摘要
为了研究矿井火灾蔓延规律的变化,以柳湾煤矿61122工作面为研究对象,借助FDS软件构建矿井运输巷火灾模型进行数值模拟研究。结果表明:当风速增加时,火灾烟气的逆流现象逐渐降低,火源附近的温度逐渐递减。
In order to study the changes in the law of mine fire spread,taking the 61122 working face of Liuwan Coal Mine as the research object,and a fire model for the mine transportation roadway is constructed using FDS software for numerical simulation research.The results indicate that as the wind speed increases,the countercurrent phenomenon of fire smoke gradually decreases,and the temperature near the fire source gradually decreases.
