MIN 317 - MINE POWER AND DRAINAGE
Fall Semester 2003
___________________________________________________________________________
Upon completion of this course you will be familiar with the selected aspects of mine drainage, and mine power
distribution and use. This knowledge will assist you in interfacing with the related professions (electrical,
mechanical, other engineers) and in optimization of mine performance. BLACKBOARD is used to administer this
course offering: blackboard.umr.edu. Make sure that you have the access and that you know how to use BBd.
To benefit from this course you need to have understanding of Fluid Mechanics (prerequisite: Civ. Eng.230)
___________________________________________________________________________
Lectures: Tuesdays and Thursdays from 11:00 am to 11:50 PM in Rm. 245 McNutt
Laboratories: Tuesdays at 3:30 PM in Rm. 245 McNutt (see below for more detail)
Instructor: Professor Tad S. Golosinski, Room 280 McNutt, Golosins@umr.edu

LABORATORIES
Lab format: Six laboratories are scheduled for this course. Details of timing, student assignment to a specific
group and other related matters will be announced during the lectures.
Lab Report: The report is to be typed with a minimum of five pages and a maximum of eight pages including title
page, plots, drawings and appendix. Following format is to be used:
A. Cover page: Institution, student name & ID, Lab title and an executive summary
B. Body of the report:
1. Objective
2. Theory and background information
3. Laboratory procedures used
4. Recorded data, its analysis and results; use graphs if applicable
5. Discussion and recommendations
6. References
C. Appendix (if applicable)
Report due date: All reports are due one week after the lab took place, or a problem was defined. Penalty of 30%
will apply if the report is submitted up to one week late, 50% during the second week and 100% for reports more
than two weeks late. Yes, you will still have to submit the report even if the penalty is 100% if you want to earn a
credit for this course.
Lab marking: Each lab report will be worth 5% (for the total of 30 % considering that there are six labs in this
course). In addition to lab content and organization, lab report will also be marked on format and writing (up to
one-fifth of the mark).
Attendance: Attendance is mandatory, except for unusual circumstances brought to the attention of the instructor
in advance and approved.
COMMENTS
 Attend the lectures, as some of the material may not be well covered in the references. Take notes. Listen to
the announcements and stick by the deadlines.
 Secure access to the listed references and make sure that you review those when appropriate.
 If you experience problems the instructor without delay.
 Talk to your friendly lecturers if in trouble, if you experience difficulties or if you have any other problems. The
sooner you talk the better the chance that the problem will be solved.
