摘要
介绍了高家庄井田可采和局部可采煤层的基本情况。分析了煤层赋存状况,物理、化学特征和煤岩特征,说明井田煤层为中变质煤,硬度小,脆度大;宏观煤岩类型以光亮型煤、半亮型煤为主,其次为半暗型、暗淡型煤。煤层有机组分以均质镜质体、基质镜质体为主,其次是结构镜质体和碎屑镜质体,胶质镜质体、团块镜质体少见;煤层中无机组分以黏土矿物为主,其次是黄铁矿类和碳酸盐类。2,4号煤层属中等挥发分、中等可选焦煤;8,9+10号煤层属低等挥发分、易选焦煤和瘦煤。最后论述了高家庄井田煤层的工业用途。井田内煤属炼焦用煤,主要用来炼焦,也可作为动力及化工用煤。2,4号煤层可单独炼出Ⅰ级冶金焦,8,9+10号煤层除硫降磷后,采用合理配煤工艺,亦能炼出优质冶金焦。
Introduce the basic information of minable coal seams and local ruinable coal seams Of Gaojiazhuang underground mine field. The analysis of coal seam occurrence condition, physical, chemical characteristics and coal lithotypes show that the coal seams are medium rank coal which has low hardness and high brittleness. The main macroscopic coal types are vitrain and semibright coal, then dnrain and semidnll coal. The main organic components are telocollinite and desmocollinite, followed by telinite, vitrodetrinite. Gelocollinite and corpocollinite are rare. The main inorganic components are clay minerals, followed by pyrite and carbonate. The NO. 2 and NO. 4 coal seam are medium volatile, medium optional coking coal which can smelt level 1 metallurgical coke. The NO. 8 and NO. 9＋10 coal seam are low volatile, easy separating coking coal and lean coal which can smelt high quality metallurgical coke through reasonable coal blending after removing sulfur and phosphorus. The analysis of industrial application of underground mine field indicates that, the coal is mainly used for coking, also for power generation and chemical industry.
