摘要: 针对高海拔矿井井下通风环境差及通风能耗浪费问题,通过修正的高海拔矿井平均热感觉指数(PMV)模型,评价高海拔矿井作业人员的动态热舒适性。根据典型工况日的气象参数信息计算井上逐时热舒适度,生成井上逐时热舒适度曲线控制图,并通过建立的井下PMV模型,拟合生成井下仿自然热环境控制曲线,实时反映井下作业人员的热舒适感变化情况。研究表明:井上环境12:00—19:00时间段内舒适度为稍凉,7:00—12:00与19:00—3:00舒适度为凉,3:00—7:00舒适度为冷,经试验验证修正后的PMV模型适用于高海拔低气压环境,优化后井下热舒适度0:00—12:00及18:00—0:00舒适度为中性,12:00—18:00舒适度为稍暖;优化后的井下热舒适指标更接近人体热舒适感的最优值。

Abstract: In order to help address problems of poor ventilation and waste of ventilation energy consumption in high-altitude mines, dynamic thermal comfort evaluation for operators was conducted through a modified PMV model. Firstly hourly thermal comfort on mine surface was calculated according to meteorological parameter information of typical working days, and a control chart of it was generated. Then, an underground PMV model was established to obtain control curves of natural thermal environment underground, which reflected changes of operators' thermal comfort in real time. The results show that comfort of surface environment is slightly cooler during 12:00-19:00, cooler during 7:00-12:00 and 19:00-3:00, and cold during 3:00-7:00. The PMV model tested and verified by experiments is suitable for high-altitude and low-pressure environment. After optimization, underground thermal comfort at 0:00-12:00 and 18:00-0:00 is neutral, and it is slightly warmer at 12:00-18:00. Optimized underground thermal comfort index is closer to optimal value of human thermal comfort.
