Abstract: This paper mainly introduced the existing problems in the underground coal mine power supply system, analyzed the
reasons for the over-level tripping of current coal mine underground power supply system, and discussed the effective countermeasures
to solve the over-level tripping problem of coal mine underground power supply system. Pay attention to the research of
underground coal mine power supply system, ensure the normal operation of coal mine underground power supply system, and
improve the safety of underground coal mine power supply, which can lay a solid foundation for underground coal mine operations,
ensure the life safety of underground coal mine workers and maximize the benefits of underground coal production.

Key words: underground coal mine; power supply system; over-level tripping; power supply protection facilities
