Geomechanics is the mechanics of geomaterials, i.e. soils and rocks, and deals with fascinating problems such as settlements, stability of excavations, tunnels and offshore platforms, landslides, earthquakes and liquefaction. This edited book presents recent mathematical and computational tools and models to describe and simulate such problems in geomechanics and geotechnical engineering. It includes a collection of contributions emanating from the three Euroconferences GeoMath ('Mathematical Methods in Geomechanics') that were held between 2000 and 2002 in Innsbruck/Austria and Horto/Greece.

The first edition of this book demystified the process of well log analysis for students, researchers and practitioners. In the two decades since, the industry has changed enormously: technical staffs are smaller, and hydrocarbons are harder to locate, quantify, and produce. New drilling techniques have engendered new measurement devices incorporated into the drilling string. Corporate restructuring and the "graying" of the workforce have caused a scarcity in technical competence involved in the search and exploitation of petroleum. The updated 2nd Edition reviews logging measurement technology developed in the last twenty years, and expands the petrophysical applications of the measurements.

This contributed volume presents a multi-perspective collection of the latest research findings on oil and gas exploration and imparts insight that can greatly assist in understanding field behavior, design of test programs, and design of field operations. With this book, engineers also gain a powerful guide to the most commonly used numerical simulation methods that aid in reservoir modelling. In addition, the contributors explore development of technologies that allow for cost effective oil and gas exploration while minimizing the impact on our water resources, surface and groundwater aquifers, geological stability of impacted areas, air quality, and infrastructure assets such as roads, pipelines, water, and wastewater networks. Easy to understand, the book identifies equipment and procedural problems inherent to oil and gas operations and provides systematic approaches for solving them.

The present book is the outcome of an Advanced Study Institute meeting, which was held in Kallithea, Chalkidiki, in Northern Greece, from 12-25 May 1991 and attended by 69 delegates from 18 countries. The Institute brought together scientists, engineers and technologists currently involved in basic and applied research on the different aspects of flotation. The Institute covered subjects in four major areas of flotation: a) fundamentals; b) chemical technology aspects; c) mineral processing; and d) water and wastewater treatment. Apart from the papers reproduced in this volume, several short oral communications were also presented. Participants also had the opportunity to visit the Hellenic Chemical Products & Fertilizers Co. Ltd. mixed sulphides plant, in Chalkidiki. Conference participants, whose interest and research projects are in this broad field of science and engineering, provided a well-informed discussion of the problems encountered, as well as possible directions of future technological developments. It is hoped that this book is not only a good record of the presentations made (formal and informal), analyzing the state-of-the-art in flotation, but will also be helpful for students, scientists and technologists working in the fields of separation processes and in particular mineral processing and wastewater engineering. All the invited speakers and the participants made this summer school possible, worthwhile and enjoyable. The sponsorship by the NATO Scientific Affairs Division is gratefully ack nowledged. The Editors would like to thank the members of the Organizing Committee, Dr. B.A."

New trends in mineral deposits mining largely consist of intensifying and concentrating mining operations. Innovative technologies helping to increase technical-economic indices, extraction volume, working efficiency and safety rules are presented in this book.

A guide for students and professionals, this introductory course book covers the basic principles of remote sensing and its applications in mine environment monitoring. Building from a reader's basic knowledge of mine monitoring, it teaches how to implement remote sensing techniques and how to interpret the acquired data for different purposes. Following a general introduction to remote sensing principles and image analysis, mine subsidence monitoring, slope stability monitoring, reclamation planning and implementation, and post-closure mine and land use analysis are explained and illustrated. With the help of case studies, the techniques and tools presented are demonstrated. With an increasing importance of sustainable mining, this accurate text is intended for the education of university students in mining, civil, geological and environmental engineering. Researchers and professionals in these disciplines may find it beneficial as well to guide their professional monitoring investigations.

Provides a description of the thermodynamic model, data treatment procedures and the thermodynamic constants for hydrous ferric oxide. Includes detailed coverage of the model and the parameter extraction procedure.

In the years following the publication of Magnetic Methods for the Treatment of Minerals by Elsevier in 1987, many changes have taken place in magnetic technology. While fundamental and thorough, the above treatise re?ected pr- erences and philosophy of research and the development and application of magnetic methods as they were practiced in the second half of the last c- tury. Although demand for metals and minerals has not diminished, the d- inant drivers of the early 21st century di er signi?cantly from those of the late 20th. The priorities of nuclear power, defence, and energy-demanding and waste-generating bene?ciation of mineral resources are being replaced by those associated with technology sustainability, environmental and knowledge m- agement, recycling, and health care. Research priorities and product devel- ment of the last century cannot, therefore, satisfactorily meet criteria of the 21st century. Considerable technological progress has been achieved in areas such as - tomation, computerization, sustainable material science, laboratory and plant practices and separation equipment. New permanent magnetic materials, - vances in practical applications of superconductivity and availability of soph- ticated modelling tools have changed the technological landscape. As a result, innovation and technology transfer in magnetic technology have been rema- ably successful during the last two decades. The title of this monograph re?ects the fact that the book covers not only the application of magnetic techniques in the minerals industry, but also in recycling, environmental engineering and biomedical sciences.

Nowhere is the conflict between economic progress and environmental quality more apparent than in the mineral extraction industries. The latter half of the 20th century saw major advances in the reclamation technologies. However, mine water pollution problems have not been addressed. In many cases, polluted mine water long outlives the life of the mining operation. As the true cost of long-term water treatment responsibilities has become apparent, interest has grown in the technologies that would decrease the production of contaminated water and make its treatment less costly. This is the first book to address the mine water issue head-on. The authors explain the complexities of mine water pollution by reviewing the hydrogeological context of its formation, and provide an up-to-date presentation of prevention and treatment technologies. The book will be a valuable reference for all professionals who encounter polluted mine water on a regular or occasional basis.

The proceedings in this work present 60 papers on mine and mill tailings and mine waste, as well as current and future issues facing the mining and environmental communities. This includes matters dealing with technical capabilities and developments, regulations, and environmental concerns.

The proceedings of the 6th International Symposium on Mining in the Arctic, held in Greenland in 2001. The papers cover a wide variety of topics, including: mining exploration and exploitation; mining engineering and mine design; environmental impact of mining in the Arctic; and more.

This text covers the use of computer applications in the mineral industries, encompassing topics such as the use of computer visualization in mining systems and aspects such as ventilation and safety.

The safe and economical construction of tunnels, mines, and other subterranean works depends on the correct choice of support systems to ensure that the excavations are stable. These support systems should be matched to the characterstics of the rock mass and the excavation techniques adopted. Establishing the support requirements, designing support systems and installing these correctly are essential elements in safe underground construction. This is a comprehensive and practical work which also gives access to user-friendly computer programmes which enable the investigation and design of support techniques. Details on how to obtain this software are also included in the book.
