基于层次分析法的露天矿薄煤层开采工艺

Open-pit Mine Thin Coal Seam Mining Technology Based on AHP

露天矿薄煤层开采工艺方式的选择关系到整个矿的原煤损失率、贫化率以及矿石块度等指标,直接影响到露天矿的经济效益。在研究影响薄煤层开采工艺的主要指标基础上,建立层次分析模型,并以哈尔乌素露天煤矿5#煤开采工艺为实例,论证结果的正确性。

Some indexes such as the loss rate and dilution rate of the coal and ore fragmentation are affected by the choice of thin coal seam mining technology in openpit mines, which directly influences the economic benefit in openpit mines. The AHP analyzing model was established based on researching the main indexes which influence thin coal seam mining technology. A case study was carried out by dealing with harwusu 5# coal mining system and the correctness was validated. The results have important guiding significance to the thin coal seam mining in similar mines.
