It's an industrial mine, so you have to have a conveyor going into the purple 'furnace' part of the mine. The mines placed on the conveyor should be Coal Mines, either basic or triple. They are worth $0 but they power up industrial mines such as this one. They also power up the Industrial Ore Welder upgrader.
