Abstract: Combining with the actual geological conditions in Pingshuo East Open-pit Mine, the mine builds the inner dumping mode of half pressing slope, analyzes the transportation cost and re-stripping cost when the 4# and 9# coal using half pressing slope inner dumping mining, and obtains that two ways in the economy are better than the whole pressing slope, and presents all the 9# coal mining ditch program.
