Simulation of Leaky Ventilation Circuits with SLAM II

Solutions to typical leaky ventilation circuits such as multiple entry headings and ventilation tube or brattice face ventilation are obtained using the discrete continuous simulation language SLAM II. While the continuous aspect of the language allows exact numerical solution of leaky systems, the particular discrete-continuous interface of this language is easily adapted to space varying geometry and flow parameters encountered in mine ventilation. The ease with which this simulation system is adapted to ventilation problems and the availability on personal computers encourage its wider application in the field.
