Abstract: In order to achieve the goals of visualization, automation, intelligence and standardization of the underground power
supply system in coal mines, this paper studied the whole process of the transformation of an unmanned and intelligent power
supply system in A Coal Mine. The results showed that the transformation of the unmanned and intelligent power supply system in
underground substations can solve the problems of short-circuit overstepping, group tripping due to loss of voltage, leakage and
misoperation and refusal of operation existing in the underground power supply system of coal mines, which can improve system
operation efficiency and improve system economy.

Key words: underground coal mine; substation; intelligent power supply system; unattended operation
