贵州省六盘水黑塘井田煤层煤质特征分析

Analysis on coal quality characteristics of Liupanshui Heitang coal mine in Guizhou province

为合理利用黑塘井田煤及更好地保障贵州省内的煤炭供应,基于黑塘井田概况及化验资料对井田煤层煤质特征进行分析,确定了黑塘井煤的工艺性能、煤类和工业用途。结果表明:井田煤宏观煤岩类型多以暗煤为主,有机显微组分主要为镜质组和惰质组,偶见壳质组;属于中-中高灰、低挥发分、中等固定碳、中高-高硫、中-中高发热量的贫煤及贫瘦煤;煤的主要用途为火力发电、其它动力用煤、民用煤、气化用煤等。

In order to make economical utilization of the coal in Heitang mine field,and better to secure the coal supply including electric coal to Guizhou province,the coal quality was analyzed based on general characteristics and experimental data.The process performance,coal rank and industrial utilization of coal were determined.The results showed that dark coal is the main lithotype of the mining area coal.Organic maceral was mainly the vitrinite and inert group,occasional exinite;The coal belongs to medium-medium high ash,low volatile,medium fixed carbon,medium-medium high calorific value and meager-lean coal;the main use of coal are thermal power,power coal,civil coal and gasification.
