神府大柳塔2^-2煤层煤岩学特征

摘要: 对神府大柳塔矿区2^-2煤层系统的煤岩学研究表明,该煤层以镜质体和丝质体为主,其它组分较少,矿物质中以粘土类和石英为主,显微煤岩类型以两组分微类型为主,宏观煤岩类型以半暗煤和半亮煤为主,壳质组具有较强的荧光,其荧光光谱为单峰形,不同的壳质组分其荧光特征不同。

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.
