岩相分析在混煤鉴别与控制中的应用

Application of Petrographic Analysis to Mixed Coal Identification and Control

介绍了焦化生产中常见的混煤形式及其对生产的不利影响，探讨了运用煤岩学手段鉴别和控制混煤的具体方法。

The mixed coal types often seen in coking production and theirunfavourable ef- fect on production are presented. The specific methods for identifying and controlling mixed coals with the coal lithofacies means are probed.
