Seismicity represents one of the major threats of the mining industry. It affects the mining personnel safety, the operations, and the profitability of the mine. When it is impossible to eliminate the probability of occurrence of a major seismic event, some measures need to be implemented to reduce the probability of seismically induced rockfalls (rockbursts). This is generally achieved with the installation of enhanced ground support systems, also often referred to as dynamic ground support systems. The design of (dynamic) ground support systems in mine facing rockburst-prone conditions is often based on the experience and knowledge acquired at each mine, which made their methods specific to their conditions. Stacey (2012) concluded that since the dynamic capacity of ground support systems and the demand from seismically induced dynamic loading cannot be reliably quantified, then "...a clear case of design indeterminacy" results, making it "...impossible to determine the required support using the classical engineering design approach". This master's thesis aimed at developing a better understanding of the influence of combinations of ground motion factors (GMFs) and various geotechnical conditions on the reliability of numerous ground support strategies subjected to dynamic loading conditions The performance of ten ground support systems strategies have been investigated for a range of GMF expressed as a function of the seismic event magnitude and distance between the seismic source and damage. The performance criterion is the survivability of the ground support system (i.e., no fall of ground, although rehabilitation may be required). A reliability index was developed to classify the reliability of the performance. Results are shown as a survivability matrix, which will be used to assist in the selection of ground support systems in underground mines facing rockburst-prone conditions.

Rock Dynamics – Experiments, Theories and Applications is a collection of scientific and technical papers presented at the Third International Conference on Rock Dynamics and Applications (RocDyn-3, Trondheim, Norway, 26-27 June 2018). The papers in the book reflect the recent developments in experiment and theory as well as engineering applications of rock dynamics. Rock dynamics studies the response of rock and rock masses under dynamic loading and during the state transition from static loading to kinetic movement. It also includes the study of engineering countermeasures to dynamic instability of rock and rock masses. The topics in the book include: - Dynamic theories - Numerical simulation - Propagation of stress waves - Dynamic tests of rock - Stability of underground openings under dynamic loading - Rockburst - Seismic monitoring - Dynamic rock support - Blasting - Earthquake-related rock structure damage, etc. Applications, such as rockburst, dynamic rock support, seismic monitoring, blasting and earthquake-related rock structure damage, are paid special attention in Rock Dynamics – Experiments, Theories and Applications. The papers, from specialists both from mining and tunnelling branches, discuss commonly interested dynamic issues. Their experience and knowledge in the application of rock dynamics are extremely valuable for all academics, engineers and professionals who work with rock dynamics.

The purpose of ground support is to safely maintain excavations for their expected lifespan. The effectiveness of ground support can be seen both in terms of personnel and equipment safety, and in terms of allowing the most economic extraction. Scientists, practitioners and technology developers have contributed to this volume, which covers rock ma

Excavation, Support and Monitoring is the fourth volume of the five-volume set Rock Mechanics and Engineering and contains twenty-three chapters from key experts in the following fields - Excavation Methods; - Support Technology; - Monitoring Technology; - Integrated Engineering Monitoring and Analysis. The five-volume set “Comprehensive Rock Engineering”, which was published in 1993, has had an important influence on the development of rock mechanics and rock engineering. Significant and extensive advances and achievements in these fields over the last 20 years now justify the publishing of a comparable, new compilation. Rock Mechanics and Engineering represents a highly prestigious, multi-volume work edited by Professor Xia-Ting Feng, with the editorial advice of Professor John A. Hudson. This new compilation offers an extremely wide-ranging and comprehensive overview of the state-of-the-art in rock mechanics and rock engineering and is composed of peer-reviewed, dedicated contributions by all the key experts worldwide. Key features of this set are that it provides a systematic, global summary of new developments in rock mechanics and rock engineering practices as well as looking ahead to future developments in the fields. Contributors are world-renowned experts in the fields of rock mechanics and rock engineering, though younger, talented researchers have also been included. The individual volumes cover an extremely wide array of topics grouped under five overarching themes: Principles (Vol. 1), Laboratory and Field Testing (Vol. 2), Analysis, Modelling and Design (Vol. 3), Excavation, Support and Monitoring (Vol. 4) and Surface and Underground Projects (Vol. 5). This multi-volume work sets a new standard for rock mechanics and engineering compendia and will be the go-to resource for all engineering professionals and academics involved in rock mechanics and engineering for years to come.

The safe and economical construction of tunnels, mines, and other subterranean works depends on the correct choice of support systems to ensure that the excavations are stable. These support systems should be matched to the characterstics of the rock mass and the excavation techniques adopted. Establishing the support requirements, designing support systems and installing these correctly are essential elements in safe underground construction. This is a comprehensive and practical work which also gives access to user-friendly computer programmes which enable the investigation and design of support techniques. Details on how to obtain this software are also included in the book.

This new edition has been completely revised to reflect the notable innovations in mining engineering and the remarkable developments in the science of rock mechanics and the practice of rock angineering taht have taken place over the last two decades. Although "Rock Mechanics for Underground Mining" addresses many of the rock mechanics issues that arise in underground mining engineering, it is not a text exclusively for mining applications. Based on extensive professional research and teaching experience, this book will provide an authoratative and comprehensive text for final year undergraduates and commencing postgraduate stydents. For profesional practitioners, not only will it be of interests to mining and geological engineers, but also to civil engineers, structural mining geologists and geophysicists as a standard work for professional reference purposes.
