摘　　要：通过对长时间堆放后不同变质程度肥煤粘结指数、胶质层指数、基氏流动度、奥亚膨胀度等指标的变化分析比较,结果表明,肥煤经长时间存放后,胶质层指数变化不明显,粘结指数、基氏流动度、奥亚膨胀度等性能指标呈下降趋势,不同温度下的流动度整体向低温区移动,且变质程度越低,下降幅度越大。肥煤经长期周转、运输后,应检测流动度、膨胀度指标,确定能否继续发挥肥煤作用,在配煤炼焦中应合理应用。The caking index,plastometric indices,Gieseler fluidity,Arnu-Audibert＇s dilatometer of different fat coal after long time storage were studied. The result showed that plastometric indices were without obvious change,and caking index,Gieseler fluidity,Arnu-Audibert＇s dilatometer descended,Gieseler fluidity under different temperature moved to lower temperature areas,the rank of fat coal was lower,and the descending range decreased more obviously after long storage time. After long- time turnaround and transport,Gieseler fluidity,Arnu- Audibert＇s dilatometer should be tested to make sure fat coal＇s function is well,and fat coal should be rationally blended.
