Book Description :

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

Book Description :

The Canada-Ontario-Industry Rockburst project was initiated in 1984 because of the re-emergence of a serious rockbursting problem in some of Ontario's mines. This report reviews the accomplishments realized during the first 5 years of the project, from 1984-89. The report describes the problem of seismicity in Ontario mines, seismic monitoring systems, scaling relationships, and the work conducted at the mines at Elliot Lake, Kirkland Lake, Red Lake, and Sudbury by each company involved. A list of publications and the personnel involved in the project are also included.

Understanding the evolution patterns for the microstructure instability of rock is a prerequisite for rockburst prediction. The book provides a guide for readers seeking to understand the evolution patterns for the microstrucure of rock failure, the predicting key point of rock failure and the rockburst predicting model. It will be an essential reference to understand mechanism of rockburst and sheds new light on dynamic disasters prediction. Chapters are carefully developed to cover (1) The evolution patterns for the microstructure instability of rock; (2) Rockburst hazard monitoring and predicting criterion and predicting models. The book addresses the issue with a holistic and systematic approach that investigates the occurrence mechanism of rockburst based on the evolution patterns for the microstructure of rock failure and establishes the predicting model of rockburst. This book will be of interest to researchers of mining engineering, rock mechanics engineering and safety engineering.

Book Description :

This book investigates the evolution process of rockburst based on the energy dissipation theory and proposes appropriate active prevention and control technologies. It discusses the electromagnetic radiation (EMR) generated by coal rock fractures as a measurement of the amount of dissipated energy, and the use of EMR to experimentally observe the time domain characteristics of energy dissipation during coal rock failure processes. It then proposes the concept of the rockburst activity domain system (RADS), establishes a dynamic pressure model of rockburst, and describes the energy criterion for rockburst instability. Lastly, it presents two waterjet cutting-based cases of pressure relief and rockburst prevention. The book serves as a reference resource for mine safety workers, engineering technicians, scientists, graduate students and undergraduates engaged in research on dynamic hazards such as rockburst..

Book Description :

[Truncated abstract] This thesis deals with the topic of rockburst damage in hard rock, mechanised underground mines. Specifically, given a seismic event occurs at or near an excavation boundary, what factors specific to the characteristics of that excavation determine whether or not rockburst damage occurs and the severity of that damage? These findings were used to develop a probabilistic and empirical based system for assessing the rockburst damage potential of an excavation. An extensive literature review was undertaken to identify the current state of understanding of the rockburst problem, as well as determining shortcomings in the understanding of the rockburst damage potential of underground excavations. The review showed that there was no widely adopted or effective method of determining the likelihood and severity of rockburst damage. A large catalogue of rockburst case histories was collected. The catalogue comprised of 254 instances of rockburst damage from 13 hard rock, metalliferous, mechanised underground mines in Australia and Canada. The mines cover a range of commodities, geological conditions, mining methods and ground support practices. Through preliminary assessment of these case histories it was apparent that certain excavation specific factors contributed to the occurrence and severity of rockburst damage and were common across the different mine sites. It was found that for a given magnitude seismic event at a given distance from an excavation (that is, a characteristic peak particle velocity) there is a significant amount of variation in the amount of rockburst damage done which is dependent on site specific factors at the damage site. The literature review identified that there was limited data available on the in situ performance of complete ground support systems when subjected to dynamic loading. Simulated rockburst experiments using blasting were carried out to attempt to reproduce the strong dynamic loading generated during rockbursts and to quantify the effects on a range of commonly used ground support systems. Thirteen ground support systems were subjected to the test method across six different underground test sites at various Western Australian mines..... The five factors were combined through a multiplicative relationship into a single index named Rockburst Damage Potential (RDP). Probabilistic analysis using logistic regression was carried out to determine RDP distributions against a five-point rockburst damage scale. The distributions were used to create a system for assessing the likelihood and severity of rockburst damage in seismically active underground mines. It was found that the RDP system had a success rate of up to 78% in forecasting the level of rockburst damage when the rockburst catalogue data was back analysed. The RDP system was applied to a Western Australian underground mine. This demonstrated its use in a real underground mining situation for both the real-time assessment of seismic risk as well as the forward risk assessment of future mine plans and mining options. The RDP system was built into the MS-RAP software, allowing real-time visualisation and assessment of seismic risk. The MS-RAP software is now in use at many seismically active mines in Australia, Canada, Chile and Sweden, with many sites making use of the RDP capabilities.
