基于未确知测度理论,建立了矿井人体热舒适性等级评价模型.从矿井热环境和人体自身因素出发,考虑了影响人体热舒适性的10项因素,根据实测数据和调查结果建立各影响因素的未确知测度函数.该模型针对矿井人体热舒适评价中的诸多不确定性影响因素,根据实际情况,分别对其进行定性、定量分析,并利用熵权理论计算各影响因素的指标权重,依照置信度识别准则进行等级判定,最后得出人体矿井热舒适性的评价结果.将该方法用于某高温铜矿6个不同中段的热舒适性评价,并与实际调查结果进行对比.结果表明,计算结果与实际情况吻合较好,可见该方法科学合理,可以在实际工程中推广应用.不同深度的矿井热舒适性不同,应采取不同的降温标准.

Based on the uncertainty measurement theory, a thermal comfort level evaluation model for human body in mines is established. With the thermal environment of mines and the special features of human body in mind, ten factors that would influence the thermal comfort of human body are identified, and the uncertainty measurement function is formulated based on the in-situ data and investigation results. The uncertainty influencing factors in the thermal comfort evaluation are determined by qualitative and quantitative analyses, respectively. The entropy weight theory is used to calculate the index weight of these factors and the credibility degree recognition criteria are established to determine the levels. The thermal comfort evaluation is made. This model is used to evaluate the six different stages of a certain copper mine. The results show that the calculation results are consistent with the empirical values of investigations, therefore, the uncertainty measurement method is reasonable and can be applied to the practical engineering. In different depths of mines, different cooling standards should be established for the thermal comfort.
