"China's largest open-pit coal mine is located in Haerwusu in the Inner Mongolia Autonomous Region. It started production on 20 October 2008, and is operated by Shenhua Group. Its estimated coal output was forecast at 7 million tonnes in the fourth quarter of 2008.
With a designed annual capacity of 20 million tonnes of crude coal, it will operate for approximately 79 years. Its coal reserves total about 1.73 billion tonnes. It is rich in low-sulfur steam coal. Mines in Inner Mongolia are rapidly expanding production, with 637 million tons produced in 2009. Transport of coal from this region to seaports on China's coast has overloaded highways such as China National Highway 110 resulting in chronic traffic jams and delays.
Covering an area of 67 square kilometers, Haerwusu mine lies in the middle of the Zhungeer Coalfield. At the moment it is the open-cast coal mine with the largest production capacity in China. Work on the mine started in May 2006 and the total investment topped 7 billion Yuan. Incidentally 1 Chinese Yuan Renmimbi or 1 CYR = 1 US$ for general informations."
