当前矿井火灾逃生研究主要关注火灾产烟产热而忽视巷道环境本身对人员的影响,引入危险度概念,用于定量描述灾变时期各巷道逃生路径难易程度。危险度分为静态危险度和动态危险度,其中静态危险度表征巷道不同坡度和不平整度,动态危险度表征CO体积分数、巷道温度和能见度。利用FDS火灾数值模拟软件建立巷道模型,获取火灾发生发展过程中产烟产热数据。通过求取逃生过程中人体总耗氧量来表征人员危险度,在具备生存条件的前提下,筛选最优路径,为应急救援提供数据和理论指导。结果表明:基于危险度的人员逃生路径选择方法,选择的路径更加合理,有利于降低人员逃生压力,减少盲目逃生的伤亡。

In view of the current research on mine fire escape , which mainly focuses on the smoke and heat production of the fire but ignores the impact of the roadway environment on personnel, the concept of risk degree is introduced, which is used to quantitatively describe the difficulty of the escape path of each roadway during the catastrophe period. The risk degree is divided into static risk degree and dynamic risk degree, of which the static risk degree characterizes the different slope and unevenness of the roadway, and the dynamic risk degree characterizes the CO volume fraction, roadway temperature and visibility. The FDS fire numerical simulation software was used to establish a roadway model to obtain the smoke and heat production data during the development of the fire. By obtaining the total oxygen consumption of the human body in the process of escape, the risk of personnel was characterized, and the optimal path was selected under the premise of survival conditions, providing data and theoretical guidance for emergency rescue. The results show that the route selection method of personnel escape based on the risk degree is more reasonable, which is conducive to reducing the pressure of personnel escape and reducing the casualties of blind escape.
