Introduction. Open pit mining is defined as the method of extracting any near surface ore deposit using one or more horizontal benches to extract the ore while dumping overburden and tailings (waste) at a specified disposal site outside the final pit boundary. Open pit mining is used for the extraction of both metallic and nonme-tallic ores.

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.
