Abstract: This paper introduced the personal protective technology research process in high temperature mine and analyzed the personal protective technology application in Huainan and Huaibei high temperature mine. By wearing and not wearing personal protective equipment, the paper compared the test results of two groups 'experimental personnel in high temperature mine. The result indicates that high temperature protective equipment has thermal comfort and can regulate human physiological and biochemical indexes, especially when other cooling measures do not reach the high temperature environment, which is the best choice to provide cooling of health treatment.
