Last year, the country produced 283 million tons of lignite, stripped 1.3 billion m 3, and drained 1.7 billion m 3. The output of lignite ranks first in the world, accounting for 30% of the world’s total output. According to the different geological conditions of lignite deposits in their own country, they adopt a variety of continuous open-pit mining processes. Dumping bridge is currently used straight
