摘　　要：Coal mining enterprises are also pillar enterprises on which the national economy depends for its development. Coal resources can effectively meet the development needs of various industries. In the process of modern coal production, mining, construction, production and application, various coal mining equipment technologies and safety technologies need to be developed and applied, and the risk coefficient in the production and operation process is relatively high. Power supply equipment is one of the core basic equipment systems of the whole coal mine operation and production activities. Its normal, safe, efficient and reliable operation is related to the major life and safety of coal mine production. Once the power supply equipment fails abnormally, it may instantly cause electrical fire accidents and other kinds of safety risk accidents. Therefore, to do a good job in the safety protection and electrical protection of coal mine power supply equipment is one of the urgent problems to be solved.
