Rockbolting: Principles and Applications brings current theoretical and practical developments in the most widely used support device for underground rock excavations. Today, one cannot find any rock excavation project that does not use rockbolts for rock support. The worldwide annual assumption of rockbolts is in the billions, with pieces applied to mines, tunnels and other types of geotechnical projects for rock and soil reinforcement. The text is based on over 25 years of experience of the author both as academic and practitioner. The book introduces the principles and background concepts of rock support, and then offers a comprehensive overview of the mechanics of rockbolting, as well as current rock bolt types such as mechanical, grouted, self-drilling, grouted cables, frictional and yield rockbolts. Installation and performance assessment are covered next including load-displacement curves and energy-absorption capacities. Two chapters on design and quality control, respectively, cover failure mechanics, the selection process and the connections with other supporting devices. On quality control, the author explains the usual tests and displacement measurements. The final chapter brings current case studies that combine the concepts presented in the whole book. The book is a professional reference for engineers in the mining and geotechnical industries and can be used as research material for academics in rock mechanics and stability studies. - Offers theoretical knowledge on rock bolts and rockbolting - Covers the standard and most recent types of rockbolts - Includes information on rockbolting in high stress rock - Presents case studies that introduce practical applications in several conditions

This includes the Proceedings of the international symposium, Abisko, Sweden, 28 August-2 September 1983. Rock bolts today represent the dominant support system in mines and underground structures. Some results and experiences are discussed to give a better understanding of the strength of individual rock bolts and systems of bolts, and the interaction between bolts and rock masses of various types. Topics covered are as follows: rock bolting in theory and experiments; design principles and experience; and ground control and instrumentation: cable bolting.

First published in 1993. This volume is a collection of papers addressing the issue of the failure of rock engineering structures. This phenomenon occurs in different forms depending on the geometry of structure, material properties of intact rock, structure of rock mass, environmental conditions and initial state of stress.

Papers in the proceedings of the 32nd U.S. Symposium on Rock Mechanics were solicited to address the theme of 'Rock Mechanics as a Multidisciplinary Science'. The major goal was to assemble scientists and practitioners from various fields with interrelated interests in rock mechanics to share their common problems and approaches. The proceedings include three papers related to a special session on 'Lunar Rock Mechanics', as well as 121 technical papers covering areas such as: field observations, in-situ stresses, instrumentation/measurement techniques, fracturing, rock properties, dynamics/seismicity, modelling, laboratory testing, discontinuities/fluid flow, design, wellbore stability, and analysis.

Advances in Rock-Support and Geotechnical Engineering brings together the latest research results regarding the theory of rock mechanics, its analytical methods and innovative technologies, and its applications in practical engineering. This book is divided into six sections, rock tests, rock bolting, grouted anchor, tunneling engineering, slope engineering, and mining engineering. Coverage includes fracture hinged arching process and instability characteristics of rock plates, failure modes of rock bolting, scale effects, and loading transfer mechanism of the grouted anchor. Also covered are recent innovations and applications in tunneling engineering, slope engineering, and mining engineering. This book provides innovative, practical, and rich content that can be used as a valuable reference for researchers undertaking tunneling engineering, slope engineering, mining engineering, and rock mechanics, and for onsite technical personnel and teachers and students studying the topics in related universities. - Enriches new theories on failure modes of rock plates, rock bolting mechanisms, and anchor loading transfer - Develops new methods of evaluating the stability of slope engineering and the roof stability of the mined-out areas - Includes fracture hinged arching process and instability characteristics of rock plates, failure modes of rock bolting, scale effects, and loading transfer mechanism of the grouted anchor

The text broadly covers recent developments in ground control techniques, and their at operating mines, worldwide. Specific topics include: design and analysis of support and re-inforcement in metalliferous mines, mesh, shotcrete and membrane support systems, and strata control in coal mines.

An up-to-date record of the most recent developments and thinking in the methods, problems and challenges in the field of rock support, including cable bolting, shotcrete in mining, support in rockburst-prone ground, and support design, analysis and applications.
