井下紧急避险设施内人体舒适度预测模型

Prediction model of human comfort index in underground emergency refuge facilities

长时间处在不舒适的环境中,将对人体健康产生严重影响。井下紧急避险设施中,影响避险人员舒适性感觉的因素众多,本文选取氧气含量、二氧化碳含量、温度和相对湿度四个关键因素为研究对象,采用分级评分法,进行了系列真人模拟生存试验,获得了单一环境变量和多个环境变量条件下总计169组有效人体舒适度投票数据.经统计分析,分别得出了密闭舱室内单一环境变量与人体舒适度感觉之间的函数关系以及避险人员舒适度预测模型,分析了氧气含量、二氧化碳含量、温度和相对湿度的允许范围及调控原则.

The psychology and physiology of miners would be damaged if they continue to stay in uncomfortable environments for long time. When waiting for rescue in emergency refuge facilities, numerous factors can affect comfortable feelings of miners. In this paper, four crucial factors, including oxygen concentration, carbon dioxide concentration, temperature and relative humidity, were selected as the study objects. Adopting the grading method, a series of human live experiments were performed to obtain vote data under both a single and multiple environmental variables. The functional relation between human comfort degree and environmental variables were got by statistically analyzing these vote data. A mathematical model was proposed to predict the human comfort degree of miners in refuge confined space. The allowable ranges of oxygen level, carbon dioxide level, temperature and relative humidity along with their controlling principles were discussed in the end.
