| Brief description of the Unit |
| This unit provides a comprehensive understanding of the fundamental principles, techniques, and safety protocols involved in the process of rock excavation. Students learn about various drilling methods, explosive types, blast design, and environmental considerations. The unit equips students with the expertise needed to plan, execute and oversee safe and efficient rock excavation operations across different geo-mining conditions. |
