隆尧县丰达煤矿2号煤层煤质特征分析及评价

Analysis and evaluation of coal quality characteristics of No.2 coal seam in FengDa Mine

介绍了隆尧县丰达煤矿地质背景和全区主要可采煤层2号煤的基本情况。分析了煤层的煤岩特性,宏观煤岩类型多为半暗—暗淡型煤;有机显微煤岩类型以镜质组为主,矿物主要由黏土组成。煤质分析表明,原煤属中灰、中高挥发分、低硫、低磷、特低氟、低氯煤;煤层为气煤,属中高发热量、强黏结性、易选煤。通过研究煤质特征,发现2号煤层用途广泛,主要用作炼焦用煤、气化用煤和动力用煤。

The geological background of Fengda Mine in Longyan County and the basic situation of No.2 coal seam of the main recoverable coal seams in the whole district were introduced.The coal and rock characteristics of the coal seam were analyzed.The macroscopic coal rock types were mostly semi-dark-dark coal;the organic micro-coal type was mainly vitrinite,the mineral mainly composed of clay.The coal quality analysis showed that the raw coal was medium ash,medium and high volatile,low sulfur,low phosphorus,ultra low fluorine and low chlorine coal;the coal seam as gas coal,belongs to medium and high calorific value,strong cohesiveness and easy coal preparation.By studying the characteristics of coal quality,it was found that No.2 coal seam was widely used for coal for coking,gasification and power.
