平朔东露天矿半压帮内排开采程序研究

摘要

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.%结合平朔东露天矿的实际地质条件建立半压帮内排模型，对东露天矿4#与9#煤采取半压帮内排开采时运输费用与二次剥离费用进行分析，得出了两种方式在经济上较全压帮开采更优，提出将9#煤全部开采的留沟方案。
