摘　　要：针对开滦矿区煤泥细泥含量高的问题,采用两种捕收剂、三种起泡剂进行了单因素浮选试验。试验结果表明,药剂种类和用量对浮选效果影响显著,煤油和仲辛醇的组合效果最好;选择捕收剂用量、起泡剂用量及充气量进行三因素三水平正交试验,结果表明,在试验范围内充气量对浮选效果影响最显著。According to high content of fine slime in coal slurry in kailuan mining area,the single factor experiments were conducted with two kinds of collector and four kinds of frother.The result shows that type of reagent and adding quantity has remarkable influence on flotation result,especially the combination of kerosene and 2-octyl alcohol is best,and then,the orthogonal test was done with three factors（collector amount,foaming agent amount and quantity of aeration） and at three levels.The results showed that quantity of aeration was the main influence factor on flotation.
