Abstract: Energy source analysis is a systematic safety risk analysis method based on unexpected energy release theory, and it gives coal mine enterprise a new angle to carry out risk identification and can improve the comprehensiveness of mine enterprise safety analysis. ESA firstly divided the analysis object into different energy units, identified the energy sources existed in each energy units, and then analyzed the risk of the unexpected energy release and the factors that cause the release of energy. According to the results of ESA in T coal mine, the reasons that cause the accidents are people’s unsafe behavior, unsafe status of matters and the management factors. Through the results compared with control measures of coal mine, we can find out the weakness of the enterprise safety management, so as to take measures to improve the safety management level of mine enterprise.
