Two computer program sections to determine the fume or other contaminant exposures of underground miners were developed. One section deals with exposure at fixed points of the ventilation system, the other deals with the exposure of miners traveling along specified escapeways. The feasibility of combining the latter section with an existing mine evacuation program was investigated. Modifications were devised and the evacuation plan and contaminant exposure of 10 miners is presented. Based on the assumption that a nonsteady-state process can be approximated by a sequence of short- duration, steady-state processes, a new program for the non-steady- state simulation of ventilation systems under the influence of mine fires was developed.
