Tongling, Anhui, was named after copper and prospered with copper. It is known as "China's ancient bronze capital and contemporary copper base".
The Dongguashan Copper Mine, located in the suburbs of Tongling City, is a deep mine with a depth of more than one kilometer. The mine is known as the largest deep mine in Asia.
Here, every day, more than 2,000 miners are fighting in the underground mine, which is 1,000 meters deep, to stand silently and work hard.
Nowadays, Dongguashan Copper Mine has realized unmanned electric locomotive transportation in the middle section of 1,000 meters underground. The rumbling electric locomotive in the mine automatically transports the ore. The workers sit in the central control room and the temperature is suitable for all seasons.
Technology is changing the life of a kilometer underground.
