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 639 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.
Download or read book Mine Design Planning and Sustainable Exploitation in the Digital Age written by A.J.S. (Sam) Spearing and published by CRC Press. This book was released on 2022-09-19 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mine Design, Planning and Sustainable Exploitation in the Digital Age covers mine planning, design and exploitation taking cognizance of new developments, especially those associated with the Fourth Industrial Revolution and the positive influence that it has, and will have, on the mining industry. It refers to latest best practices with emphasis on the social license to operate and sustainable (green) mining. The book covers surface and underground mining in some detail and addresses relevant associated aspects such as risk management, green mining and the importance of real community relations. It is organized as follows: Surface Mining Underground Soft Rock Mining Underground Hard Rock (Metal/Non-metal) Mining Green and Sustainable Mining It has many relevant photos and figures that help the reader and includes appropriate support design and types commonly used in the various mining methods. Mine Design, Planning and Sustainable Exploitation in the Digital Age is mainly aimed at mining, geological engineering and other undergraduate and postgraduates interested in the mining resources industry. It will also serve as a useful reference book for practitioners in the mining industry who want an easy-to-use book.
Download or read book Highwall Mining written by John Loui Porathur and published by CRC Press. This book was released on 2017-07-06 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive technical book on highwall mining covers theory and practice coupled with practical examples and design aspects. It contains eight extensive chapters elaborating broad-spectrum functionalities of highwall mining and its operational aspects, covering world scenario, economic potential, methods of coal extraction, design methodology including empirical web pillar design, numerical modelling for stress analysis, safety factor for web pillars, panel and barrier design, small-and large-scale numerical modelling, multiple seam interaction and design, coal web pillar strength, equivalent width concept, laboratory testing, new web pillar strength formula, effect of weak bands in coal seam, slope stability, safety and ground monitoring, hazards and regulatory requirements, case examples, norms and guidelines for practice. It also summarizes the results of research carried out by the CSIR Central Institute of Mining and Fuel Research (CSIR-CIMFR), India and the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia on the subject. The book will equip readers in understanding the complex, multiple seam scenarios for highwall mining, and its design for maximum coal recovery from any given site with better economics, which will aid the mining companies in extracting locked-up coal following the safety norms to avoid hazards and minimise instability issues. A large number of case studies is included to illustrate the application of numerical modelling for prior estimation and viability of highwall mining operations under varying geomining conditions. The book will be of interest to professionals and academics in the field of mining engineering specifically, but will also interest civil, geomechanical and geological engineers as well as rock mechanics professionals.
