摘要: 基于 2019 年山东“11·19”火灾事故,利用 PyroSim软件构建压入式掘进巷道内的火灾模型,实现了总长 400 m、火源位于 200 m 处的掘进巷道内,风筒烧断与未烧断两种情况、不同火源功率下的火灾模拟。结果表明:在压入式巷道中发生火灾,一旦风筒烧断,火灾发展将更加迅速;一定条件下巷道中火场内被困区温度、烟气遮光率随时间推移和风流作用会迅速增大;火源功率越大,被困区受到危险的时间越短。

Abstract: Based on the“11·19”fire accident in Shandong in 2019, using PyroSim software, a fire simulation of a pressed driving tunnel with a total length of 400 m and a fire source located at 200 m was performed for both the blown and unblown ducts in the tunnel and different fire source powers. The results showed that: if a fire occurs in a press-in tunnel, the fire will develop more quickly once the wind tunnel is blown out; under certain conditions, the temperature, smoke shading rate of the trapped area in the fire field in the tunnel will increase rapidly with time and wind effect; the greater the power of the fire source, the shorter the time the trapped area is at risk.

Key words: mine fire, PyroSim, numerical simulation, press- in ventilation
