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.

The basic principles of geomechanical processes occurring in mine workings during the extraction of minerals are discussed in this monograph. Particular attention is paid to the support system, specifically to the various roof-bolt and frame support designs, and also to the modern means providing resource-saving conditions for ensuring mine workings sustainability. The basic principles of the computing experiment performance at the modelling of geomechanical processes are also presented and the stress-strain state of "rock massif – mine working support" systems are investigated. Finally, the results of field studies are discussed and illustrated. Modern studies are presented in this work, the advanced support systems are introduced and the solution to the problem of low-cost rock pressure control in mine workings is described. Further the unique study in the thin-layer massif of weak rocks is conducted and the technical and economic aspects of mine workings maintenance during rocks heaving are described. The book will be of interest to scientists in research and design organizations in the mining sector, engineers and technological workers in mines, as well as university academics and students.

- 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. - 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
