巢湖清溪煤矿煤岩石学特征研究
首发时间:2014-03-11
摘要:本文主要对巢湖市清溪煤矿煤样进行研究,论述了五通组岩性特征,并且发现煤层成煤植物主要为蕨类植物,并对煤样岩石学特征进行分析研究。研究发现煤样的显微组分主要以镜质组为主,具有较高含量的黄铁矿及粘土矿物,通过对煤样的煤岩组分统计和镜质组反射率的测定,发现煤变质程度较高,认为五通组煤样主要为变质程度高的无烟煤。

The Research of Coal features in Petrology from Qingxi Colliery in Chaohu.
Abstract:It is researched that the coal sample of qingxi colliery in this paper in Chaohu which is discussed the lithology of Wutong formation, coal forming plants being mainly Pteridophyta and Coal features in Petrology. It was found that the coal maceral is mainly vitrinite and also has more iron pyrite and clay mineral. It indicates that the coal sample of qingxi colliery has a higer metamorphic grade through the coal maceral statisticsed and the maximal vitrinite reflectance determined, which can draw a conclusion that the coal is belonging to anthracite.
Keywords: qingxi colliery coal forming plants coal maceral maximal vitrinite reflectance
