2 Coal Power
2.1
Voltage power lines from various substations and power users will mine linking transmission, transformation, distribution and consumption of the whole.
2.2
Voltage power lines from various substations and power users will mine linking transmission, transformation, distribution and consumption of the whole.
2.3
Underground power supply system
Into the mine underground power cable, power supply units and consisting of transmission, transformation, distribution and consumption of the whole.
2.4
Downhole Face Power Supply System
Into the mine underground tunnel near the face and power cable, power supply units and consisting of transmission, transformation, distribution and consumption of the whole.
2.5
Mining area substation (refused to use)
