A mine fire generates toxic gases and influences airflow in the mine ventilation network. Therefore, the knowledge of the effect of the mine fire on the network and the gas distribution in the roadways is indispensable for the management of escape, rescue and fire fighting activities. The ventilation network analysis during a mine fire will be one of the useful tools for these purposes. Also it is expected to give significant information to perform effectively mine ventilation control during a mine fire.The authors developed a computer program to simulate airflow changes and gas concentration in a network during a mine fire. The program introduces the "ventilation pressure created by a fire (natural draft effect)" and the "throttling effect" into the analysis. The performance of the program has been investigated, using the data of actual mine ventilation network data and of a fire experiment in the Experimental mine. The program is proved to give useful results to make effective countermeasures to mine fire and to make effective education about mine fires for the people who work in underground.
