Rock Quality, Seismic Velocity, Attenuation and Anisotropy
by Nick BartonSeismic measurements take many forms, and appear to have a universal role in the Earth Sciences. They are the means for most easily and economically interpreting what lies beneath the visible surface. There are huge economic rewards and losses to be made when interpreting the shallow crust or subsurface more, or less accurately, as the case may be.
Rock Reinforcement and Rock Support (ISRM Book #6)
by Ömer AydanThe stability of underground and surface geotechnical structures during and after excavation is of great concern as any kind of instability may result in damage to the environment as well as time-consuming high cost repair work. The forms of instability, their mechanisms and the conditions associated with them must be understood so that correct stabilisation of the structure through rock reinforcement and/or rock support can be undertaken. Rock Reinforcement and Rock Support elucidates the reinforcement functions of rock bolts/rock anchors and support systems consisting of shotcrete, steel ribs and concrete liners and evaluates their reinforcement and supporting effects both qualitatively and quantitatively. It draws on the research activities and practices carried out by the author for more than three decades and has culminated in a most extensive up-to-date and a complete treatise on rock reinforcement and rock support.

Rock Stress and Earthquakes
by Furen XieThe evaluation of in-situ rock stress is not only important in the exploration and engineering involving rock masses for mining, hydropower, tunneling, oil and gas production, and stone quarrying, but also in the geodynamics and earthquake prediction. The methods of determining these stresses for shallow crust in the engineering practice, including
Rock Support and Reinforcement Practice in Mining

Rock | Water | Life: Ecology and Humanities for a Decolonial South Africa
by Lesley GreenIn Rock | Water | Life Lesley Green examines the interwoven realities of inequality, racism, colonialism, and environmental destruction in South Africa, calling for environmental research and governance to transition to an ecopolitical approach that could address South Africa's history of racial oppression and environmental exploitation. Green analyzes conflicting accounts of nature in environmental sciences that claim neutrality amid ongoing struggles for land restitution and environmental justice. Offering in-depth studies of environmental conflict in contemporary South Africa, Green addresses the history of contested water access in Cape Town; struggles over natural gas fracking in the Karoo; debates about decolonizing science; the potential for a politics of soil in the call for land restitution; urban baboon management; and the consequences of sending sewage to urban oceans.
Rockburst Evolutionary Process and Energy Dissipation Characteristics
by Dazhao Song Xueqiu He Enyuan Wang Zhenlei Li Jie LiuThis book investigates the evolution process of rockburst based on the energy dissipation theory and proposes appropriate active prevention and control technologies. It discusses the electromagnetic radiation (EMR) generated by coal rock fractures as a measurement of the amount of dissipated energy, and the use of EMR to experimentally observe the time domain characteristics of energy dissipation during coal rock failure processes. It then proposes the concept of the rockburst activity domain system (RADS), establishes a dynamic pressure model of rockburst, and describes the energy criterion for rockburst instability. Lastly, it presents two waterjet cutting-based cases of pressure relief and rockburst prevention. The book serves as a reference resource for mine safety workers, engineering technicians, scientists, graduate students and undergraduates engaged in research on dynamic hazards such as rockburst..
Rockburst in Extra-Thick Coal Seam Mining: Mechanism and Prevention
by Sitao Zhu Fuxing Jiang Xiufeng Zhang Jinhai LiuThis book provides a detailed introduction to the mechanism of rockburst in extremely thick coal seam mining and explores the mechanical mechanism on why the critical depth of rockburst in extremely thick coal seam mining is significantly smaller than that in thin to thick coal seams, it also proposes targeted monitoring, warning, and treatment technologies. The prevention and control of coal mine rockburst is a global problem, attracting engineers and scientists from various disciplines such as mining, geology, geophysics, and civil engineering to conduct research. This book provides multiple case studies of rockburst accidents in mining of ultra-thick coal seams and provides a detailed analysis of the mechanisms and treatment technologies of each rockburst accident. It aims at graduate students, researchers, and on-site engineers who are interested in the mechanism of rockburst occurrence, monitoring, early warning, and treatment technology. The translation was done with the help of artificial intelligence. The present version has been revised technically and linguistically by the authors in collaboration with a professional translator.

An account of these methods as applied in German coal mines, the deepest in the world. Contents: Rockbursts & similar phenomena; Conditions of occurrence; Influence of rock stress; Bursting & nonbursting coal; Long-term prevention; Direct prevention; Borehole patterns for direct prevention; Destressing methods; Case histories.

Rocks and Minerals in Thin Section
by W. S. MacKenzie A. E. Adams K. H. BrodieThis concise, clear and handy–sized volume, aimed at the undergraduate level, provides an introduction to the observation, description and identifi cation in thin section, using the polarizing microscope, of samples of the commonlyoccurring rocks and minerals. Illustrated with a wealth of full colour thin section photomicrographs, and with the original images enhanced by new examples and a revised text, the book explains how to observe mineral and rock samples under the microscope. The book highlights the important diagnostic features of minerals and deals with all rock types – igneous, sedimentary and metamorphic – each with equal emphasis and authority, giving students the knowledge and confi dence to begin to identify specimens for themselves. While intended for students in geology, geography, civil engineering and materials science, the book stands on its own as a beautiful collection of photomicrographs and a permanent source of reference and fascination for all those interested in the nature and science of the world of rocks and minerals.
