Available in PDF, EPUB and Kindle. Book excerpt: Parameters related to rockbursts, specifically types of ore, mining operation, magnitude-frequency statistics, maximum magnitudes, depths, and presence of precursory phenomena, are compiled for various tectonic/geologic regions. Data from Canada, the United States, Great Britain, Sweden, West Germany, Poland, Czechoslovakia, South Africa, the USSR, China, Japan, and Australia are tabulated and sorted according to type of geologic conditions. Similarities and differences in source characteristics between rockbursts and natural crustal earthquakes are examined and classified. Type I rockbursts are directly related to an advancing mine face; Type II events involve induced movement along preexisting fault planes. Reliability of prediction of the maximum size of rockbursts based upon mine area, excavation rate, geology, and extent of fracturing of adjacent rock is assessed with special focus on consistency between different areas of the world. The number of Type I rockbursts is found to be a direct function of excavation rate; their locations are consistently determined by location of the mine face and by local geological structure. When Type I events results in new fracture planes, high stress drops result. It is possible that an inactive fault can be activated by the presence of a mine, resulting in Type II rockbursts. Search for reliable precursory phenomena has been unsuccessful. The upper limit for Type I events seems to be controlled by the strength of the rock, whereas the upper limit for Type II events is a completely open question at this time.

Book excerpt: Rockburst: Mechanisms, Monitoring, Warning and Mitigation invites the most relevant researchers and practitioners worldwide to discuss the rock mechanics phenomenon related to increased stress and energy levels in intact rock introduced by drilling, explosion, blasting and other activities. When critical energy levels are reached, rockbursts can occur causing human and material losses in mining and tunneling environments. This book is the most comprehensive information source in English to cover rockbursts. Comprised of four main parts, the book covers in detail the theoretical concepts related to rockbursts, and introduces the current computational modeling techniques and laboratory tests available. The second part is devoted to case studies in mining (coal and metal) and tunneling environments worldwide. The third part covers the most recent advances in measurement and monitoring. Special focus is given to the interpretation of signals and reliability of systems. The following part addresses warning and risk mitigation through the proposition of a single risk assessment index and a comprehensive warning index to portray the stress status of the rock and a successful case study. The final part of the book discusses mitigation including best practices for distressing and efficiently supporting rock. Designed to provide the most comprehensive coverage, the book will provide practicing mining and tunneling engineers the theoretical background needed to better cope with the phenomenon, practical advice from case studies and practical mitigation actions and techniques. Academics in rock mechanics will appreciate this complete reference to rockburst, which features how to analyze stress signals and use computational modeling more efficiently. - Offers understanding of the fundamental theoretical concepts of rockbursts - Explores how to analyze signals from current monitoring systems - Shows how to apply mitigating techniques in current work - Identifies characteristics that should be measured in order to detect rockburst risk

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The perturbation of the earth by mankind causes earthquakes in a variety of situations. This phenomenon continues to be a major concern to engineers and scientists concerned with the mitigation of the consequences of this seismicity, as well as better understanding the processes at its origin. The present volume contains twelve papers from six countries, dealing with observations of triggered and induced seismicity in four continents. The reported cases include seismicity due to hard-rock mines, coal mines, underground research facilities for nuclear waste disposal, water injections, reservoirs, acquifers and oil fields. This volume provides case studies of previously unavailable observations of this phenomenon, investigations of the cause and source mechanism of seismic events, studies of source location distributions, determinations of seismic source parameters, cases of the use of such parameters in assessing rockburst hazard in mines, and measurements of velocity an attenuation properties of rock masses. The present collection of papers provides an excellent indication of the current state of the art and new developments in this area of research.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 843 pages. Available in PDF, EPUB and Kindle. Book excerpt: An international treaty banning the testing of any nuclear device in any environment - a comprehensive test ban treaty (CTBT) - has been on the political agenda for nearly 40 years. Objections to a CTBT have been political, technical, or a combination of both. However, the possibilities seem better after the end of the Cold War. In the prevailing, cooperative disarmament climate a CTBT appears likely to be approved by most countries in 1996. Hence the great current interest in monitoring technologies and capabilities. Such issues are comprehensively addressed here, a preamble being devoted to the political developments and setbacks over the past 40 years. Since seismic means are considered the dominant monitoring element, they are explored in detail. Contributions cover network deployments, advanced signal processing, wave propagation in heterogeneous media, and seismic source representations, and a variety of techniques for source classification (including neural networks). Complementary monitoring techniques, such as hydroacoustics, radionuclides and infrasound, are also summarised. The IAEA operation for monitoring compliance with the Non-Proliferation Treaty is also presented. The book also includes eyewitness accounts of the Soviet 50 Mt megabomb development and test, as well as the efforts made by the state to monitor the nuclear test programmes of the western powers. Includes some 33 articles written by distinguished scientists active in CTBT monitoring research for decades.

Available in PDF, EPUB and Kindle. Book excerpt: There are few books and long review articles on water reservoir induced seismicity, mining induced seismicity and even on volcanic seismicity but the subjects of induced seismicity following fluid extraction and nuclear explosion and seismicity associated with tidal stress in Earth have not received significant attention though there are research papers in relevant literature. Thus an attempt has been made to discuss all the known forms of induced seismicity in the present book and to bring out common features of the different phenomena causing induced seismicity. The book has six main chapters namely 2, 3, 4, 5, 6 and 7, the first and last chapters, namely 1 and 8 being introduction and overview of all forms of induced seismicity. Material in Chapters 2 and 3 is rather recent though water reservoirs and petroleum extraction processes have been in existence over many decades. But, literature on chapters 4 and 5 is available since last one century or so as volcanic process and mining operation affect nearby human habitation and mining severely due to induced seismicity associated with mining in particular. However, literature on possible induced seismicity due to tidal stress is fairly old, the same following nuclear explosion is naturally recent.
