Available in PDF, EPUB and Kindle. Book excerpt: This report serves as a compilation of developmental, design, and test data for three types of yieldable rock bolts which have been developed and tested. The three types of bolts (termed herein the South African, Bureau of Mines, and Omaha District rock bolts) represent the major thrusts in rock bolt developmental work to date. Much of the information presented was summarized from published reports and personel communications with the designers. The rock bolts evaluated in this study were of two basic types: the 'die-thread' type (the South African and Bureau of MInes bolts) and the 'plug-tubing' type (the Omaha District bolt). With both types of yielding mechanisms the physical shape or configuration of the component parts was shown to be of critical importance. For the two yieldable rock bolts the sensitivity of yield loads to construction methods appears to be comparable.

This book was released on 2021-06-23 with total page 796 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive introduction to rock mechanics treats the basics of rock mechanics in a clear and straightforward manner and discusses important design problems in terms of the mechanics of materials. This extended third edition includes an additional chapter on Foundations on Jointed Rock. Developed for a complete class in rock engineering, this volume uniquely combines the design of surface and underground rock excavations and addresses: • rock slope stability in surface excavations, from planar block and wedge slides to rotational and toppling failures • shaft and tunnel stability, ranging from naturally-supported openings to analysis and design of artificial support and reinforcement systems • entries and pillars in stratified ground • three-dimensional caverns, with emphasis on cable bolting and backfill • geometry and forces of chimney caving, combination support and trough subsidence • rock bursts and bumps in underground excavations, with focus on dynamic phenomena and on fast and sometimes catastrophic failures. The numerous exercises and examples familiarize the reader with solving basic practical problems in rock mechanics through various design analysis techniques and their applications. Supporting the main text, appendices provide supplementary information about rock, joint, and composite properties, rock mass classification schemes, useful formulas, and an extensive literature list. The large selection of problems at the end of each chapter can be used for home assignment. A solutions manual is available to course instructors. Explanatory and illustrative in character, this volume is suited for courses in rock mechanics, rock engineering and geological engineering design for undergraduate and first year graduate students in mining, civil engineering and applied earth sciences. Moreover, it will form a good introduction to the subject of rock mechanics for earth scientists and engineers from other disciplines.

Available in PDF, EPUB and Kindle. Book excerpt: 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
