井下火灾中逃生人员健康度评价模型

在井下火灾逃生过程中,矿井人员在有害环境影响下的身体状况对其逃生的成功与否具有决定性作用。提出了井下火灾中逃生人员健康度的概念,综合分析了热辐射、有毒气体、烟尘颗粒及缺氧等危害因素对井下人员健康度的影响。基于模糊综合评价方法,建立了上述危害因素对逃生人员健康度的影响评价模型,并建立了人员在逃生过程中的健康度的动态评价方法。利用火灾模拟软件FDS对井下火灾实例进行了简单模拟,模拟结果验证了该评价方法的实用性和有效性。人员健康度能够对复杂灾害环境中的逃生人员状态进行综合评价,为井下灾害中的逃生路径决策提供量化的标准。

Health degree evaluation model of miners escaping from a mine fire

The physical condition of miners escaping from a mine fire in the harmful circumstance is critical to the success of escape. This paper proposed the concept of health degree of escaping miners and analyzed the effect of each harmful factor. A model was built to evaluate all factors' influence on escaping miners based on fuzzy comprehensive evaluation approach, and then a dynamic health degree evaluation method of miners escaping from a mine fire was proposed. Fire Dynamics Simulator (FDS) software was used to simulate a simplified mine fire, and escaping miner's health degree was calculated using the method. The rationality of the method was verified by the experiment. Miner's health degree can evaluate miner's physical state in complex disaster environment synthetically, and it provides a quantifiable basis to guide the decision-making of escape path in the underground disasters.
