Download or read book Seismic Monitoring in Mines written by A.J. Mendecki and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Routine seismic monitoring in mines was introduced over 30 years ago with two main objectives in mind: • immediate location of larger seIsmIC events to guide rescue operations; • prediction of large rockmass instabilities. The first objective was achieved fairly quickly, but with the subsequent development of mine communication systems, its strategic importance has diminished. The very limited success with prediction can, at least partially, be attributed to three factors: • seismic monitoring systems based on analogue technology that provided noisy and, frequently, poorly calibrated data of limited dynamic range; • the non-quantitative description of a seismic event by at best its local magnitude; and • the resultant non-quantitative analysis of seismicity, frequently through parameters of some statistical distributions, with a somewhat loose but imaginative physical interpretation. The introduction of modern digital seismic systems to mines and progress in the theory and methods of quantitative seismology have enabled the implementation of realtime seismic monitoring as a management tool, quantifying rockmass response to mining and achieving the first tangible results with prediction. A seismic event, being a sudden inelastic deformation within the rockmass, can now routinely be quantified in terms of seismic moment, its tensor, and radiated seismic energy, so that the overall size of, and stress released at, the seismic source can be estimated.
Book Synopsis Seismicity in Mines by : G. Gibowicz
Download or read book Seismicity in Mines written by G. Gibowicz and published by Birkhäuser. This book was released on 2012-12-06 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent seismological research has focused on processes other than pure shear failure (double-couple) as an alternative mechanism for some types of seismic events. This has been stimulated by what appears to be anomalous focal mecha nisms observed for several earthquakes of possible volcanic nature in the 1980 Mammoth Lakes, California sequence (JULIAN and SIPKIN, 1985; SIPKIN, 1986). Although studies have concentrated on earthquakes associated with magmatic processes, possible non-double-couple seismic failure has been observed, but not widely known, in cases of mine seismicity in the past three decades. Such cases have occurred on a world-wide basis; however, no cases until now have been observed in the United States. The existence of non-double-couple failure in mine seismicity has been controversial as it has been for tectonic/volcanic earthquakes. Several of the benchmark studies of mine seismicity in the deep South African gold mines have resulted in the belief that no fundamental distinction in the source mechanism exists between tectonic earthquakes and rock bursts (MCGARR, 1984); both types of events are the result of pure shear failure. However, the reported cases of implo sional focal mechanisms for mine seismicity continue to increase in number and prolong the controversy. During the summer of 1984, a three-dimensional, high resolution micro earthquake network was operated by Woodward-Clyde Consultants (WCC) in the vicinity of two coal mines beneath Gentry Mountain in the eastern Wasatch Plateau of central Utah.
Book Synopsis Microseismic Monitoring by : Vladimir Grechka
Download or read book Microseismic Monitoring written by Vladimir Grechka and published by SEG Books. This book was released on 2017-09-01 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, microseismic monitoring, a technology developed for evaluating completions of wells drilled to produce hydrocarbons from unconventional reservoirs, has grown increasingly popular among oil and gas companies. Microseismic Monitoring, by Vladimir Grechka and Werner M. Heigl, discusses how to process microseismic data, what can and cannot be inferred from such data, and to what level of certainty this might be possible. The narrative of the book follows the passage of seismic waves: from a source triggered by hydraulic fracture stimulation, through hydrocarbon-bearing formations, towards motion sensors. The waves’ characteristics encode the location of their source and its focal mechanism. The analysis of various approaches to harvesting the source-related information from microseismic records has singled out the accuracy of the velocity model, fully accounting for the strong elastic anisotropy of hydraulically fractured shales, as the most critical ingredient for obtaining precise source locations and interpretable moment tensors. The ray theory complemented by its modern extensions, paraxial and Fréchet ray tracing, provides the only practical means available today for building such models. The book is written for geophysicists interested in learning and applying advanced microseismic data-processing techniques.

Book Synopsis Mine Seismology: Data Analysis and Interpretation by : S.N. Glazer
Download or read book Mine Seismology: Data Analysis and Interpretation written by S.N. Glazer and published by Springer. This book was released on 2016-04-27 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers an in-depth analysis and interpretation methods applicable to mine-induced seismicity. It is based on over 40 years of experience in mine and exploration geophysics. Another unique feature of this book is the complete history of the caving process as evidenced by the recorded seismicity at the South African copper mine Palabora Lift 1. Until now, the literature has only presented theory and case studies discussing the interpretation of results, and there has been no discussion of the input-data quality or why a certain interpretation technique was applied. This book fills that gap. This book is a fascinating read, written by one of the world’s leading mine seismologists. It summarises the history and progression of mine seismology. It outlines the practical use of back analysis of data and how it can be used on a daily basis. The book explains how mine seismology can be used as an effective monitoring tool for key events as the mine progresses as well as for future caving operations.Anthony Allman MAusIMM, CP(Min), RPEQ Antcia Consulting Pty Ltd, Director, Mining Engineer The content of the book is really solid and robust and I have no doubt it is going to be considered a great contribution for the mining community.Raul Fuentes, Former Director of Master Program in Geomechanics Applied to Mining, Universidad de los Andes, Santiago, Chile This book is long overdue and helps to present some difficult concepts in a way that they can be clearly understood by non-experts in this area. Stefan has personally managed to take mine seismology from being a black-art into a useful tool to help make mines a safer and more controlled environment. Neil Hepworth C. Eng, MIMMM, Geomin Consultorio – Brazil, Consultant Mining and Geotechnics Seismic monitoring is an important tool in cave management. The information from monitoring allows a number of key production factors to be determined including cave advance rates, the approximate location of the cave back, insight into the size of the air gap and allows the tracking of broad changes in stress. These all assist in the day to day management of a safe and successful cave. Dr. Glazer’s book provides guidance on the application of microseismicity to cave management through a review of appropriate theory and more importantly illustrates its use through case histories, particularly from the Palabora block cave. The text will be a good addition for all practitioners in cave engineering and operations.Allan Moss, General Manager – Grasberg Underground Liaison, Copper Development, Rio Tinto

Book Synopsis Mine Seismology: Seismic Warning Concept by : S.N. Glazer
Download or read book Mine Seismology: Seismic Warning Concept written by S.N. Glazer and published by Springer. This book was released on 2017-10-03 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book illustrates how mine seismology can be used to improve underground safety standards. It describes several preventive actions that have been put into practice at the 5B Area of No. 5 Shaft Vaal Reefs gold mine after issuing seismic warnings. These included additional safety pillars, changes in mining sequences and directions, and a review of the mining strategy for the entire 5B area. The presented experiment with seismic warning concept was a success because it was an internal mine project. Further, the Vaal Reefs management adopted the philosophy that the success rate should be measured in the preventive actions taken, not in the success of the prediction itself. Reviewing these and other aspects, the book clearly demonstrates how mine seismology can effectively improve underground safety standards. Stefan Glazer’s book (...) addresses in a very comprehensive manner both technical and practical problems of implementing and then effectively using microseismic networks and data. (...) Stefan proves that through comprehensive microseismic data analysis the location of potential rock burst can be assessed and then prevention action plans can be developed, providing more confidence to management and workers that deposit[s] can be mine[d] safely. Michal Stawski, VP Strategic Geomechanical Specialist, PT Freeport Indonesia I began reading this story expecting to find a technical review of the science of seismology and its application in mining, [but] this book is much more than that. (...) This is a must-read for those managing seismically active mines and should provide a wake-up call to the industry as the complex morality surrounding the management of seismic risk needs to be clarified in order for this to advance. Eric Strom, Director Underground Mining, New Gold Inc. As a mining geotechnical practitioner having experience in large open pit and underground massive mining operations, I have learned that mining induced seismicity can have a significant impact on the safety and economics of operations. However, seismicity is a complex field that is generally left to specialists with little input from geotechnical engineers and engineering geologists. (...) This is a must read for mine seismologists, geotechnical practitioners and mining engineers alike, and will be a welcome and much needed addition to my own book cabinet. This will be [an] invaluable work as our industry progresses to the mining of new depths in both the underground and open pit environments.

Book Synopsis Rock Mass Response to Mining Activities by : Tadeusz Szwedzicki
Download or read book Rock Mass Response to Mining Activities written by Tadeusz Szwedzicki and published by CRC Press. This book was released on 2018-06-14 with total page 211 pages. 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.
Download or read book Induced Earthquakes written by S.K. Guha and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 314 pages. 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.

Book Synopsis Mine Seismology: Seismic Response to the Caving Process by : S.N. Glazer
Download or read book Mine Seismology: Seismic Response to the Caving Process written by S.N. Glazer and published by Springer. This book was released on 2018-08-01 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the results of seismic data analysis and interpretation based on nearly one million seismic events. This seismicity was induced by the caving process in four copper mines, each located on a different continent. The book not only serves as an interpretation guide, it also illustrates the benefits of evaluating data from different mines: How to establish which seismic data base is faulty and why The formation of a universal seismic response to the caving process Indisputable evidence that hydro-fracturing improves underground safety This book invites discussion on more general aspects of research, such as: Basic research, applied research and implementation Predicting mine-induced seismic events Quantitative versus qualitative seismology Research versus pseudo-research What is genuine research? [In the Parlabora Mine] Stefan has demonstrated that [the] use of the seismic system was a very practical means of monitoring the progression of the cave up to and beyond break through into the open pit above. The seismic system was vital in drawing up the undercutting and seismic protocols and determining the maximum potential seismic hazard level. Peter Townsend Retired Mine Manager and Consultant I consider Stefan the pioneer of using microseismic data to provide understanding of the mechanism and progress of cave mining. Science has advanced considerably since the use of less than reliable extensometers to monitor the cave back position and Stefan was leading this advance. (...)This book provides a lot of useful insight[s] in how we can best understand the data that we (...) gather and how to change this data into useful information. Neil Hepworth C. Eng, MIMMM, Geomin Consultorio – Brazil. Consultant Mining and Geotechnics Stefan mine seismology trilogy is (...) a comprehensive tutoring on how to analyse and interpret mine induced seismicity. This coaching is based on multiple practical examples (...) presented from the problem to be solved [with] input data tests followed by analysis and interpretation. This last is presented with many details that explain the whole process. Mahdi Bayuargo, ST, MAScPT. Duaem Gada Bayuagus Managing Director

Book Synopsis Guidelines for Slope Performance Monitoring by : Robert Sharon
Download or read book Guidelines for Slope Performance Monitoring written by Robert Sharon and published by CSIRO PUBLISHING. This book was released on 2020-07-01 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although most mining companies utilise systems for slope monitoring, experience indicates that mining operations continue to be surprised by the occurrence of adverse geotechnical events. A comprehensive and robust performance monitoring system is an essential component of slope management in an open pit mining operation. The development of such a system requires considerable expertise to ensure the monitoring system is effective and reliable. Written by instrumentation experts and geotechnical practitioners, Guidelines for Slope Performance Monitoring is an initiative of the Large Open Pit (LOP) Project and the fifth book in the Guidelines for Open Pit Slope Design series. Its 10 chapters present the process of establishing and operating a slope monitoring system; the fundamentals of pit slope monitoring instrumentation and methods; monitoring system operation; data acquisition, management and analysis; and utilising and communicating monitoring results. The implications of increased automation of mining operations are also discussed, including the future requirements of performance monitoring. Guidelines for Slope Performance Monitoring summarises leading mine industry practice in monitoring system design, implementation, system management, data management and reporting, and provides guidance for engineers, geologists, technicians and others responsible for geotechnical risk management.
