EGBC National Exam — Mining and Mineral Processing Engineering, 09-Mmp-A2 Underground Mining Methods and Design, 2014-Dec. 3 hours duration, closed book; only an approved Sharp or Casio calculator permitted, one hand-written 8.5×11 in. reference sheet allowed. Question 1 is compulsory (40 marks, all seven parts 1.1–1.7); a candidate then selects THREE of Questions 2–7 (each nominally 20 marks, Question 7 sub-totalling higher).
