Rock salt formations have long been recognized as a valuable resource - not only for salt mining but for construction of oil and gas storage caverns and for isolation of radioactive and other hazardous wastes. Current interest is fast expanding towards construction and re-use of solution-mined caverns for storage of renewable energy in the form of hydrogen, compressed air and other gases. Evaluating the long term performance and safety of such systems demands an understanding of the coupled mechanical behavior and transport properties of salt. This volume presents a collection of 60 research papers defining the state-of-the-art in the field. Topics range from fundamental work on deformation mechanisms and damage of rock salt to compaction of engineered salt backfill. The latest constitutive models are applied in computational studies addressing the evolution and integrity of storage caverns, repositories, salt mines and entire salt formations, while field studies document ground truth at multiple scales. The volume is structured into seven themes: Microphysical processes and creep models Laboratory testing Geological isolation systems and geotechnical barriers Analytical and numerical modelling Monitoring and site-specific studies Cavern and borehole abandonment and integrity Energy storage in salt caverns The Mechanical Behavior of Salt X will appeal to graduate students, academics, engineers and professionals working in the fields of salt mechanics, salt mining and geological storage of energy and wastes, but also to researchers in rock physics in general.

This book aims to present an alternative based on natural processes and an environmental approach to post-excavation site management, e.g., post-coal mining heaps. These sites are places where various mineral excavation by-products are collected. Nevertheless, some post-mineral excavation sites are oligotrophic, terrestrial, wetland, and water habitat islands, providing unique biodiversity enrichment in the landscape. These oligotrophic mineral habitats are essential in over-fertilized, eutrophic, agricultural and urban-industry surroundings. Some post-mineral excavation sites are places where the wildlife can develop and support the functional processes of novel ecosystems. Implementing the newest biogeochemical and comprehensive knowledge into urban-industry landscape management will help to establish the ecosystem's processes and environmental functioning. There are several post-industrial sites in Europe where the wildlife areas developed due to natural processes, are becoming wildlife hotspots in densely populated urban-industry areas. In this respect, many of the oligotrophic mineral terrestrial, wetland, and water habitats of anthropogenic origin should not be categorized as environmentally dangerous and undergo economic utility-focused reclamation. Facing the actual environmental constraints of the Anthropocene Epoch, the book's chapters presenting the natural basics and perquisites of the environmental ecosystem mosaics, will be interesting for a broad range of environmentalists (scientists and students), miners, economists, and sociologists.

Emerald-green hiddenite, a gem so valuable that it is said "a June bug can carry away $1,000 worth," is only found in one area of North America: Alexander County, North Carolina. Now known as the village of Hiddenite, the area has continuously produced gems of great beauty since 1875, including the largest natural emerald and the largest faceted emerald in North America. The beauty of the area's free-standing minerals of emerald green beryl and spodumene, as well as amethyst, smoky quartz, calcite, and rutile have attracted collectors, adventurers, and miners since their discovery. The search for emeralds and other gemstones over more than 100 years has generated true drama: controversies about mineral names, who discovered what, tragic fatal accidents, and physical strife between individuals. This book reveals the whole story. Alongside the fascinating history of the area, it includes detailed information about the geology of the region, and will be of interest to the historian, mineral enthusiast, and the curious reader alike.

This book uses a multimethod approach to examine local experience of contemporary mining development in the Peruvian Andes, creating an understanding of the transformations that rural societies experience in this context. Mining is a major component of economic growth in many resource endowed countries, whilst also causing mixed social, cultural, and environmental effects. Most current literature on contemporary mining in Peru is largely focussed on conflict; however, in this text, the author takes a differing approach by examining the experiences of families in the vicinity of Rio Tinto's La Granja exploration copper project, Northern Peru, an area with great significance due to the mining investment and development, which has taken place over the past 25 years. The book first provides a critical discussion about production of space theories, and debates on spatial mobility, highlighting their relevance to understanding large-scale mining developments, especially in the Peruvian Andes. The following chapters analyze spatial transformations mining development has prompted, focusing on four axes: access to space, production, mobility, and representations of space. A comprehensive narrative is constructed drawing on diverse voices and perspectives, including those of family heads and their partners, local leaders, company employees, and social scientists. The book concludes by discussing how the findings challenge some of the current accounts of the social effects of mining developement on rural communities and pose significant implications for sustainable development programs and place-based practices. By taking an interdisciplinary approach, this book will appeal to a wide audience including geographers, social anthropologists, and social scientists interested in the social effects of mining as well as researchers interested in current Latin American Studies and Rural Development.

"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. This book will appeal to both history buffs as well as fans of modern-day reality shows like Gold Rush.

Mining activities may result in rock mass deterioration and instability that may lead to failure both in underground and open pit mines. Such deterioration represents a safety risk and may result in substantial financial losses. Rock mass response may lead to ground subsidence, fall of ground/caving, inundation, pillar collapse, seismic activities and slope and tailings dam instability. Each response is preceded by warning signs and precursors, which are identified in this book, with a view to providing guidelines for prediction and amelioration of damage to mining structures. Furthermore, case studies of both large scale ground deterioration leading to collapse and geotechnical mine disasters are presented. Identifying risks and monitoring geotechnical precursors and warning signs allows for safe and productive mining.

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.

The main theme of the book is problematic issues of subsoil use, whereby the contributions are divided in two main parts: - Exploration, mining and processing, and - Mining services Paying much attention to complex processes in the mining industry, Scientific and practical studies of raw material issues will be of interest to academics and professional involved or interested in Mining Engineering and Earth Sciences.

The book comprises two parts: Pressure and Flow Well Testing (Part I) and Temperature Well Testing (Part II), and contains numerous authors' developments. Due to the similarity in Darcy's and Fourier's laws the same differential diffusivity equation describes the transient flow of incompressible fluid in porous medium and heat conduction in solids. Therefore it is reasonable to assume that the techniques and data processing procedures of pressure well tests can be applied to temperature well tests. The book presents new methods to determine the formation of permeability and skin factors from tests conducted in simulated wells, designing interference well tests, processing constant bottom-hole pressure tests, estimation of the formation temperature and geothermal gradients from temperature surveys and logs, in-situ determination of the formation thermal conductivity and contact thermal resistance of boreholes, temperature regime of boreholes (cementing of production liners), and the recovery of thermal equilibrium in deep and superdeep wells. Processing and analysis of pressure and geothermal data are shown on numerous field examples from different regions of the world. The book is intended for students, engineers, and researchers in the field of hydrocarbon geophysics and geology, groundwater searching and exploitation, and subsurface environment examination. It will be also useful for specialists studying pressure and temperature in parametric deep and superdeep wells.
