovations in America‘s coal, petroleum, copper, and forest industries. The primary focus is on extraction and production technologies, although the existence and importance of innovation in other areas such as management technique also enter the picture. For example, the combination of new technology with restructuring seems to have breathed new life into a floundering U.S. copper industry. The authors describe the origin and diffusion of important innovation, and the concluding chapter quantifies the net effect of such innovation on productivity.

Download or read book Longwall Mining 3rd Edition written by Syd S. Peng and published by CRC Press. This book was released on 2019-10-29 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past 13 years since the publication of Longwall Mining, 2nd edition in 2006, although there have been no major changes in longwall mining technology and operations, many incremental developments in the whole system as well as various subsystems of the existing longwall mining operational technologies as detailed in the 2nd edition have been added to this edition. Major developments are automation, and health and safety technology, as well as equipment reliability, thereby greatly increasing productivity and cutting cost. In particular, the longwall system can now run automatically cut by cut forever without operators' intervention provided that the geology allows it. Other health and safety features such as LASC, personal proximity detection, color lighting, automatic shield water sprays and remote shearer control are fully operational. There are more than 7000 sensors installed in current longwall mining systems. The big data obtained and fast communication technology have been fully utilized to improve and solve operational problems in real time. Those features are fully documented in the new edition. In pursuit of high productivity and cutting cost, life cycle management that increases equipment reliability has been implemented by OEM. Automation improvement such as tail-end automatic chain tensioner greatly extends AFC chain's service life. Other incremental improvements including dust and methane controls, entry development, panel design and face move are addressed. Additional operational issues such as extension of panel width and compatibility test are also discussed. Since the last plow longwall mine was closed in 2018, the chapter on plow longwalling has been dropped and in its place Automation of Longwall Components and System is added. Also, a new chapter Longwall Top Coal Caving Mining (LTCC) is added due to its successful application in Australia since 2005. Longwall Mining, 3rd edition will be of interest to professionals and academics in the field of mining engineering specifically, serving both as a reference work and an (under)graduate textbook, but will also interest civil, geomechanical and geological engineers and rock mechanics professionals, as well as coal operators, mining consultants, researchers, equipment manufacturers, and government regulators.
