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.

Provides practical solutions to the challenge of modeling and analyzing rock masses Consolidates a wealth of previously published technical papers on the subject and introduces previously unseen material This authoritative title is a key reference for any Geo-engineer. Rock masses differ considerably from man-made materials, and their properties can vary with location, direction and time. As a result there is a critical need to capture these variations via modeling and analysis. Zhu and Zhao provide an expert introduction to the techniques and analytical methods needed for studying underground excavations in fractured rock masses. The book brings together previously published and new material to provide a comprehensive and up-to-date reference.

This book is aimed at the practising engineer and engineering geologist working in tropical environments, where lands lides are mainly triggered by rain fall. This book is based on a similar work published in 1999 in Portuguese, which became the Rio de Janeiro Slope Manual. This book is an engineering guide for the design of slopes and stabilisation works in rocks and residual soils. It evolves from the cumulative experience gathered by several engineers and geologists who faced severe slope problems. The authors' experience throughout Central and South America (Costa Rica, Argentina, Bolivia, Peru, Ecuador and Venezuela) and the Far East, especially Hong Kong and Malaysia, was used as a foundation for writing this book. The work also benefits enormously from the time spent in Hong Kong in 1996 and 1997 by the first editor on sabbatical at the City University of Hong Kong, and the discussions he had with many colleagues from the Geotechnical Engineering Office (GEO) of the Hong Kong Government, especially Dr. A. Malone, Mr. w.K. Pun, Dr. A. Li, Mr. K. Ho, and Mr. y.c. Chan among others.

This book contains the Proceedings of EUROCK 2013 – The 2013 ISRM International Symposium, which was held on 23-26 September 2013 in Wrocław, Poland. The Symposium was organized by the ISRM National Group POLAND and the Institute of Geotechnics and Hydrotechnics of the Wrocław Institute of Technology. The focus of the Symposium was on recent developments in the field of rock mechanics with an emphasis on the application of rock mechanics to the extraction of natural resources, securing energy supplies and protecting of the environment surrounding rock that is subjected to engineering activities. The main topics, which were covered in the 150 papers (including six keynote papers) that make up this book are: rock mass characterization, laboratory and in-situ testing, constitutive models and numerical modeling, mathematical modeling of THM processes in rocks, mine design and ground control, underground storage and waste disposal, slope and open pit stability, dynamic phenomena in rock masses, design methodology in rock engineering, mechanical breakage of rocks, rock tunnel excavation and support, petroleum rock mechanics and geological CO2 sequestration. The book also includes the 2013 ISRM Franklin Lecture by A. Goricki on the engineering aspects of geotechnical tunnel design. The book will be of interest and value to rock mechanics researchers as well as to professionals who are involved in the various branches of rock engineering.

This comprehensive text explores the technologies and developments in excavations for any type of surface or underground excavation. The first several chapters cover unit operations, including drilling, explosives and blasting, mucking, haulage, hoisting, and supports and reinforcement. The book then describes excavation techniques for various operations, such as tunneling, raising, sinking, drifting, stoping, quarrying and surface mining, underground mining, pillar blasting, and liquidation. It also examines the design, planning, and analysis of excavations as well as the construction of surface and subsurface excavations, such as caverns. Case studies focus on heavy underground blasting during pillar recoveries.

Surface and Underground Excavations – Methods, Techniques and Equipment (2nd edition) covers the latest technologies and developments in the excavation arena at any locale: surface or underground. In the first few chapters, unit operations are discussed and subsequently, excavation techniques are described for various operations: tunnelling, drifting, raising, sinking, stoping, quarrying, surface mining, liquidation and mass blasting as well as construction of large subsurface excavations such as caverns and underground chambers. The design, planning and development of excavations are treated in a separate chapter. Especially featured are methodologies to select stoping methods through incremental analysis. Furthermore, this edition encompasses comprehensive sections on mining at ‘ultra depths’, mining difficult deposits using non-conventional technologies, mineral inventory evaluation (ore – reserves estimation) and mine closure. Concerns over Occupational Health and Safety (OHS), environment and loss prevention, and sustainable development are also addressed in advocating a solution to succeed within a scenario of global competition and recession. This expanded second edition has been wholly revised, brought fully up-to-date and includes (wherever feasible) the latest trends and best practices, case studies, global surveys and toolkits as well as questions at the end of each chapter. This volume will now be even more appealing to students in earth sciences, geology, and in civil, mining and construction engineering, to practicing engineers and professionals in these disciplines as well as to all with a general or professional interest in surface and underground excavations.
