Although "Rock Mechanics" Addresses Many of the Rock Mechanics Issues Which Arise in Underground Mining Engineering, It is Not a Text Exclusively for Mining Applications. It Consists of Five Categories of Topics on the Science and Practice of Rock Engineering Basic Engineering Principles Relevant to Rock Mechanics; Mechanical Properties of Rock and Rock Masses; Design of Underground Excavations in Various Rock Mass Conditions; Mining Methods and Their Implementation; and Guidelines on Rock Mechanics Practice. Throughout the Text, and Particularly in Those Sections Concerned With Excavation Design and Design of Mining Layouts, Reference is Made to Computational Methods of Analysis of Stress and Displacement in a Rock Mass. the Principles of Various Computational Schemes, Such As Boundary Element, Finite Element and Distinct Element Methods, Are Considered. This New Edition Has Been Completely Revised to Reflect the Notable Innovations in Mining Engineering and the Remarkable Developmen
