Abstract: The electric energy loss and power supply distance of 380V and 660V underground power are calculated and compared by using the method of calculation and comparative analysis.  This work was based on the current situation of the power supply of the small coal mine in Yunnan local coal mine with the example of the power supply system of a mine. It was suggested that the 380V power supply system of small  mine in Yunnan local coal mine should he upgraded to 660V. 

Key words: coal mine, power supply system, electric energy loss, power supply distance, comparative analysis
