The occurrence of electromechanical accidents often cause casualties and property loss in drilling mining. More and more attention has been paid to the research of electromechanical accidents. This paper mainly analyzes the influencing factors of electromechanical accidents and the relationship between various factors. First, the statistics data of electromechanical accidents in 19 mines in China were collected, and the status of each factor in each mine was scored by expert scoring method. The data obtained were analyzed by least square fitting method. According to the analysis of influence factors, including electrical status, personnel quality, management level and production environment, the various factors and the electromechanical accident frequency have a negative relationship; influence on the electromechanical accident frequency factors in degree from big to small was electromechanical status, degree of management level and personnel quality and the working environment.
