Download or read book Rockbolting written by Charlie Chunlin Li and published by Butterworth-Heinemann. This book was released on 2017-05-22 with total page 286 pages. 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

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.

Download or read book Bond Failure Mechanism of Fully Grouted Rock Bolts written by Jianhang Chen and published by Springer Nature. This book was released on 2023-06-10 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of writing this book is to provide the latest research findings in ground control techniques in mining engineering, especially the rock bolting techniques. Since rock bolts are widely used in mining engineering and civil engineering, they are significant in guaranteeing the safety of underground openings. However, instability issues still occur with the rock bolting technique. Therefore, it is valuable to understand the exact load transfer mechanism of rock bolts. This book summarised the recent research work regarding rock bolting conducted by the authors. It is valuable for the readers to fully understand the reinforcing mechanism of fully grouted rock bolts. This book focuses on the bond failure mode of fully grouted rock bolts, which is the most widely encountered failure mode in rock bolting. Different investigation approaches are used in this book, including numerical simulation, analytical modelling and experimental tests. Therefore, this book conducts a comprehensive study to reveal the bond failure process of fully grouted rock bolts. Moreover, it reveals the corresponding bond failure mechanism. Therefore, it helps the reads to fully understand the bond failure mechanism of rock bolting. Moreover, it helps the readers to develop new approaches and methods to prevent failure of the rock bolting system. This is an open access book.
Download or read book Sustainable Construction Materials and Technologies written by Yoon-Moon Chun and published by CRC Press. This book was released on 2007-05-31 with total page 1756 pages. Available in PDF, EPUB and Kindle. Book excerpt: The construction materials industry is a major user of the world’s resources. While enormous progress has been made towards sustainability, the scope and opportunities for improvements are significant. To further the effort for sustainable development, a conference on Sustainable Construction Materials and Technologies was held at Coventry University, Coventry, U.K., from June 11th - 13th, 2007, to highlight case studies and research on new and innovative ways of achieving sustainability of construction materials and technologies. This book presents selected, important contributions made at the conference. Over 190 papers from over 45 countries were accepted for presentation at the conference, of which approximately 100 selected papers are published in this book. The rest of the papers are published in two supplementary books. Topics covered in this book include: sustainable alternatives to natural sand, stone, and Portland cement in concrete; sustainable use of recyclable resources such as fly ash, ground municipal waste slag, pozzolan, rice-husk ash, silica fume, gypsum plasterboard (drywall), and lime in construction; sustainable mortar, concrete, bricks, blocks, and backfill; the economics and environmental impact of sustainable materials and structures; use of construction and demolition wastes, and organic materials (straw bale, hemp, etc.) in construction; sustainable use of soil, timber, and wood products; and related sustainable construction and rehabilitation technologies.
Download or read book Back Analysis in Rock Engineering written by Shunsuke Sakurai and published by CRC Press. This book was released on 2017-09-01 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides practicing engineers working in the field of design, construction and monitoring of rock structures such as tunnels and slopes with technical information on how to design, how to excavate and how to monitor the structures during their construction. Based on the long-term engineering experiences of the author, field measurements together with back analyses are presented as the most powerful tools in rock engineering practice. One of the purposes of field measurements is to assess the stability of the rock structures during their construction. However, field measurement results are only numbers unless they are quantitatively interpreted, a process in which back analyses play an important role. The author has developed both the concepts of “critical strain” and of the “anisotropic parameter” of rocks, which can make it possible not only to assess the stability of the structures during their construction, but also to verify the validity of design parameters by the back analysis of field measurement results during the constructions. Based on the back analysis results, the design parameters used at a design stage could be modified if necessary. This procedure is called an “Observational method”, a concept that is entirely different from that of other structures such as bridges and buildings. It is noted that in general, technical books written for practicing engineers mainly focus on empirical approaches which are based on engineers’ experiences. In this book, however, no empirical approaches will be described, instead, all the approaches are based on simple rock mechanics theory. This book is the first to describe an observational method in rock engineering practice, which implies that the potential readers of this book must be practicing engineers working on rock engineering projects.
