| 摘 要： | 摘 要 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
M 40 ≥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。

| Abstract: | Based on the microscopic coal petrology study of some raw coal from 26 mining districts in North China and the measurement of coke intensity, the relationship between coal petrology and coke intensity is discussed in this paper. In order to obtain coke of high intensity ( M 40 ≥80%), the optimum percentage of active component ranges from 63 40% to 69 40%. The preferable value of mean vitrinite reflectance lies between 1 12% and 1 36%. Distribution diagram of vitrinite reflectance is very important for predicting the intensity of coke, because it not only can display the distributing state of vitrinite component but also can show us the degree of mixture of raw coal. |
