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.

This volume contains 18 papers from 8 countries dealing with different aspects of triggered and induced seismicity. In situ observations of the phenomenon include examples of seismicity due to reservoirs, hard-rock mines, coal mines, mine collapses, brine production caverns, fluid injections, and geothermal hot-dry-rock projects. High-frequency acoustic emission studies from laboratory experiments and hard-rock mines have also been reported. Besides providing case studies of previously unavailable observations of seismicity, the present volume contains investigations of the causes and source mechanism of seismic events, determination of source parameters, seismic hazard as related to the design of support systems for underground openings and procedures for closure of brine production caverns, and the use of seismic and non-destructive techniques in assessing rock damage, measuring dynamic elastic moduli and detecting discontinuities. This collection of papers provides an excellent indication of the state of the art, recent developments and outstanding challenges facing scientists and engineers in understanding the causes and alleviating the effects of induced seismicity.

The Netherlands, like much of the world, is struggling to balance the development of natural resources like oil and coal with its commitment to environmental preservation. In the landmark study Geology of the Netherlands, a team of expert geologists presents an overview of the Low Countries’ geology as well as contemporary problems the land faces. This lavishly illustrated volume examines the stratigraphy and structural setting of the Netherlands from the Pre-Silesian to the Quaternary eras; it will be an essential resource for geologists, engineers, and students.

This compilation of peer-reviewed papers covers the subjects of geotechnical engineering, bridge engineering, geological engineering, seismic engineering, tunnel, subway and underground facilities, hydraulic engineering, coastal engineering, surveying engineering, water supply and drainage engineering, heating, gas supply, ventilation and air conditioning works, disaster prevention and mitigation, environmentally-friendly construction and development and cartography and geographic information systems. The work will be of value to anyone working in these fields.
