利用矿岩自燃发火巷道烟气流动所遵循的控制方程,对烟气流动特性进行数值了模拟。通过模拟计算得出了发火巷道内烟气流动的速度场、温度场详细分布情况。并采用预计热舒适指标(PMV)、预计不满意百分比(PPD)对巷道中的空气质量进行了评价。利用模拟计算结果,可以为铜坑矿地下火和毒气蔓延的控制以及火区特大事故应急救援预案的制定提供技术依据。
The properties of fire smoke flow in fire tunnel was simulated and computed by using fire flow control equations. The distribution of velocity and temperature of the smoke flow in the fire tunnel was calculated by the simulation. The quality of the air in the fire tunnel was evaluated by using the Predicted Mean Vote (PMV) and Predicted Percent Dissatisfied (PPD). The simulation results could provide a technical basis for controlling the fire and preventing the smoke spread, and making the scheme of accident urgent rescue.
