摘　　要：本文采用透射电子显微镜观察、x射线粉晶行射分析、差热分析和其他常规方法,结合化学分析等手段进行综合研究,发现晋中柳湾煤矿的主采煤层之一——11煤层的4层夹矸均为质量很好的硬质粘土岩,可供煤矿开采利用,是有价值的粘土矿资源。Adopting transmission electron microscope. X-diffraction analysis of powder crystal, differential thermal analysis, chemical analysis and other conventional methods, this paper makes a synthetic study on 4 clay bands deposited in No.1 1 coal seams., one of main-mining seams in Liuwan Mine. Shanxi province. The authors find out that they are all hard clay rock with high quality, which can be mined. So the clay bands are valuable resources of clay ore.
