Abstract

Abstract: To study the escape-route planning under the influence of air flow and fume in mine fire, a 3D simulation model for personnel escape in mine fire was built. Firstly, a three-dimensional structure model of roadway network was built as a display platform. Secondly, the wind speed and direction, as well as the spread of fire temperature and smoke mass fraction during the mine fire were calculated, based on the ventilation network calculation model and the fume spread parameter model. To obtain the personnel escape route results, influence coefficients of factors, including slope, wind speed and direction, temperature, and smoke, on the equivalent length of tunnel were determined, and a fire escape path planning algorithm was applied. Finally, a three-dimensional simulation of personnel escape during mine fire was conducted in a certain mine in China. According to the different situations of mine fire, three reasonable escape routes, i.e. ideal, available and emergency escape routes, were obtained through the simulation demonstration.
