平朔东露天矿半压帮内排开采程序研究

Research on half pressing slope inner dumping mining process in Pingshuo East Open-pit Mine

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。

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.
