Abstract：With the continuous upgrading of coal mine equipment manufacturing,various coal enterprises continue to explore the application of equipment with large mining height.Large-scale fully mechanized mining production equipment is also one of the core issues concerned by coal equipment enterprises.The equipment power and voltage continue to increase,which also puts forward higher requirements for the operation and design of the substation in the large mining height fully mechanized mining area.We expound several aspects of the power supply system of the substation in the supporting mining area,and put forward its own opinions on the substation in the supporting mining area of large mining height fully mechanized mining from the aspects of equipment,load,power supply mode,relay protection setting configuration,etc.,so as to realize reliable,economic and high-quality power supply and provide basic power supply guarantee for the safe production of large mining height fully mechanized mining face.Through the discussion and research of the substation in the supporting mining area,we provide reference for the power supply of the heavy fully mechanized mining face in the medium and large mines.
