摘　　要：为了了解神东气化用煤在不同灰分情况下其它煤质指标的变化情况,通过采取不同厚度煤层的底板岩石样与原煤样进行配比试验,找出其煤质变化规律,以供煤气化实际生产参考。In order to obtain the variation regulations of other quality index on different ash yield condition for Shendong gasifying coal, the matching experiments were carried on, by blend coal samples with understratum rock samples with different seem thickness, to find out coal quality variation regulations and provide the actual gasification industry will references.

关 键 词：气化用煤 煤质指标 灰熔融性 灰成分
