Microstructure research of Luning coal
WANG Xiu-ping
Abstract：Combining with the coal quality characteristics,the morphological analysis,atomic surface scan and surface structure analysis using scanning electron microscope were done for Luning coal.From the result we can see that:Luning coal is low sulfur,low ash,medium-high volatile matter,especially high calorific value and medium-relatively high caking property coal;mineral substance in coal is mainly the claymineral,main components are the Al and Si;the surface of the coal has no cracks and holes,the fracture is obviously the plant chamaesiphon fuscus structure,which means that the metamorphism degree of Luning coal is relatively low;the coal all has some heteroatom group and aromatic compounds.
