Ecological Reconstruction Research and Practice in the Large Open-Pit
Therefore, two thirds of the mines are mined by the open-pit mining mode. China is the world's largest coal producer and consumer. In 2015, the coal output in China is 3.75 billion tons, accounting for 47% of the world's total. However, most of the open-pit coal mines are distributed in the ecologically fragile areas of the Loess Plateau.
