Beskrivning

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 bookconducts 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.

Mer om författaren

Jianhang CHEN got his bachelor degree in Mining Engineering from the China University of Mining and Technology. In 2012, he got the financial support provided by the China Scholarship Council and started his PhD at the University of New South Wales, Australia. In 2016, he got his PhD degree in Australia. After that, he started working as an academic staff in the China University of Mining and Technology (Beijing). In 2020, he was promoted as an Associate Professor. His research interests include the ground control techniques in mining engineering and the corresponding rock bolting mechanism. As the first author, he published 25 academic papers. Among them, 20 academic papers are indexed in the Web of Science. Moreover, 9 academic papers are published in the JCR Q1 ranking journals, such as the Tunnelling and Underground Space Technology, International Journal of Mining Science and Technology, Construction and Building Materials. Two academic papers were listed as the Highly Cited Papers by the Essential Science Indicators. One is the paper of "Numerical simulation of fully encapsulated rock bolts with a tri-linear constitutive relation" which was published in Tunnelling and Underground Space Technology. The other is the paper of "Analytical studying the axial performance of fully encapsulated rock bolts" which was published in Engineering Failure Analysis. As the principal, he is hosting four national grants supported by the China government.
