Practical Handbook of Rock Mass Classification Systems and Modes of Ground Failure is a comprehensive, yet concise, guide to 16 of the most important rock classification systems and their failure modes. The book discusses these systems in relation to the design of excavations and ground reinforcement/support under passive, active, static, and dynamic mining conditions. This includes rock testing assessment, surface and underground site investigation, and any practical activity that deals with the physical and mechanical properties of rocks. The book is an excellent professional reference for geoscientists, technicians, and geological engineers doing research and consulting in mining, geological, civil, and petroleum resource fields.
