| Abstract: | The petrographic research on coal seam No.2 -2 from Daliuta district,Shenfu area of North Shaanxi shows that the coal macerals are dominated by vitrinite and fusinite.The clay and quartz are the main minerals.The main microlithotype is bimacerite and the macrolithotypes are dominated by semidull coal and semibright coal.The exinite has strong fluorescence,which characterizes by single peak.But,different kinds of exinite have different fluorescence characteristics. |
