Course Policies: (1):No-make examination (In case of illness, make-up exam may be granted if a Doctor’s note is submitted). No early exams will be given.
(2) Plagiarism/Academic Integrity: As stated in UAF policies & Regulations
(3)Attendance is required for a passing grade.
(4)All home works, and project works need to be submitted electronically (MS word file). No hand written submission of the homework or project work will be accepted.
(5)Late submission of any homework or project work will be checked but will not count towards the final grade for the class.
Course Evaluation: The students will be evaluated based on absolute scores. Two in-class examination (Mid-term & final) will be 60% of the total grade, class-home works will consist of 15% of the grade, class project will consist of 20% of the grade, and class-participation & attendance will count for 5% of the grade.
Project(s) such as "optimum levels”, number of ore passes, development of underground coal storage bunkers, etc, will be assigned to the groups. Each project will be of considerable difficulty, and an open-ended design problem. A written report and presentation of the results will be required. The length of each project report will vary depending on the problem assigned.
The project(s) will be assigned during the first/second week of the semester, giving students adequate time to search existing literature on the subject, collect data from vendors, if necessary, and calculate the necessary information for an open-ended problem. The project report will follow the conventional formats in the mining engineering field, and at a minimum, will have (1) literature review, (2) Assumptions made, (3) Solution approach (4) Justificationfor the solution approach, (5) Calculations & results, (6) Conclusions, and (7) References.
Homework consists of 15 % of the total grade. A set of Homework will be assigned every three weeks , beginning the second week of the semester. A total of five sets of homework will assigned during the semester.
A student who receives 90% or above will get an “A” grade, 85-90% will get a “B” grade, 80-85% will count for a B-, etc.
Support Services: Student Tutors within CEM would be helpful.
Disabilities Services:Will follow UAF rules & regulations.
