Book Description
Rock mechanics is a first course in the field of mining and geotechnical engineering. Over the last decades, the concepts and applications of rock mechanics have evolved tremendously for understanding the stability and safety of structures made of/on the rock masses. This book elaborates the fundamental concepts of rock mechanics for designing and analysis of structures and excavations for a variety of applications. The text includes a fine blend of theory and worked-out examples and applications, and also emphasises the basics of stress and strain analysis, volume–weight relationship, rock mass classification systems, in situ stress measurements, stresses around underground opening, pillar and support design, subsidence, slope stability, rock failure criteria and behaviour of jointed rock mass. Numerical analysis procedures and interaction between rock bolts and rock masses are also introduced emphasising the mechanics and applications in rock engineering. Besides undergraduate and postgraduate students of civil (including geotechnical), mining and petroleum engineering, the book will also benefit the practicing engineers and researchers, who wish to acquaint themselves with state-of-the-art techniques of rock mechanics and its applications. Overall, this textbook is useful for both elementary as well as advanced learning.

Book Description
The crash of an Amtrak train near Baltimore, the collapse of the Hyatt hotel in Kansas City, the incident at Three Mile Island, and other large-scale technological disasters have provided powerful examples of the ways that communication practices influence the events and decisions that precipitate a disaster. These examples have raised ethical questions about the responsibility of writers within agencies, epistemological questions about the nature of representation in science, and rhetorical questions about the nature of expertise and experience as grounds for judgments about risk. In The Rhetoric of Risk: Technical Documentation in Hazardous Environments, author Beverly Sauer examines how the dynamic uncertainty of the material environment affects communication in large regulatory industries. Sauer's analysis focuses specifically on mine safety, which provides a rich technical and historical context where problems of rhetorical agency, narrative, and the negotiation of meaning have visible and tragic outcomes. But the questions Sauer asks have larger implication for risk and safety: How does writing function in large regulatory industries? What can we learn from experience? Why is this experience so difficult to capture in writing? What information is lost when agencies rely on written documentation alone? Given the uncertainties, how can we work to improve communication in hazardous and uncertain environments? By exploring how individuals make sense of the material, technical, and institutional indeterminancies of their work in speech and gesture, The Rhetoric of Risk helps communicators rethink their frequently unquestioned assumptions about workplace discourse and the role of writers in hazardous worksites. It is intended for scholars and students in technical writing and communication, rhetoric, risk analysis and risk communication, as well as a wide range of engineering and technical fields concerned with risk, safety, and uncertainty.

Book Description
Weak rocks encountered in open pit mines cover a wide variety of materials, with properties ranging between soil and rock. As such, they can provide a significant challenge for the slope designer. For these materials, the mass strength can be the primary control in the design of the pit slopes, although structures can also play an important role. Because of the typically weak nature of the materials, groundwater and surface water can also have a controlling influence on stability. Guidelines for Open Pit Slope Design in Weak Rocks is a companion to Guidelines for Open Pit Slope Design, which was published in 2009 and dealt primarily with strong rocks. Both books were commissioned under the Large Open Pit (LOP) project, which is sponsored by major mining companies. These books provide summaries of the current state of practice for the design, implementation and assessment of slopes in open pits, with a view to meeting the requirements of safety, as well as the recovery of anticipated ore reserves. This book, which follows the general cycle of the slope design process for open pits, contains 12 chapters. These chapters were compiled and written by industry experts and contain a large number of case histories. The initial chapters address field data collection, the critical aspects of determining the strength of weak rocks, the role of groundwater in weak rock slope stability and slope design considerations, which can differ somewhat from those applied to strong rock. The subsequent chapters address the principal weak rock types that are encountered in open pit mines, including cemented colluvial sediments, weak sedimentary mudstone rocks, soft coals and chalk, weak limestone, saprolite, soft iron ores and other leached rocks, and hydrothermally altered rocks. A final chapter deals with design implementation aspects, including mine planning, monitoring, surface water control and closure of weak rock slopes. As with the other books in this series, Guidelines for Open Pit Slope Design in Weak Rocks provides guidance to practitioners involved in the design and implementation of open pit slopes, particularly geotechnical engineers, mining engineers, geologists and other personnel working at operating mines.

Book Description
This book consists of selected papers presented at the International Conference on Geotechnical Challenges in Mining, Tunneling and Underground Infrastructures (ICGMTU), held as a virtual conference on December 20, 2021. The papers represent the research work in the related fields of underground mining, ground control, mining geotechnics, geo-instrumentation, mine tunnelling, and underground structures. It focuses on the latest technology being implemented including artificial intelligence and machine learning applications to solve challenges in mining tunneling and geotechnical structure engineering. It also highlights the state-of-the-art technologies adopted by the civil and mining industry for their commercial as well as environmental benefits. The papers are presented by an international pool of academics, research scientist, and industrial experts and therefore cater to the global audience from the field of underground engineering.
