Shotcrete: Elements of a System by Stefan Bernard Pdf
Over the last twenty years we have witnessed a revolution in ground stabilization in both underground and above-ground applications, thanks largely to the widespread adoption of shotcrete as a medium for support. Shotcrete technology continues to evolve and improve as its utilization increases. From relatively obscure and sporadic beginnings, it has now become central to ground stabilization in mines and tunnels throughout advanced nations in the world, and is increasingly being used in developing nations. The reasons for this success are clear. Shotcrete offers unrivaled scope for adaptation to varying ground conditions when used for stabilization, and allows flexibility with respect to geometry when used in other applications. The absence of form work and the fact that it conforms to irregular substrates helps to reduce costs, and it can be installed very rapidly. In many situations shotcrete will prove the most economical means of stabilization or construction, and it is more durable than most alternatives. The combination of these factors has made shotcrete the material of first choice in most underground support applications and in an increasing number of above-ground applications. As utilization spreads, new and innovative approaches to construction with this material continue to arise. The engineering basis for analysis and design of shotcrete linings and structures has also improved. This volume includes a selection of papers describing recent developments in the evolving field of shotcrete technology, written by a wide range of authors from around the world. The subjects range from mining-related ground control requirements, testing and performance characterization, and durability, to nozzleman education and accreditation requirements. The result is a reference providing a useful compendium of recent developments which should appeal to shotcrete technologists and practitioners alike.
Sprayed concrete lined (SCL) tunnels are growing rapidly in popularity due to their versatility. The design and construction of both hard rock and soft ground tunnels has been revolutionised by the advent of the SCL method and now the use of permanent sprayed concrete linings has unlocked the true potential of the method to minimise construction costs and times. Yet the complex early age behaviour of the sprayed concrete makes the design difficult and requires a robust management system during construction. Consequently the great advantages of the method must be balanced against the risks, as a few high-profile tunnel collapses have illustrated. Practising engineers on site, in the design office or in client organizations will find this book an excellent introduction. It covers all aspects of SCL tunnelling – from the constituents of sprayed concrete to detailed design and management during construction. Although there is a close interdependence between all the facets of sprayed concrete, few engineers have the right breadth of experience and expertise to cover all of them. This urgently needs to be transferred to the wider engineering community as SCL tunnels play an increasingly important role in the delivery of the underground infrastructure which modern urban life demands. In this second edition, beyond a general updating to reflect new developments, the sections on permanent sprayed concrete, the innovative technology of spray applied waterproofing membranes, fibre reinforcement (both steel and macrosynthetic) and composite lining design have been expanded. Sustainability and environmental impact are addressed in a new section.
SME Mining Engineering Handbook, Third Edition by Peter Darling,Society for Mining, Metallurgy, and Exploration (U.S.) Pdf
This third edition of the SME Mining Engineering Handbook reaffirms its international reputation as "the handbook of choice" for today's practicing mining engineer. It distills the body of knowledge that characterizes mining engineering as a disciplinary field and has subsequently helped to inspire and inform generations of mining professionals.Virtually all of the information is original content, representing the latest information from more than 250 internationally recognized mining industry experts. Within the handbook's 115 thought-provoking chapters are current topics relevant to today's mining professional: Analyzing how the mining and minerals industry will develop over the medium and long term--why such changes are inevitable, what this will mean in terms of challenges, and how they could be managed Explaining the mechanics associated with the multifaceted world of mine and mineral economics, from the decisions associated with how best to finance a single piece of high-value equipment to the long-term cash-flow issues associated with mine planning at a mature operation Describing the recent and ongoing technical initiatives and engineering developments in relation to robotics, automation, acid rock drainage, block caving optimization, or process dewatering methods Examining in detail the methods and equipment available to achieve efficient, predictable, and safe rock breaking, whether employing a tunnel boring machine for development work, mineral extraction using a mobile miner, or cast blasting at a surface coal operation Identifying the salient points that dictate which is the safest, most efficient, and most versatile extraction method to employ, as well as describing in detail how each alternative is engineered Discussing the impacts that social and environmental issues have on mining from the pre-exploration phase to end-of-mine issues and beyond, and how to manage these two increasingly important factors to the benefit of both the mining companies and other stakeholders
Tunnels and Underground Cities: Engineering and Innovation Meet Archaeology, Architecture and Art by Daniele Peila,Giulia Viggiani,Tarcisio Celestino Pdf
Tunnels and Underground Cities: Engineering and Innovation meet Archaeology, Architecture and Art. Volume 6: Innovation in underground engineering, materials and equipment - Part 2 contains the contributions presented in the eponymous Technical Session during the World Tunnel Congress 2019 (Naples, Italy, 3-9 May 2019). The use of underground space is continuing to grow, due to global urbanization, public demand for efficient transportation, and energy saving, production and distribution. The growing need for space at ground level, along with its continuous value increase and the challenges of energy saving and achieving sustainable development objectives, demand greater and better use of the underground space to ensure that it supports sustainable, resilient and more liveable cities. The contributions cover a wide range of topics, from artificial intelligence techniques for geomechanical forecasting, via fiber reinforced concrete segmental lining, to advanced 4-channel scan systems for tunnel inspection. The book is a valuable reference text for tunnelling specialists, owners, engineers, archaeologists, architects, artists and others involved in underground planning, design and building around the world, and for academics who are interested in underground constructions and geotechnics.
Shotcrete: Materials, Performance and Use is a comprehensive textbook covering the current state-of-the-art shotcrete technology. It provides an overview of the many and various uses of shotcrete. Shotcrete is well suited for construction of curvilinear structures (domes, shells, bobsleigh/luge tracks, etc.) and overhead shotcrete applications (seismic retrofit, repairs, ground support, etc.) that could not be constructed technically and/or economically using conventional formed, cast-in-place concrete construction methods. It contains chapters on history, shotcrete materials and mixture proportioning, performance, shotcrete research, equipment and shotcrete application. It is also comprised of shotcrete case history examples including buildings and structures, infrastructure repair and rehabilitation, ground support and shoring, underground support in tunnels and mines, swimming pools and spas, and, finally, architectural shotcrete. This text should be of interest to design engineers and architects considering the use of the technology, as well as academics. It serves as a useful guide to contractors using shotcrete in one or more of its many and various applications.
