摘要
文章利用FDS软件建立柳塔煤矿井下12煤通风系统巷道的三维模型;在矿井采空区域遗留矿柱设置火源,采用混合分率燃烧模型模拟火灾烟气蔓延过程;通过对FDS模拟结果进行分析,得到烟气温度、能见度等参数随时间的变化规律,确定火灾危险区域,为矿井实施反风及制定反风应急预案提供理论依据。
In this paper, built the 3D model of the Coal Mine twelfth Liuta＇s coal ventilation system and then the left pillar and fire at the mined areas, the process of smoke spreading is simulated with use of the model of mixture fraction combustion. The parameter variation along with time including the smoke temperature and visibility in the tunnel were obtained through the analysis of the FDS simulation result, and the hazard zone during the fire was determined, which provides the theoretical basis to formulate emergency olan and conduct mine anti-wind.
