Antaipu is one of the world’s largest open-pit coal mines in the city of Shuozhou in northern China's Shanxi Province. It covers an area of more than 370 square kilometers. It was China's first project in cooperation with a foreign company in the 1980s amid the country's opening-up drive. The mine's coal reserves stand at 12.6 billion tons, and experts say it can be exploited for another 200 years. Ecological restoration has been underway in the past decades, with over 26 square kilometers of mined lands restored.
