【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更多还原

【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.更多还原
