摘　　要：对勘探范围内毕节市王家坝井田的可采煤层地质储量进行了估算,并对C6-1和C7煤层进行了煤质特征分析与评价。研究表明,C6-1及C7煤层显微煤岩类型为微镜惰煤,显微矿化类型为微复矿质煤;C6-1煤层为中灰、中硫、高热值、特低挥发分、低磷、特低氯、一级砷高熔灰煤。C7煤层为低中灰、特低硫、特高热值、特低挥发分、特低磷、特低氯、一级砷高熔灰煤。煤类划分C6-1及C7煤层均属无烟煤三号,可广泛作为民用、化工、动力和火力发电用煤,其洗精煤可考虑供高炉喷吹用煤。The coal characteristics of C6-1,C7 coal-bed of Wangjiaba mine in Bijie City were analyzed and evaluated in this paper.The results showed： the coal maceral microscopic type of C6-1 and C7 coal beds are vitrinertite,and the microscopic mineralization type is carbopolyminerite;C6-1 coal bed is characterized as first grade arsenic high-fusion-ash coal with intermediate ash,intermediate sulfur,high calorific-value,extra-low volatile,low phosphorus and extra-low chlorine;while C7 coal bed is characterized as first grade arsenic high-fusion-ash coal with intermediate ash,extra-low sulfur,super-high calorific-value,extra-low volatile,extra-low phosphorus and extra-low chlorine.According to coal classification standard,both C6-1 and C7 are anthracite（WY3）,which can be used for combustion,chemical conversion and power generation,and the washed cleancoal can be used for blast furnace injection.
