摘要

The risk of supporting wood fire induced by methane explosions in roadway was studied by doing some research on the mechanism of it. The thermal environment of methane explosions which include the characteristics of fire flame and the temporal and spatial thermal environment was studied. Based on the research of thermal environment, the fast pyrolysis of supporting wood was carried out by using fast pyrolysis apparatus. The experiment temperature is from 592~1313 K, and the heat duration were 1 s, 2 s, 5 s, 10 s. Connected with combustion theory, the possibility of supporting wood fire induced by methane explosions was discussed from the following several aspects: fuel, combustion limit, the minimum combustion oxygen limit, and fire period. If the initial methane concentration is between 5.0～9.25% with someone volume, then the sub-fire may occur at a certain distance from explosion source.
