摘要
基于为石上井田煤层合理利用途径提供一定指导依据,介绍了石上井田主要可采煤层B4、B3煤层特征及宏观煤岩特征。通过各煤层样品测试成果对其显微煤岩特征、煤质特征进行分析,结果表明:B4煤层为特低全水分、中高灰分、中硫分、低挥发分、中高发热量煤,煤类属焦煤(15号);B3为特低全水分、中高灰分、中硫分、中等挥发分、中发热量煤,煤类属焦煤(25号)。煤的可选性为难选,B4、B3煤层可作为焦煤用煤、火力发电厂及其他动力用煤。
Based on the rational utilization of coal seam in the stone upper mine field,the characteristics of coal seam B4 and B3 and the macroscopic characteristics of coal and rock in the Shishang mine field are introduced.Through the analysis of the micro-coal and rock characteristics and coal quality characteristics of each coal seam,the results show that the B4 coal seam is coal with extremely low total water content,medium high ash content,medium sulfur content,low volatile content and medium high calorific value,and the coal belongs to coking coal(No.15).B3 is the coal with extra low total water content,medium high ash content,medium sulfur content,medium volatile content and medium calorific value.The coal belongs to coking coal(No.25).The selectivity of coal is difficult to choose,B4 and B3 coal seams can be used as coking coal,thermal power plant and other power coal.
