为探讨煤的煤岩学特征与焦炭强度之间的关系，对北京焦化厂所用华北地区２６个矿点的原料煤的煤岩学特征进行了研究，并对１０ｋｇ小焦炉焦炭的强度进行了测定。通过对Ｍ４０≥８０％矿点煤的统计分析，表明活性成分含量的最佳范围是６３４０％～６９４０％，镜质组平均反射率基本处于１１２％～１３６％之间。镜质组反射率分布图谱不仅可以直观地反映活性成分的大致分布状况，而且也可以反映原料煤的混合程度 In order to explore the relationship between coal petrology characteristics and coke strength, the coal petrology characteristics of raw coal in 26 coal mines in North China used by Beijing Coking Plant were studied, and the strength of coke in 10 kg coke oven was studied Determination. Through the statistical analysis of M40≥80% coal point coal, the best range of active ingredients content is 6340% ~ 6940%, the average reflectance of vitrinite is 112% ~ 136% between. Vitrinite reflectance distribution map can not only visually reflect the general distribution of the active ingredient, but also can reflect the degree of raw coal mixing
