Abstract：In view of the health and safety problems caused by the influence of high temperature environment on the workers in the underground mechanical and electrical equipment chamber of coal mine,in order to re-duce the incidence of heat related diseases and improve the thermal comfort and work efficiency for coal mine workers,through the on-site questionnaire and experimental tests,the results show that the degree of psycho-logical annoyance caused by high temperature was"very annoyed",the heart rate,axillary temperature,oral temperature and blood lactic acid concentration of the miners increased significantly,the vital capacity,self-regulating ability and pain perception ability decreased significantly,and the ability to concentrate and respond decreased,and the dark adaptation ability basically remained unchanged.The correlation model between hu-man axillary temperature,oral temperature and ambient temperature was established,and the operation tem-perature limit in mine electromechanical equipment chamber is 34.6℃.
