Abstract
Mine Vent is a mine ventilation analysis system which runs inside AutoCAD and uses the Penn State and other ventilation simulators. Working from AutoCAD as-mined and projected mine maps, the user picks the node locations and connects them with branches that correspond to the airway paths. Where survey data is not available, the system uses formulas to compute resistances. The system prompts the user for necessary parameters but the branch lengths are automatically computed. Powerful editing features reduce the time to modify existing schematics and try alternative ventilation options. The system also includes a survey data reduction module which outputs pressure drops and quantities values to feed the branch resistance calculator. Output includes color coded schematics with pressures and quantities shown. If the fan curve data have been digitized, the fan operating points are shown on the curves. Tabular output is also available.
