This practical guide describes the stage-by-stage development of a method for predicting the penetration rate (PR) and the advance rate (AR) for tunnel boring machines based on an expanded version of the Q-value, QTBM. The author analyzes 145 TBM tunnels that total 1,000km in length. He then develops simple formulae to estimate PR and AR from the QTBM value and to back-calculate QTBM from performance data. The book quantitatively explains actual advance rates as high as five m/hr for one day or as low as 0.005 m/hr for several months. It also covers logging methods, empirical TBM tunnel support design, and numerical verification of support.

Seismic 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.

Practical Engineering Geology provides an introduction to the way projects are managed, designed and constructed, and how the engineering geologist can contribute to cost- effective and safe project achievement. The need for a holistic view of geological materials, from soil to rock, and of geological history is emphasised. Chapters address key aspects of Geology for engineering and ground modelling Site investigation and testing of geological materials Geotechnical parameters Design of slopes, tunnels, foundations, and other engineering structures Identifying hazards Avoiding unexpected ground conditions This second edition includes a new chapter on environmental issues covering hydrogeology, considerations of climate change, earthquakes, and more. All chapters have been updated, with extensively revised figures throughout and several new case studies of unexpected ground conditions. The book will support practising engineering geologists and geotechnical engineers, as well as MSc level students of engineering geology and other geotechnical subjects.

Economic Mineralization - the volume sets out to present various aspects of a very broad details of a narrow field of economic mineralization at a time when the competitively growing global economy and the pressing needs of the society are compelling economic geology to grow and pile of data is accumulating and opinions changing very rapidly. The volume incorporates papers, a resultant of information explosion and electrifying conceptual revolution in economic geology, describing the new and exciting results and timely reviews integrating and immense amount of knowledge in the field of geology, exploration, mining, environment, economics, geophysics and geochemistry that has bearing on economic mineralization. The book imbibes sections on crustal evolution and economic mineralization, economic mineralization of igneous application, economic mineralization of sedimentary affiliation, prospecting and exploration and mining, economics and environments. In all the five sections current concepts, problems and probable trends of future research are highlighted. This book will be an invaluable everlasting reference for both industry and academia specializing in economic mineralization and for those who need updated information and current research in the field. It will be equally useful for advance level geology and mining students and research scholars throughout the world.

With the ever-increasing developmental activities as diverse as the construction of dams, roads, tunnels, underground powerhouses and storage facilities, petroleum exploration and nuclear repositories, a more comprehensive and updated understanding of rock mass is essential for civil engineers, engineering geologists, geophysicists, and petroleum and mining engineers. Though some contents of this vast subject are included in under-graduate curriculum, there are full-fledged courses on Rock Mechanics/Rock Engineering in postgraduate programmes in civil engineering and mining engineering. Much of the material presented in this book is also taught to geology and geophysics students. In addition, the book is suitable for short courses conducted for teachers, practising engineers and engineering geologists. This book, with contributions from a number of authors with expertise and vast experience in various areas of rock engineering, gives an in-depth analysis of the multidimensional aspects of the subject. The text covers a wide range of topics related to engineering behaviour of rocks and rock masses, their classifications, interpretation of geological mapping of joints through stereographic projection, in situ stress measurements, laboratory and field tests, stability of rock slopes, foundations of structures, including dams and support systems for underground excavations. The Third Edition of the book is further enriched with the addition of a number of case histories in which the analyses and designs were carried out by adopting rock mass parameters as per RMR, Q or GSI. The consequence of such an approach is critically examined. With the adoption of parameters from joint factor, excellent performance prediction has been demonstrated for anisotropic rocks and tunnel. Various expressions developed for Kn and Ks for different conditions are included for adoption in numerical analyses. When dilatancy component is separated, the scale effect on shear response is insignificant. This edition provides a comprehensive understanding of rock mass response and enables students to tackle rock engineering problems more confidently and realistically, and therefore it will be of immense benefit to students, teachers, professionals and designers alike.
