Research on influence of water mist and longitudinal ventilation on smoke movement in inclined roadway fire
In order to solve the problem that the high temperature and toxic smoke during the fire of inclined roadway serious-ly threatens the disaster avoidance and rescue of underground personnel,the Fluent numerical simulation and 1 ∶ 20 scaled fire experiments were used to study the smoke movement and temperature change under different roadway slopes.The results show that adding water mist and longitudinal ventilation can both reduce the fire temperature in inclined roadway.For the wa-ter mist,the downstream roof temperature decreases with the increase of roadway slope.For the longitudinal ventilation,the smoke control and cooling effect decreases with the increase of roadway slope.The research results can provide reference for the smoke control design of inclined roadways,as well as for the control and rescue of smoke spread on the windward side dur-ing fires.
