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: In the last several years there has been a great increase of seismicity in the Khibiny Massif. This began to manifest itself after large volumes of rocks had been extracted from a high-stress environment in connection with the mining activity for the Khibiny apatite deposits. In particular, the increase in the seismicity has been significant after 1980. During this same time period the annual ore excavation at the Khibiny mines has increased from 19.1 to 46.5 million tons. A geometrical correspondence between the configuration of the mines and the coordinates of Khibiny earthquake epicenters has been detected. We have reviewed the mining practice in the Khibiny Massif, and compiled detailed statistics on explosion times and explosive charge sizes. We have demonstrated a correlation between the yields of underground explosions and their magnitudes. The overall correlation (using all underground explosions) is about 0.72, but it is as high as 0.89 when considering explosions from Mine only. This mine has deeper underground part and well recorded underground explosions. When considering open-pit explosions, we note that other investigators have been unable to find any correspondence between the (aggregate) yields and the seismic magnitudes. We attribute this difference to the different shot practice for open-pit and underground explosions. Some of the increased seismicity in the Khibiny Massif is possibly connected with the open-pit mining, and could be associated with the removal of large volumes of rock, causing a change in the stress regime. In particular, this manifests itself in a gradual displacement of lines of equal seismic energy release in the direction of Mine. Our results thus support the conclusions in previous studies that the rock extraction from a high-stress environment can cause increase in overall seismicity.

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.
