摘　　要：为科学评价矿井热环境,采用层次分析(Analytic Hierarchy Process,AHP)、熵权和改进雷达图模型相结合的方法对矿井热环境进行综合评价。在矿井热环境评价及人体热舒适度分级标准研究成果基础上,以风温、相对湿度、风速等气候环境作为影响矿井热环境的主要因素,构建矿井热环境评价体系。将AHP和熵权法耦合以确定各评价指标权重,并基于改进的雷达图模型确定矿井热环境各评价等级的评估区间和评价对象的评估值。最后,以孟村煤矿401101采煤工作面上隅角为实例进行热环境评价,得到401101采煤工作面上隅角热环境综合评价值为0.2050,评价等级属于“等级Ⅴ很不舒适”,评价结果与现场情况相符。基于组合赋权雷达图的矿井热环境评价模型能够准确、定量、直观地展示矿井热环境状况,可为矿井优化井下热环境提供参考。The purpose of this paper is to establish a scientific,reasonable,intuitive and vivid evaluation model to display the results of mine thermal environment evaluation,to evaluate the mine thermal environment status.Based on the research results of mine thermal environment evaluation and the classification standard of human thermal comfort,the climatic environment such as wind temperature,relative humidity,and wind speed is selected as the main factors affecting the thermal environment of the mine.The mine thermal environment evaluation model is established by the combined weighting method and the improved radar chart method.The AHP and the entropy weight method are coupled through the distance function to calculate the weight of each evaluation index,taking into account the subjective experience knowledge and objective data information,to obtain more accurate information.Based on the improved radar map model,the evaluation interval of each evaluation level of the thermal environment of the mine and the evaluation value of the evaluation object are determined,and the evaluation results are visually and vividly displayed in the two-dimensional map.The established evaluation model is used to evaluate the corner thermal environment of the 401101 coal mining face in Mengcun Coal Mine.The results show that the comprehensive evaluation value of the thermal environment at the corners of the 401101 coal mining face is 0.2050,the evaluation level belongs to the"level V-very uncomfortable",and the evaluation results are consistent with the field conditions.The evaluation model can accurately,quantitatively,and intuitively display the thermal environment of the mine,and can provide a reference for optimizing the underground thermal environment of the mine.
