摘要:
为了解决倾斜巷道火灾期间高温毒害烟气严重威胁井下人员避灾和救援等问题，采用Fluent数值模拟和1∶20缩尺火灾实验的方法，对不同巷道坡度下的烟气运动和温度变化进行研究。研究结果表明：添加细水雾和纵向通风都会降低倾斜巷道火灾温度。对于细水雾，下游顶板温度随着巷道坡度的增大而减小；对于纵向通风，控烟降温效果随巷道坡度的增大而降低。研究结果可为倾斜巷道防排烟设计以及对火灾下风侧烟气蔓延控制和救援提供参考。
Abstract:
In order to solve the problem that the high temperature and toxic smoke during the fire of inclined roadway seriously 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 water 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 during fires.
