摘要
根据煤岩学、煤化学与扫描电镜分析结果 ,研究了神东矿区 2 -2 # 煤的煤岩特征及主要性质 ,探讨了神东煤变质程度、显微组成 (包括矿物组成 )对其性质的影响 ,认为高含量的丝质组影响了其液化性能 ,而煤中相对含量较高的次生方解石影响了其煤灰熔融性 。
This paper presents the technical characteristics of 2 # coal seam in Shendong Jurassic coalfield based on the petrological,chemical and SEM study.The effects of petrological and metamorphic features of 2 # coal in its technical characteristics are discussed.The authors think that the high content of inertinite has lower liquefaction ability.the calcite,which is relative higher in content,affects the ash fusibility negatively.Both the blending technology and petrological preparation should be useful for improving the utilization of Shendong coal.
