Mine Design II (Design of Underground Mines and Facilities)

At the end of this course, the students should be able to: 1. explain what is involved in designing any type of underground mine and gallery; 2. select appropriate underground mining method and machineries for a given mineral deposit; 3. identify the various data required for the design of any underground mine and facility and how to acquire them; 4. recall the rules of conduct for safe working in an underground mine; 5. apply the techniques learned in designing underground mine where required; 6. apply applicable software packages for design of underground mines; 7. generate mineral model from cut-off grade; 8. design the best stope for safe operation and optimum recovery; and 9. undertake a practical design project in underground mining.
