The principles which underlie effective ground control strategies and tactics are introduced. In situ and induced stresses around openings, design of underground openings, and design of pillars are examined, including methods of analysis using computer models. Failure mechanisms around mine openings including structurally controlled, stress controlled and rockburst mechanisms are analyzed. Principles of rock reinforcement and rock support are presented, and details of ground support systems are given, including rockbolts, dowels, cables, friction sets, shotcrete and backfill. Methods of design for ground support systems are covered. Labs include practical field work in ground support installation. PREREQ: ENGR 2346. (lec 3, lab 1.5) cr 3. Lecture (3.00).
