General Purpose Simulation System (GPSS) is a special computer programming language primarily used to simulate what can be classified as discrete systems. A discrete system is one where, at any given instant in time, a countable number of things can take place. The basic operation of a mine itself can be considered such a system. Discrete Simulation and Animation for Mining Engineers explains how to model mining systems using GPSS/H (R) and PROOF (R) by Wolverine Software Corporation. Employing a unique approach that encourages engagement from the start, the text discusses animation first, and then slowly introduces simulation language. As each new topic is covered, an animation is provided to illustrate the key concepts.Leveraging valuable insight gained from the author's extensive experience modeling mines around the world, the book: Describes how to apply discrete system simulation to mines Shows how to make those simulations come alive with animation Includes real-world examples and exercises that hone practical problem-solving skills Written by a mining engineer for mining engineers and students of mining, Discrete Simulation and Animation for Mining Engineers offers a comprehensive yet accessible treatment of mine simulation and animation useful in increasing the efficiency of industrial mining processes.
Many areas of mining engineering gather and use statistical information, provided by observing the actual operation of equipment, their systems, the development of mining works, surface subsidence that accompanies underground mining, displacement of rocks surrounding surface pits and underground drives and longwalls, amongst others. In addition, the actual modern machines used in surface mining are equipped with diagnostic systems that automatically trace all important machine parameters and send this information to the main producer's computer. Such data not only provide information on the technical properties of the machine but they also have a statistical character. Furthermore, all information gathered during stand and lab investigations where parts, assemblies and whole devices are tested in order to prove their usefulness, have a stochastic character. All of these materials need to be developed statistically and, more importantly, based on these results mining engineers must make decisions whether to undertake actions, connected with the further operation of the machines, the further development of the works, etc. For these reasons, knowledge of modern statistics is necessary for mining engineers; not only as to how statistical analysis of data should be conducted and statistical synthesis should be done, but also as to understanding the results obtained and how to use them to make appropriate decisions in relation to the mining operation. This book on statistical analysis and synthesis starts with a short repetition of probability theory and also includes a special section on statistical prediction. The text is illustrated with many examples taken from mining practice; moreover the tables required to conduct statistical inference are included.
The study of fracture mechanics of concrete has developed in recent years to the point where it can be used for assessing the durability of concrete structures and for the development of new concrete materials. The last decade has seen a gradual shift of interest toward fracture studies at increasingly smaller sizes and scales. Concrete Fracture: A Multiscale Approach explores fracture properties of cement and concrete based on their actual material structure. Concrete is a complex hierarchical material, containing material structural elements spanning scales from the nano- to micro- and meso-level. Therefore, multi-scale approaches are essential for a better understanding of mechanical properties and fracture in particular. This volume includes various examples of fracture analyses at the micro- and meso-level. The book presents models accompanied by reliable experiments and explains how these experiments are performed. It also provides numerous examples of test methods and requirements for evaluating quasi-brittle materials. More importantly, it proposes a new modeling approach based on multiscale interaction potential and examines the related experimental challenges facing research engineers and building professionals. The book's comprehensive coverage is poised to encourage new initiatives for overcoming the difficulties encountered when performing fracture experiments on cement at the micro-size/scale and smaller. The author demonstrates how the obtained results can fit into the larger picture of the material science of concrete-particularly the design of new high-performance concrete materials which can be put to good use in the development of efficient and durable structures.
Supplementary cementing materials (SCMs), such as fly ash, slag, silica fume, and natural pozzolans, make a significant difference to the properties of concrete but are rarely understood in any detail. SCMs can influence the mechanical properties of concrete and improve its durability in aggressive environments. Supplementary Cementing Materials in Concrete covers the chemical, physical, and mineralogical properties of SCMs; their chemical reactions; and the resulting changes in the microstructure of concrete. The author links the properties of the material at the microstructural level with its behavior in laboratory tests, and, in turn, to the performance of the material in concrete structures under field exposure. He explains how SCMs influence the mechanical properties of concrete and improve its durability and also covers how various SCMs influence hydration reactions and the evolution of the pore structure and pore-solution composition. However, SCMs are not a panacea for concrete and improper use may be injurious to certain properties. Achieving the maximum benefit from SCMs requires an understanding of the materials and how they impact concrete properties under various conditions. Drawing on the author's 30 years of experience, this book helps engineers and practitioners to optimize the use of supplementary cementing materials to improve concrete performance.
The stability of underground and surface geotechnical structures during and after excavation is of great concern as any kind of instability may result in damage to the environment as well as time-consuming high cost repair work. The forms of instability, their mechanisms and the conditions associated with them must be understood so that correct stabilisation of the structure through rock reinforcement and/or rock support can be undertaken. Rock Reinforcement and Rock Support elucidates the reinforcement functions of rock bolts/rock anchors and support systems consisting of shotcrete, steel ribs and concrete liners and evaluates their reinforcement and supporting effects both qualitatively and quantitatively. It draws on the research activities and practices carried out by the author for more than three decades and has culminated in a most extensive up-to-date and a complete treatise on rock reinforcement and rock support.
The text broadly covers recent developments in ground control techniques, and their at operating mines, worldwide. Specific topics include: design and analysis of support and re-inforcement in metalliferous mines, mesh, shotcrete and membrane support systems, and strata control in coal mines.

Mining can have negative environmental and social impacts, but can also be responsible. However corporations have little impetus to act responsibly without being held to account by an informed and active public, and by strong institutions and governments which not only create but also enforce legislation. Yet what does such practice look like? This book shows how the concept of responsible mining is based on five key principles or pillars: holistic assessment; ethical relationships; community-based agreements; appropriate boundaries and good governance. Together, these pillars circumscribe global best practice and innovative ideas to catalyse new and improved approaches to a sustainable mining industry. The author argues that these practices are critical to the future viability and social acceptability of the global mining industry and draws on a range of case studies, including from Australia, Canada, Central Asia, Papua New Guinea and west Africa. The role of informed communities, governments and civil societies in holding the industry to account to achieve responsible mining is assessed. The book explains how companies judge what effects they may have on communities and investigates ways to improve the prediction and prevention of such impacts and to provide clearer, more meaningful public communication. It offers alternatives to common 'corporate social responsibility' practices in which mining companies adopt roles which are usually the remit of government. Ultimately, it looks to the future, exploring the essential pathways towards responsible mining.
The Deep Mixing Method (DMM), a deep in-situ soil stabilization technique using cement and/or lime as a stabilizing agent, was developed in Japan and in the Nordic countries independently in the 1970s. Numerous research efforts have been made in these areas investigating properties of treated soil, behavior of DMM improved ground under static and dynamic conditions, design methods, and execution techniques. Due to its wide applicability and high improvement effect, the method has become increasingly popular in many countries in Europe, Asia and in the USA. In the past three to four decades, traditional mechanical mixing has been improved to meet changing needs. New types of the technology have also been developed in the last 10 years; e.g. the high pressure injection mixing method and the method that combines mechanical mixing and high pressure injection mixing technologies. The design procedures for the DM methods were standardized across several organizations in Japan and revised several times. Information on these rapid developments will benefit those researchers and practitioners who are involved in ground improvement throughout the world. The book presents the state of the art in Deep Mixing methods, and covers recent technologies, research activities and know-how in machinery, design, construction technology and quality control and assurance. The Deep Mixing Method is a useful reference tool for engineers and researchers involved in DMM technology everywhere, regardless of local soil conditions and variety in applications.
In the seven years since the publication of the first edition of Sustainable Practices in Geoenvironmental Engineering, the combination of population growth and increased exploitation of renewable and non-renewable natural resources has added increased stresses on the quality and health of the geoenvironment. This is especially true when viewed in the context of the growing demand for food and shelter, energy and mineral resources, and their resultant effects on the natural capital of the geoenvironment. Completely revised and updated, this second edition of a bestseller introduces and discusses the concept of "stressors" and their impacts on the geoenvironment. See What's New in the Second Edition: Clear definition of the geoenvironment New tools and remediation technologies, new management methods for geohazards, and enhanced coverage of social and economic sustainability Innovative approaches and techniques for reaching geoenvironmental sustainability More detail on treatment technologies, both in situ and ex situ Discussion on the mitigation of geodisasters Additional sections to discuss sustainability assessment protocols Updated information on models for prediction of contaminant behavior The authors explore the technologies that take into account targets, exposure routes (if applicable), future land use, acceptable risks, legislation, and resultant emissions/discharges in establishing the criteria and tools for evaluating technologies and protocols for environmental management of the impacted land. They then discuss how to choose the correct ones to use in different situations to protect the quality and health of natural resource and capital of the geoenvironment and ensure that these geoenvironmental natural resources and capital remain available for future generations and to develop innovative and sustainable techniques to make land more stable and safer.
The environmental imperative exerts strong pressure on polluting industries in the industrialised countries. Environmentally-friendly technologies are available but often at prohibitive costs. Using evidence from the copper industry, this book addresses the question of how polluting industries in developing and transition economies have responded to this challenge. Technological Change and the Environmental Imperative considers the extent of the success of polluting industries in becoming cost-efficient whilst acquiring less polluting technologies, in the face of fierce competition. The authors also discuss what has been the impact of privatisation on this process and what lessons have been learnt. Against this backdrop, and drawing on case material from Chile, China, Peru and Russia, the book goes on to assess the latest technological breakthroughs, and their possible future impact on cost efficiency and the environment. International organisations, policymakers and industry analysts concerned with environmental issues will find this book of great fascination as will academics and researchers in the fields of development studies, transition economies and environmental studies.
