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.

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

Seismic interferometry is a technique by which the Green's function or impulse response between two receivers is recovered through the cross-correlation of the transmission responses recorded by those receivers. This technique has found several applications, including the generation of virtual shot gathers from ambient seismic noise for use in seismic reflection processing. In March of 2013, 336 receivers were deployed over the volcanogenic massive sulphide (VMS) deposit found at the Lalor mine in Manitoba, Canada. Approximately 300 hours of ambient seismic noise was recorded for the purpose of testing the effectiveness of seismic interferometry in imaging a crystalline rock environment. A time-domain beamforming algorithm was implemented to determine the locations of the sources present during recording. The results indicate that the vast majority of the recorded noise originated from mine and ventilation shafts located at the Lalor mine. Synthetic experiments were conducted to determine the effects such a source distribution would have on the application of seismic interferometry in the presence of dipping reflectors. The experiments show that if sources are located only on one side of a receiver line, the dip and lateral extents of reflectors will not be imaged properly. A technique involving beamforming and F-K filtering was developed to remove surface wave noise originating from near-field sources. Using this technique, the raw data was processed into virtual shot gathers free of surface wave noise. Virtual shot gathers were generated along 4 of the receiver lines and processed as separate 2-D reflection datasets. The resulting reflection profiles are compared against coincident DMO-stacked data from a larger 3-D active seismic survey conducted over the Lalor mine. Using this comparison in conjunction with knowledge of the local geology, events recovered in the passive reflection profiles are interpreted as either real reflections or spurious events, and possible explanations of their origin are given.
