Aims of the Course 

The aim of the short course is to give the students an understanding of the different types of temperatures and the influence of water vapour on temperatures, heat transfer processes, psychrometric properties of air, air volume requirements and refrigeration principles.


Course Pre-requisites 

  • Minimum entry requirements for full MEC qualification is an Chamber of Mines Intermediate Certificate in Mine Environmental Control or the NQF 4 QCTO Ventilation Officer qualification.
  • Entry for certificate of attendance or completion of some of the modules within the MEC qualification is an Grade 12 certificate with Maths and Science. Students with matric entry will also be able to complete the assignments and exams for recognition of for the module for which they enrolled as an occasional student, but will not be able to complete all modules and will not be credited with the full qualification.
  • Entry and registration in any particular module is subject to the university’s rights to cancel an individual module.


Course Content

The content of the course will include the following:

  • Review of basic thermodynamics
  • Introduction to psychrometrics
  • Heat transfer and sources of heat in mines
  • Managing heat flux in mining excavations
  • Mine cooling principles
  • Ventilation planning principles and practice
  • Mixing of airstreams
  • Theory and calculation of auto compression and Virgin Rock Temp (VRT)


Learning Outcome

After completion of the course, delegates should be able to:

  • Use engineering methods, skill and tool to solve ventilation problems relating to heat psychrometric processes and refrigeration issues.
  • Identify natural and artificial sources of heat. 
  • Use empirical methods to estimate heat load and cooling required.
  • Recommend appropriate cooling methods for various mine situation.

Method of Assessment

Successful completion of an examination (70%) and assessment (30%).


Number of Notional Study Hours: 100
