Abstract: Simulation software for mine fire of ventilation network was used in the whole network computer simulation of fire in underground horizontal laneway and in inclined laneway respectively.The simulation results included the time and temperature of smoke and hot gas invading laneways, withdrawing routes of mine workers, critical airflow velocities for backflow occurrence, distance of the backflow if any and key points of rescue work.The simulation results indicated that this software has the advantages of reliable calculation results, friendly interface and practical functions and therefore, can be used as an important means for performance-based design of mine fire safety engineering.

Key words: Mine fire, Simulation, Expert system, Performance-based design
