Abstract: In order to solve the psychological trauma problems caused by coal mine accidents, based on the situation of coal mine accidents in China and related research results at home and abroad, psychological effects on the miners of coal mine accidents were explored, and the corresponding countermeasures were proposed. The results showed that there would be a series of psychological stress reactions on miners after coal mine accidents. If seriously, it might turn into acute stress disorder and post traumatic stress disorder (PTSD). And the degree of psychological trauma was often related to the severity of accident, miner's personality characteristics, cognitive assessment, traumatic experiences, social supporting and so on.
