摘　　要：为了促进煤炭更好地分类加工利用,以达到降本增效的目的,通过对不同黏结指数下的试验煤样进行奥阿膨胀计试验研究,分析在不同黏结指数下各个试验结果的变化规律。研究结果表明:随着试验煤样黏结指数的增大,最大膨胀度逐渐变大;最大收缩度有所变化,但不明显;各个温度均呈下降趋势。In order to promote the better classification,processing and utilization of coal,in order to achieve the purpose of reducing cost and increasing efficiency.Through the experimental study of Oa Dilatometer on the test coal samples under different bonding index,the change law of each test result under different bonding index is analyzed.The results show that with the increase of the adhesion index of the tested coal samples,the maximum expansion degree gradually increases,the maximum shrinkage changes,but not obvious,and each temperature shows a downward trend.
