Prerequisite(s): MINE 350 . Corequisite(s): ME 311 .
Grading Basis: Graded
Units of Lecture: 2
Units of Laboratory/Studio: 1
Offered: Every Spring
Student Learning Outcomes
Upon completion of this course, students will be able to:
1. describe the behavior of the mine air flowing through underground mine openings (e.g. vertical, horizontal) and auxiliary ventilation ducts.
2. assess and size primary and auxiliary ventilation fans, explore fan arrangements (e.g. series & parallel) and determine their operating duties.
3. perform ventilation system optimization exercises to reduce underground energy consumption, while delivering the required air volumes to the development and production workings, equipment maintenance shops, crushing and refueling stations.
4. describe gases and contaminants which are generated in the production workings (e.g. diesel exhaust), classification of gases, gas detection and monitoring systems.
5. explain the importance of primary and auxiliary ventilation systems to dilute and control contaminants below their threshold limit values (TLV).
6. assess the climatic conditions in the stopes and throughout a mine.
7. predict the underground climatic conditions of future underground mines based on their combined heat load and independent contribution of various heat sources.
8. predict the climatic conditions in underground mines as a function of mining depth and the combined heat load by means of climatic simulation methods and techniques (Climsim, Ventsim).
9. describe the thermoregulation process of the human body, the metabolic heat balance and identify the most appropriate heat stress index that can protect mine workers in hot and humid underground mines.
10. perform emergency response procedures and protocols in case of underground fires and other underground emergency situations.
11. explore novel underground ventilation design concepts based on “discrete-event” mining process simulation and integrate underground ventilation system design with the overall mine design process.
12. describe the concept of “ventilation-on-demand” (VOD) control; list the main components of typical VOD systems.
13. perform optimization exercises on primary and auxiliary ventilation systems by means of mine ventilation simulation techniques.
