Re-imagine the Future of Tailings Nearly every recent article on tailings starts by mentioning a large tailings dam failure. The consequences of these failures have been so devastating they have pushed conversations about the risks inherent in these structures beyond the mining community into the general population. We are left to question how we address the risks associated with tailings disposal, and in so doing, transform the image of the mining industry and perhaps the industry itself. With this as a backdrop, the Society for Mining, Metallurgy & Exploration (SME) challenged tailings and mining professionals to re-imagine the future of tailings. The Mine Tailings: Perspectives for a Changing World symposium, held at the SME 2020 annual conference, started that conversation. Over three days, tailings professionals from around the world gathered to discuss tailings storage practices and the changes both the industry and the world want and need. The discussions squarely focused on how we, as an industry, can collectively make changes that will eliminate catastrophic tailings dam failures and lead to better outcomes for the industry and society. Through sharing and conversation, the symposium participants recognized risks associated with our approach to tailings management and existing structures and discussed the gaps that need to be addressed, including how the behavior of tailings and mining professionals must change. The human element of risk must be recognized so it can be talked about openly, given the attention it deserves, and adequately addressed. We need to own this problem and the impact of our actions. We have the power to change this; when we own our actions, we can act differently for a different outcome.

Since the start of colonial gold mining in the early 1920s, the Biangai villagers of Elauru and Winima in Papua New Guinea have moved away from planting yams and other subsistence foods to instead cultivating coffee and other cash crops and dishing for tradable flakes of gold. Decades of industrial gold mining, land development, conservation efforts, and biological research have wrought transformations in the landscape and entwined traditional Biangai gardening practices with Western capital, disrupting the relationship between place and person and the social reproduction of a community. Drawing from extensive ethnographic research, Jamon Halvaksz examines the role of place in informing indigenous relationships with conservation and development. How do Biangai make meaning with the physical world? Collapsing Western distinctions between self and an earthly other, Halvaksz shows us it is a sense of place-grounded in productive relationships between nature and culture-that connects Biangai to one another as "placepersons" and enables them to navigate global forces amid changing local and regional economies. Centering local responses along the frontiers of resource extraction, Gardens of Gold contributes to our understanding of how neoliberal economic practices intervene in place-based economies and identities.

How literature of the British imperial world contended with the social and environmental consequences of industrial mining The 1830s to the 1930s saw the rise of large-scale industrial mining in the British imperial world. Elizabeth Carolyn Miller examines how literature of this era reckoned with a new vision of civilization where humans are dependent on finite, nonrenewable stores of earthly resources, and traces how the threatening horizon of resource exhaustion worked its way into narrative form. Britain was the first nation to transition to industry based on fossil fuels, which put its novelists and other writers in the remarkable position of mediating the emergence of extraction-based life. Miller looks at works like Hard Times, The Mill on the Floss, and Sons and Lovers, showing how the provincial realist novel's longstanding reliance on marriage and inheritance plots transforms against the backdrop of exhaustion to withhold the promise of reproductive futurity. She explores how adventure stories like Treasure Island and Heart of Darkness reorient fictional space toward the resource frontier. And she shows how utopian and fantasy works like "Sultana's Dream," The Time Machine, and The Hobbit offer imaginative ways of envisioning energy beyond extractivism. This illuminating book reveals how an era marked by violent mineral resource rushes gave rise to literary forms and genres that extend extractivism as a mode of environmental understanding.

Since the beginning of the US shale gas revolution in 2005, the development of unconventional oil and gas resources has gathered tremendous pace around the world. This book provides a comprehensive overview of the key geologic, geophysical, and engineering principles that govern the development of unconventional reservoirs. The book begins with a detailed characterization of unconventional reservoir rocks: their composition and microstructure, mechanical properties, and the processes controlling fault slip and fluid flow. A discussion of geomechanical principles follows, including the state of stress, pore pressure, and the importance of fractures and faults. After reviewing the fundamentals of horizontal drilling, multi-stage hydraulic fracturing, and stimulation of slip on pre-existing faults, the key factors impacting hydrocarbon production are explored. The final chapters cover environmental impacts and how to mitigate hazards associated with induced seismicity. This text provides an essential overview for students, researchers, and industry professionals interested in unconventional reservoirs.

"Uncovers a centuries-long story of obsession that often included murder, gun fights, deadly accidents, overnight fortunes and even cannibalism. . . Neligh is a practiced writer whose style mixes history and modern realities seamlessly." -Colorado Country Life Gold! brings together the story of this metal’s glittering legacy in the Centennial State and the madness, murder, and mayhem that came along with it. The book examines the rich history of the miners and treasure hunters who came to face danger and hardships in the unforgiving Rocky Mountains. This story is unique in that it takes a look at the phenomenon of gold, the treasure hunters, both modern and historic, and brings them to life in a detailed and sharp narrative. Author Ian Neligh spent a year meeting with experts and enthusiasts, hearing their stories and trying to understand why it is they continue to do what they do—often in the face of extreme hardship. Modern-day gold miners profiled include Al Mosch, Bill Chapman, Ken Reid, and Chad Watkins. Gold! is the story of an unusual subculture on the rise in the mountains of Colorado fueled by a delicate balance of hope, greed, and loss. It tells the story of men mostly forgotten by the world as they go in endless pursuit of an impossible fortune. It follows miners working their small, dangerous gold claims in mines over a hundred years old, to modern-day prospectors trying to strike it rich and counterbalance the weight of a struggling economy. The book also examines if those who spend their lives in search of riches—ever actually strike it rich. From the author of Spurred West: Rogues, Treasure Seekers, Bounty Hunters, and Colorful Characters Past and Present, this book will appeal to both history buffs as well as fans of modern-day reality shows like Gold Rush.

This volume provides an international forum for the exchange of the latest and most up-to-date designs for multiphase flow. The development for marginal offshore oil and gas discoveries and/or land-based fields in remote locations have led to significant research aimed at improving our understanding of this complex technology. Better design methods have been developed, not only for transporting multiphase hydrocarbon fluids over long distances, but also for pumping, metering, and processing equipment. Pressure on minimising costs and need to develop smaller, deeper, and more remote fields have continued to spur the application of multiphase technology. However, the uncertainty of adopting new technology will only be overcome with knowledge and expertise, by field use, or by force of circumstances, where it is seen to be the only viable method. From research to products, this book brings together contributions from experts who shape the way the technology is developed. Topics covered include: flow modelling; oil-water flow modelling; slug modelling; field applications in multiphase modelling; multiphase metering; multiphase equipment; flow assurance. This work provides the reader with the opportunity to determine how and when the technology can and should be employed in the filed, the engineer must understand what the technology can actually achieve, its limitations, and how these are being mitigated or overcome.

The total environment in which mining takes place is the result of many physical, regional and circumstantial conditions. This is a 1986 text which deals with the assessment and control of these conditions, providing a source of ready reference for engineers and advanced students studying the mining environment. With the need for greater economy in the extraction of minerals, the search for deposits of minerals, increasing mining legislation and pressure from environmental groups, the study of mining engineering is becoming increasingly important. This book relates the mining environment to both the efficiency and safety of the production process, and to the physiological and psychological effects on personnel and the public. Each element of the environment - gas, dust, radiation, heat, water and noise - is considered in relation to its accompanying hazards, its sources, detection, and control measures, resulting in a detailed text for the study of the design, operation and maintenance of mines.

Details the proper methods to assess, prevent, and reduce corrosion in the oil industry using today's most advanced technologies This book discusses upstream operations, with an emphasis on production, and pipelines, which are closely tied to upstream operations. It also examines protective coatings, alloy selection, chemical treatments, and cathodic protection--the main means of corrosion control. The strength and hardness levels of metals is also discussed, as this affects the resistance of metals to hydrogen embrittlement, a major concern for high-strength steels and some other alloys. It is intended for use by personnel with limited backgrounds in chemistry, metallurgy, and corrosion and will give them a general understanding of how and why corrosion occurs and the practical approaches to how the effects of corrosion can be mitigated. Metallurgy and Corrosion Control in Oil and Gas Production, Second Edition updates the original chapters while including a new case studies chapter. Beginning with an introduction to oilfield metallurgy and corrosion control, the book provides in-depth coverage of the field with chapters on: chemistry of corrosion; corrosive environments; materials; forms of corrosion; corrosion control; inspection, monitoring, and testing; and oilfield equipment. Covers all aspects of upstream oil and gas production from downhole drilling to pipelines and tanker terminal operations Offers an introduction to corrosion for entry-level corrosion control specialists Contains detailed photographs to illustrate descriptions in the text Metallurgy and Corrosion Control in Oil and Gas Production, Second Edition is an excellent book for engineers and related professionals in the oil and gas production industries. It will also be an asset to the entry-level corrosion control professional who may have a theoretical background in metallurgy, chemistry, or a related field, but who needs to understand the practical limitations of large-scale industrial operations associated with oil and gas production.

This book addresses the practice of geostatistical simulation to evaluation of mineral reserves, prediction of recovered tonnages and mineral grades and the impact of mining dilution. Such prediction is absolutely critical for mine planning and investment decisions, yet it cannot be made on maps directly interpolated from present data. Various dilution factors need to be introduced to account for - the support effect: mining unit volumes are vastly different from composite data unit volumes - the information effect: future selection of ore/waste will be based on vastly different data than that presently available. Geostatistical simulations allow a rigorous evaluation of these effects on reserves recovery. These stochastic simulations have the potential to be for the mining industry what a wind tunnel is for aircraft design. This book is written by two expert geostatisticians--Journel is the pioneer of mining geostatistics--and established academics.
