摘要：

为明确矿用通风服对人体热生理的影响效果,探究不同环境温度、人体劳动强度、矿用通风服管路结构及通风量与人体热生理反应的关系,基于人工环境试验舱以及试验测量仪器,开展真人受训试验,收集记录试验数据,分析在36种不同工况下3种不同管路结构矿用通风服的人体热生理变化情况,结合双变量相关分析功能,寻求3种管路结构下不同环境温度、服装通风量、劳动强度3因素与人体热生理之间的相关性。结果表明:3种通风服衣内微空间的风量分布均匀性为横向型>混合型>竖向型。针对整体效果而言,在同一工况下,管路结构影响显著程度由高到低依次为横向型、混合型和竖向型;环境温度主要影响平均皮肤温度与心率,通风量主要影响收缩压与舒张压,劳动强度主要影响出汗量。

Abstract:

In order to analyze the effect of mine ventilation clothing on human thermal physiology, and to explore the relationship between different ambient temperature, human labor intensity, pipeline structure and ventilation volume of mine ventilation clothing and human thermal physiological response, a human training test was carried out based on artificial environment test chamber and test measuring instrument, and test data were collected and recorded. By analyzing the human thermal physiological changes of three different pipeline structures of mine ventilation clothing under 36 different working conditions, combined with bivariate correlation analysis function, the correlation between three factors of different ambient temperature, clothing ventilation volume and labor intensity and human thermal physiology under three pipeline structures was sought. The results show that the uniformity of air volume distribution in the micro space of three kinds of ventilated clothes is transverse type > mixed type > vertical type. In terms of the overall effect, under the same working condition, the influence of pipeline structure from high to low is transverse type, mixed type and vertical type; the ambient temperature mainly affects the average skin temperature and heart rate, the ventilation volume mainly affects the systolic blood pressure and diastolic blood pressure, and the labor intensity mainly affects the sweating volume.

Key words: mine ventilation suit, thermal physiological response, pipeline structure, labor intensity
