The major features of the CANMET thermodynamic mine ventilation network program, developed by the Mining and Mineral Process Engineering Department of the University of British Columbia for the Canada Centre for Mineral and Energy Technology (CANMET), are described. The program is designed for use by deep Canadian mines in planning ventilation flows where the effects of auto-compression of air, moisture liftwork and natural ventilation are significant. Routines to simulate stalled fans and give an optional cost printout have been included in the program. A supplementary plotting program used to simplify data interpretation is also described. The program is described with a test data example of a deep mine. It is a valuable analytical tool which can assist ventilation engineers to simulate many alternative ventilation strategies at a low cost in a very short time.
