Introduction and Site Investigations Contents include:Ground and Rock Fragmentation - Drilling and Blasting, Earth Movers, Excavators and Open-cut Excavations, Tunnelling by Conventional Methods, Mechanized Tunnelling, Shield Tunnelling in Soft Ground, Special Methods, MicroTunnelling, Raising, Sinking and Large Sub-surface Excavation, and Hazards, Safety and the Environment. Excavation is a multi-disciplined activity involving Civil, Construction and Mining Engineers, Earth-Scientists and Geologists. Hence, this book is likely to be used by the students, officials and engineers of these disciplines. This book is intended to serve as a textbook for students of undergraduate level and beginning year of graduate level at Schools or Institutes having any of the above-mentioned disciplines.
