MINE 449 - Design of Excavations (2 units)
Principles of Geomechanics and numerical models are used in design of special mining excavations, such as: large underground mining stopes, rock slopes, tunnels, shafts, measure ground subsidence, and other special mining excavations.
Prerequisite(s): MINE 448 .
Grading Basis: Graded
Units of Lecture: 2
Offered: Every Spring
Student Learning Outcomes
Upon completion of this course, students will be able to:
1. describe how the following impact tunnel design: Terzaghi’s rock load theory, strength of discontinuities, tunneling hazards, tunneling machines, tunneling in swelling rocks.
2. describe how the following impact shaft design: Self-supporting shaft, support pressures on the wall of shaft, design of support system, surge shaft, shaft excavation.
3. describe ground subsidence considerations: Characterization of ground movements, chimney cave, caving rock, support near caving ground, ground movements monitoring.
4. perform design and analysis using numerical modeling methodologies and tools.
