Course Outcomes
- Understand the physical and mechanical properties of rocks relevant to mining engineering.
- Analyse stress and strain behaviour of rock masses under various loading conditions.
- Apply laboratory and field-testing methods to determine rock strength and deformation characteristics.
- Design rock support systems such as bolting, shotcrete, and grouting for underground excavations.
- Evaluate the stability of rock slopes, tunnels, and underground openings using rock mass classification systems.
