Simulation and research on the condition of smoke near the mine fire source by CFAST

摘要

The current mine fire uses the one-dimensional network simulation generally,it not useful for the analysis of the region near the mine fire.On the basis of Two-dimensional smoke flowing theory and simulation technology in roadway,the paper uses the newest edition of CFAST 6.10 by Nist to simulate and research the characteristic of smoke flowing and temperature in the vicinity of the mine fire.Validate the applicability of zone model in the simulation of mine fire,put out the accurate elementary condition for the next simulation with One-dimensional.
