Rock Mechanics and Rock Engineering is concerned with the application of the principles of mechanics to physical, chemical and electro-magnetic processes in the upper-most layers of the earth and the design and construction of the rock structures associated with civil engineering and exploitation or extraction of natural resources in mining and petroleum engineering. Rock mechanics requires profound knowledge of rock-constituting elements, discontinuities and their behavior under various physical and chemical actions in nature. The governing equations together with constitutive laws and experimental techniques and the solution techniques are explained and some examples of applications are given. The applications of rock mechanics to engineering structures in/on rock, rock excavation techniques and in-situ monitoring techniques are explained and some specific examples are given. The dynamic aspects associated with the science of earthquakes and their effect on rock structures, and the characteristics of vibrations induced by machinery, blasting and impacts as well as measuring techniques are described. Furthermore, the degradation and maintenance processes in rock engineering are explained. Some chapters are devoted to possible new directions in rock mechanics. This two-volume set is intended to be a fundamental resource for younger generations and newcomers and a reference work for experts specialized in Rock Mechanics and Rock Engineering and associated with the fields of mining, civil and petroleum engineering, engineering geology, and/or specialized in Geophysics and concerned with earthquake science and engineering.

Sorption technique was employed to remove heavy metals from gold mining effluent using natural and plant materials for sustainability. An assessment of the effluent quality of a gold mining company in Ghana indicated that arsenic, copper and cyanide were the major pollutants in the process effluent. Arsenic and copper were successfully removed from the effluent by the studied materials. The research showed that the down-flow fixed-bed treatment configuration is an ideal system for the simultaneous removal of copper and arsenic from low concentration gold mining effluent, in addition to other heavy metals present in very low concentrations.

In the last decades coal production capacity has increased rapidly and its quality, power and the reliability of equipment has steadily improved. Moreover, stability of production processes can be controlled better. In connection with that, unification of scientific schools focusing on "Mining of deposits" is an integral trend from the viewpoint of technical and technological policy.

This collection of papers represents the scientific and technical achievements with regard to mineral deposits mining intensification based on effective use of modern techniques and technologies. Also, specific attention is paid to progressive and innovational technologies in the coal industry of leading countries.

Widening the range of mining-geological conditions under which drivage and maintenance of mining activities are carried out, requires application of new constructive decisions. Hence, this collection of papers is focusing on the following topics: results of new equipment introduction; experiments on mutual interaction of roof support elements, protective construction and near-the-contour rock massif; analytical and calculation methods of geomechanical tasks solution; development of gas hydrates and technologies of underground coal gasification; studies on environment protection; economic aspects; management and marketing in mining production, and other important aspects of mineral deposits exploitation.

This book focuses on agglomeration, or the size enlargement process, of iron ores. This process sits at the interface of mineral processing and extractive metallurgy. The book begins with a discussion of raw materials preparation and the beneficiation process. It then describes fundamental principles of the sintering and pelletization processes, including formation of green mix through granulation and green balls as well as chemical reactions during sintering. Finally, it offers a brief description of iron making processes and correlations related to the agglomerates: quality parameters and BF productivity and coke rate.

Negotiated agreements play a critical role in setting the conditions under which resource development occurs on Indigenous land. Our understanding of what determines the outcomes of negotiations between Indigenous peoples and commercial interests is very limited. With over two decades experience with Indigenous organisations and communities, Ciaran O'Faircheallaigh's book offers the first systematic analysis of agreement outcomes and the factors that shape them, based on evaluative criteria developed especially for this study; on an analysis of 45 negotiations between Aboriginal peoples and mining companies across all of Australia's major resource-producing regions; and on detailed case studies of four negotiations in Australia and Canada.

Aluminium was one of most cartelised industries in the international economic panorama of the 20th century. Born following the discovery of electrolytic smelting process in 1886, this industry, even in its infancy, established a cartel which characterised its history until nearly 1980. Managers of the aluminium industry from various historical eras and countries shared the same vision about the development of their industry: to keep prices as stable as possible in order to encourage expansions and to provide return on investments. Price instability, which characterised the trade of other commodities, was unknown to the aluminium industry. This book neither argues that cartels are fundamentally evil, nor attempts to demonstrate that cartels are optimal business organisations. It instead provides an in-depth and frank analysis of the internal working of industrial organisations and of the interplay between cartels and political powers and institutions. The International Aluminium Cartel offers explanations for the construction and collapse of cartels, descriptions of their operations, and an historical interpretation of their experiences. Incorporating information gleaned from a unique collection of private and public archives from several countries, this unique study will appeal to a wide variety of readers, including academics interested in industrial and business history.

An Ideal Source for Geologists and Others with Little Background in Engineering or Mechanics Practical Rock Mechanics provides an introduction for graduate students as well as a reference guide for practicing engineering geologists and geotechnical engineers. The book considers fundamental geological processes that give rise to the nature of rock masses and control their mechanical behavior. Stresses in the earth's crust are discussed and methods of measurement and prediction explained. Ways to investigate, describe, test, and characterize rocks in the laboratory and at project scale are reviewed. The application of rock mechanics principles to the design of engineering structures including tunnels, foundations, and slopes is addressed. The book is illustrated throughout with simple figures and photographs, and important concepts are illustrated by modern case examples. Mathematical equations are kept to the minimum necessary and are explained fully-the book leans towards practice rather than theory.This text: Addresses the principles of rock mechanics as it applies to both structural geology and engineering practice Demonstrates the importance of and methods of geological characterisation to rock engineering Examines the standard methods of rock mechanics testing and measurement as well as interpretation of data in practice Explains connections between main parameters both empirically as well as on the basis of scientific theory Provides examples of the practice of rock mechanics to major engineering projects Practical Rock Mechanics teaches from first principles and aids readers' understanding of the concepts of stress and stress transformation and the practical application of rock mechanics theory. This text can help ensure that ground models and designs are correct, realistic, and produced cost-effectively.

Artisanal mining is commonly associated with violent conflict, rampant corruption and desperate poverty. Yet millions of people across Sub Sahara Africa depend on it. Many of them are living in eastern Democratic Republic of Congo (DRC), home to important mineral reserves, but also to a plethora of armed groups and massive human rights violations. African Artisanal Mining from the Inside Out provides a rich and in-depth analysis of the Congolese gold sector. Instead of portraying miners and traders as passive victims of economic forces, regional conflicts or disheartening national policies, it focuses on how they gain access to and benefit from gold. It shows a professional artisanal mining sector governed by a set of specific norms, offering ample opportunities for flexible employment and local livelihood support and being well-connected to the local economy and society. It argues for the viability of artisanal gold mining in the context of weak African states and in the transition towards a post-conflict and more industrialized economy. This book will be of great interest to researchers and postgraduates studying natural resources and development as well as those in development studies, African studies, sociology, political economy, political ecology, legal pluralism, and history.

The extractive sector is a particular area of expertise for Canada and more than half of Canada's mining assets abroad are located in Latin America, specifically in Brazil, Peru, Chile, and Colombia. The Canada-Colombia accord was the first free-trade agreement in the world to include annual Human Rights Impact Assessments (HRIA), and also includes a labour side accord where abuse complaints can be formally registered. Using Colombia as a case study, James Rochlin and his international and multidisciplinary line up of Canadian and Colombian scholars, and activists working in the area of human rights, and the judiciary explore: What is the best way to identify and operationalize for mutual benefit the concentric space between the interests of extractive corporations in profit and security, on the one hand, and the interests of the host communities in the promotion of human rights and human security, on the other? What can the four emblematic and diverse cases in Colombia (Meta, Sergovia, Marmato, and Bolivar/La Guajira) tell us about how to fine tune and improve a newly implemented governmental HRIA to render it an increasingly useful global instrument to promote simultaneously corporate security and human security for host communities? What is the most efficient and effective way to design and implement Corporate Social Responsibility Programs in a manner that promotes simultaneously corporate security and community human security? Written in a clear and accessible style, Profits, Security, and Human Rights presents practical lessons on how to promote both corporate security and human security in communities where the extractive sector operates in the Global South.

This overview of the analysis and design of buildings runs from basic principles and elementary structural analysis to the selection of structural systems and materials, and on to foundations and retaining structures. It presents a variety of approaches and methodologies while featuring realistic design examples. As a comprehensive guide and desk reference for practicing structural and civil engineers, and for engineering students, it draws on the author's teaching experience at The City College of New York and his work as a design engineer and architect. It is especially useful for those taking the National Council of Examiners for Engineering and Surveying SE exam.

After more than three decades of economic malaise, many African countries are experiencing an upsurge in their economic fortunes linked to the booming international market for minerals. Spurred by the shrinking viability of peasant agriculture, rural dwellers have been engaged in a massive search for alternative livelihoods, one of the most lucrative being artisanal mining. While a burgeoning literature is acknowledging the spread of artisanal mining, this book is the first to probe its societal impact and potential for extending economic opportunity and participatory forms of democracy. Delineating the paradoxes of artisanal miners working alongside the expansion of large-scale mining investment in Africa, Mining and Social Transformation in Africa concentrates on the Tanzanian experience. Written by authors with fresh research insights, focus is placed on how artisanal mining is configured in relation to local, regional and national mining investments and social class differentiation. The work lives and associated lifestyles of miners and residents of mining settlements are brought to the fore, asking where this historical interlude is taking them and their communities in the future. The question of value transfers out of the artisanal mining sector, value capture by elites and changing configurations of gender, age and class differentiation, all arise.

Michael Amundson presents a detailed analysis of the four mining communities at the hub of the twentieth-century uranium booms: Moab, Utah; Grants, New Mexico; Uravan, Colorado; and Jeffrey City, Wyoming. He follows the ups and downs of these 'Yellowcake Towns' from uranium's origins as the crucial element in atomic bombs and the 1950s boom to its use in nuclear power plants, the Three Mile Island accident, and the 1980s bust. Yellowcake Towns provides a look at the supply side of the Atomic Age and serves as an important contribution to the growing bibliography of atomic history.

Indigenous peoples have historically gained little from large-scale resource development on their traditional lands, and have suffered from its negative impacts on their cultures, economies and societies. During recent decades indigenous groups and their allies have fought hard to change this situation: in some cases by opposing development entirely; in many others by seeking a fundamental change in the distribution of benefits and costs from resource exploitation. In doing so they have utilised a range of approaches, including efforts to win greater recognition of indigenous rights in international fora; pressure for passage of national and state or provincial legislation recognising indigenous land rights and protecting indigenous culture; litigation in national and international courts; and direct political action aimed at governments and developers, often in alliance with non-governmental organisations (NGOs). At the same time, and partly in response to these initiatives, many of the corporations that undertake large-scale resource exploitation have sought to address concerns regarding the impact of their activities on indigenous peoples by adopting what are generally referred to as "corporate social responsibility" (CSR) policies. This book focuses on such corporate initiatives. It does not treat them in isolation, recognising that their adoption and impact is contextual, and is related both to the wider social and political framework in which they occur and to the activities and initiatives of indigenous peoples. It does not treat them uncritically, recognising that they may in some cases consist of little more than exercises in public relations. However, neither does it approach them cynically, recognising the possibility that, even if CSR policies and activities reflect hard-headed business decisions, and indeed perhaps particularly if they do so, they can generate significant benefits for indigenous peoples if appropriate accountability mechanisms are in place. In undertaking an in-depth analysis of CSR and indigenous peoples in the extractive industries, the book seeks to answer the following questions. What is the nature and extent of CSR initiatives in the extractive industries and how should they be understood? What motivates companies to pursue CSR policies and activities? How do specific political, social and legal contexts shape corporate behaviour? What is the relationship between indigenous political action and CSR? How and to what extent can corporations be held accountable for their policies and actions? Can CSR help bring about a fundamental change in the distribution of benefits and costs from large-scale resource exploitation and, if so, under what conditions can this occur? Earth Matters gathers key experts from around the world who discuss corporate initiatives in Alaska, Ecuador, Australia, Canada, Peru, Papua New Guinea, Indonesia and Russia. The book explores the great diversity that characterises initiatives and policies under the name of "corporate social responsibility", the highly contingent and contextual nature of corporate responses to indigenous demands, and the complex and evolving nature of indigenous-corporate relations. It also reveals much about the conditions under which CSR can contribute to a redistribution of benefits and costs from large-scale resource development. Earth Matters will be essential reading for those working in and studying the extractive industry worldwide, as well as those readers looking for a state-of-the-art description of how CSR is functioning in perhaps its most difficult setting.

Emotions in the workplace have until recently been seen simply as a distraction. We often think of work as rational, logical and non-emotional. But organisations are waking up to the key role of emotions and affect at work. Emotions influence how we make decisions, how we relate with one another and how we make sense of our surroundings. Whilst organisations are slowly embracing the pivotal role of emotions, designers and managers of workplaces have been struggling to keep up. New insights from hard sciences such as neuropsychology are presenting a radically different interpretation of emotions. Yet workplace designers and facilities managers still rely on measuring non-specific states such as satisfaction and stress. In this book we attempt to capture modern-day interpretations of emotion, looking at emotion in terms of transactions and processes rather than simple cause and effect. We entertain the idea of an 'emotionally intelligent building' as an alternative to the much-hyped intelligent building. The assertion is that we should create environments that are emotionally intelligent. Rather than focusing on the aptitudes or shortcomings of individuals at work, we should place closer attention on the office environment. It's not that we are emotionally disabled - it's the environment that disables us! The ability of you and me to interpret, control and express emotions may not simply be a result of our own make-up. A radically different outlook considers how our workspace and workplace debilitates or enables our emotional understanding. In the modern workplace there are many innovations that can undermine our emotional intelligence, such poorly implemented hot-desking or lean environments. Contrariwise there are key innovations such as Activity Based Working (ABW) that have the potential to enhance our emotional state. Through a series of unique case studies from around the world, we investigate key concepts that can be used by designers and facilities managers alike. No longer should designers be asked to incorporate emotional elements as intangible un-costed 'add-ons'. This book provides a shot in the arm for workplace design professionals, pointing to a new way of thinking based on the emotional intelligence of the workplace.

Following an introductory overview of many of the issues of current concern to the field, the book deals with a wide variety of topics, ranging from the environmental impact of gold mining in the Brazilian Amazon, through the issues relevant to coal mining, vegetative and other remediation strategies and procedures and water pollution, to a thorough analysis of environmental management and policy initiatives. The issues raised in Mining and its Environmental Impact may point the way to future solutions to the economic, technological and environmental problems associated with mining in all its aspects and make this volume key reading for practitioners and researchers in the field, as well as for environmentalists generally.

APCOM is a peer-reviewed forum for industrial and research communities working in the mineral industry to share expertise on the application of computer and operations research technology. Recognized since the 1960s as the worlda (TM)s premier conference in the field, APCOM features an impressive range of topics from geostatistics to data warehousing. APCOM 2005 builds on this reputation, showcasing the latest industrial applications and emerging technologies, focusing particularly on mobilizing the inherent value in largely under-used data and information systems, and how these data systems cab be analyzed for real-time or process-based improvements.

This book is a summary of the main restoration works carried out at the Church of the Nativity in Bethlehem that commenced in September 2013. Work on roof wooden structures, wall and floor mosaics, internal plasters, wooden architraves and painted columns of the naves, external wall surfaces and Narthex is all presented in a sequence of reports that accompany the reader up to the final interventions through accurate descriptions of historical and archaeological features, initial state of conservation and appropriate techniques of conservation and restoration. Topics are treated with the methodological and linguistic rigor specific to each disciplinary sector involved even if, in the interest of making reading and comprehension easier, it was sometimes preferred to present only significant case studies, which are nevertheless representative of groups of wider and more complex problems. Through the reading of this work, the reader can simply fulfil his desire for knowledge and obtain answers to certain curiosities about the past history of the Church. At the same time, useful guidelines in dealing with conservation and restoration interventions at historic-architectural sites of similar complexity can be found. The book is, therefore, addressed to a generic reader, interested in the history and conservation of one of the most representative examples of our heritage, but also, in light of its technical and scientific value, to university students, technicians, restorers, architects, structural engineers, archaeologists and historians.

This book is about geoplasticity, solid mechanics of rock, jointed rock and soil beyond the domain of a purely elastic deformation. Plastic deformation is irreversible and begins at the limit to elasticity with any attempt at further loading. Stress at the limit to elasticity is "strength" which is described by a functional relationship amongst stresses, that is, by a yield function or failure criterion. Mohr-Coulomb, Drucker-Prager and Hoek-Brown criteria are well-known examples in geomechanics. Beyond the elastic limit, but still within the realm of small strain increments, a total strain increment is the sum of an elastic increment and a plastic increment. The elastic increment is computed through an incremental form of Hooke's law, isotropic or anisotropic as the case may be. Computation of the plastic part is at the core of any plasticity theory and is approached through the concept of a plastic potential. The plastic potential is a function of stresses and perhaps other material parameters such as plastic strain and temperature. Derivatives of the plastic potential with respect to stress lead to the plastic part of the total strain increment. If the yield criterion and plastic potential are the same, then the plastic stress-strain relationships are "associated rules of flow" and follow a "normality" principle. Normality is in reference to a graphical portrayal in principal stress space where the plastic strain increment is perpendicular to the yield surface. If the plastic potential and yield criterion are different, as is often the case in geoplasticity, then the rules of flow are "non-associated". Drucker's famous stability postulate implies normality at a smooth point on the yield surface, convexity of the yield function and other important features of plasticity theory in geomechanics. However, there is no point to proceeding to theoretical analyses without physical justification. Hence, the physical foundations for application of plasticity theory to rock, jointed rock and soil are examined in Chapter 2 of this book. A brief review of continuum mechanics principles is given in Chapter 3. Chapter 4 focuses on plane plastic strain and "sliplines". The technical literature is replete with numerous diagrams of sliplines, especially in discussions of foundations on soils, but the relevant mathematics is often lacking and with it genuine understanding. Examples illustrate application of theory to traditional geomechanics problems such as computation of retaining wall forces in soils, foundation bearing capacity of soil and rock, wedge penetration of rock under confining pressure and others. Brief discussions of anisotropy, visco-plasticity and poro-plasticity are presented in Chapters 6, 7 and 8. This book will be of interest to civil, geological and mining engineers, particularly those involved in reliable design of excavations and foundations beyond elasticity, especially in jointed rock.

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.

For over 80 years, the National Society of Professional Engineers (NSPE) has been a leader in the promotion of ethical practice within the field of engineering. One of the Society's greatest contributions is the formation and adoption of the NSPE Code of Ethics. But the code, with its six "Fundamental Canons," is only truly instructive if engineers can bridge the gap between principles and action. Here there is no substitute for personal reflection on the ethical and philosophical issues that underlie the code. If done well, such reflection provides an indispensable basis for moral problem solving. Beyond the Code: A Philosophical Guide to Engineering Ethics is designed to complement the NSPE Code of Ethics by helping readers "go beyond" in their understanding of the philosophical issues bound up in the code. Each chapter addresses one of the Fundamental Canons of the NSPE code, and provides a philosophical analysis of the various parts of each canon by employing contemporary and classical texts. This unique approach to engineering ethics guides students and professionals in their readings of the appended selections to refine their understanding of the code in order to apply it to the practical challenges of today's engineers. Key Features: Is the first introduction to engineering ethics that helps students understand and apply the NSPE Code of Ethics to engineering practice Includes a Preface from Arthur E. Schwartz, NSPE Deputy Executive Director and General Counsel, and NAFE Executive Director As a hybrid text, includes primary philosophical texts with extensive introductions and guided reading questions from the book's three authors Offers case studies from the NSPE Board of Ethical Review, allowing students to see a direct connection between the issues discussed in the text and real-world engineering practice Includes the following pedagogical aids: "Key Terms and Concepts" for each chapter "Preparing to Read" sections before each primary source reading "Guided Reading Questions" after each primary source reading "Going Beyond-Our Questions for a Deep Dive" after each case study.

In There Used to Be Order, Patience Mususa considers social change in the Copperbelt region of Zambia following the re-privatization of the large state mining conglomerate, the Zambia Consolidated Copper Mines (ZCCM), in the mid-1990s. As the copper mines were Zambia's most important economic asset, the sale of ZCCM was considered a major loss to the country. More crucially, privatization marked the end of a way of life for mine employees and mining communities. Based on three years of ethnographic field research, this book examines life for those living in difficult economic circumstances, and considers the tension between the life they live and the nature of an 'extractive area.' This account, unusual in its examination of middle-income decline in Africa, directs us to think of the Copperbelt not only as an extractive locale for copper whose activities are affected by the market, but also as a place where the residents' engagement with the harsh reality of losing jobs and struggling to earn a living after the withdrawal of welfare is simultaneously changing both the material and social character of the place. Drawing on phenomenological approaches, the book develops a theoretical model of 'trying,' which accounts for both Copperbelt residents' aspirations and efforts.

For most of the twentieth century tin was fundamental for both warfare and welfare. The importance of tin is most powerfully represented by the tin can - an invention which created a revolution in food preservation and helped feed both the armies of the great powers and the masses of the new urban society. The trouble with tin was that economically viable deposits of the metal could only be found in a few regions of the world, predominantly in the southern hemisphere, while the main centers of consumption were in the industrialized north. The tin trade was therefore a highly politically charged economy in which states and private enterprise competed and cooperated to assert control over deposits, smelters and markets. Tin provides a particularly telling illustration of how the interactions of business and governments shape the evolution of the global economic trade; the tin industry has experienced extensive state intervention during times of war, encompasses intense competition and cartelization, and has seen industry centers both thrive and fail in the wake of decolonization. The history of the international tin industry reveals the complex interactions and interdependencies between local actors and international networks, decolonization and globalization, as well as government foreign policies and entrepreneurial tactics. By highlighting the global struggles for control and the constantly shifting economic, geographical and political constellations within one specific industry, this collection of essays brings the state back into business history, and the firm into the history of international relations.

More than half of the world's petroleum is to be found in carbonate rocks, for example in the Middle East, the former USSR and in North America. These rocks show a bewildering diversity of grains and textures, due in part to the wealth of different fossil organisms which have contributed to carbonate sedimentation, and in part to a wide variety of diagenetic processes which can radically modify textures and obscure the depositional fabric.Careful petrographic study with a polarising microscope is a key element of any study of carbonate sediments, as a companion to field or core logging, and as a necessary precursor to geochemical analysis. This atlas, which illustrates in full colour a range of features not attempted in any general textbook, is designed as a laboratory manual to keep beside the microscope, as an aid to identifying grain types and textures in carbonates. It appeals alike to undergraduate and graduate students and to professionals in teaching institutions, research laboratories and industry.
