The occurrence of rockbursts poses a significant and growing threat to mines--and miners--throughout North America. High stress on brittle rock structures during mining operations can produce sudden, explosive reactions that result in costly mine failures, serious injury, and even death. Using a series of case studies, this essential reference documents the experiences of 15 of the most rockburst-prone mines in the US and Canada over the last century. The book provides an historical analysis of rockburst activity along with state-of-the-art strategies for anticipating and preventing this dangerous and disruptive phenomenon. This vital resource provides a primer on rockbursts, including an examination of the conditions that favor their occurrence. The text highlights practical methods to alleviate this danger, including controlling blasting times, changing mining methods, altering the extraction sequence, utilizing backfill, employing de-stress blasting, and using yielding supports. Packed with dozens of cost-saving and potentially life-saving ideas, this book is an important resource for mining engineers and operators who work in hard-rock mines. Chapters include: The Rockburst Phenomenon Brunswick Mine (Bathurst, New Brunswick) Lake Shore Mine (Kirkland Lake, Ontario) Lake Shore and Wright-Hargreaves Mines at Depth Macassa Mine (Kirkland Lake, Ontario) Falconbridge No. 5 Shaft (Sudbury, Ontario) Strathcona Mine (Onaping, Ontario) Creighton Mine (Sudbury, Ontario) Copper Cliff North Mine (Sudbury, Ontario) Quirke Mine (Elliot Lake, Ontario) Campbell Mine (Red Lake, Ontario) Lucky Friday Mine (Mullen, Idaho) Star Mine (Burke, Idaho) Galena Mine (Wallace, Idaho) Sunshine Mine (Kellogg, Idaho) Rockbursting at Kirkland Lake and Coeur d'Alene)

These proceedings include the latest developments in research and practice in the area of mining-induced seismicity. Three themes are explored: strong ground motion and rockburst hazard; mechanics of seismic events and stochastic methods; and monitoring of seismicity and geomechanical modelling.

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

In a one-year study period, 1750 seismic events with hypocenters in the vicinity of active slopes at the Lucky Friday Mine in northern Idaho were recorded on the mine seismograph. Using far-field first-motion data recorded by a district-wide network of surface seismographs, well-constrained fault-plane solutions were determined for 250 of these events. The preferred modes of failure of the events were, in order of importance: (1) right-lateral strike-slip movement along steeply dipping planes, striking northwest; (2) normal faulting along northerly striking planes, and (3) oblique thrust faulting along randomly striking, shallow, shallow dipping planes. Tectonic stress, rather than mining-induced stress, appears to exert the greater influence on the seismicity occurring in the vicinity of the active stopes. This is especially true for those events locating below the bottom longwalls.

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.
