刘小庙勘查区天然焦与无烟煤区分研究

摘要

刘小庙勘查区受燕山晚期闪长玢岩和辉绿岩侵入的影响，煤层变质为天然焦，通过对煤岩、煤质以及物性特征的分析，确定区分无烟煤与天然焦的主要方法。%Effected by the late Yanshanian diorite-porphyrite and diabase intrusion,the coal seam deteriorates into natural coke in the exploration area of Liu Xiaomiao.Based on the analysis of coal rock,coal quality and physical characteristics,the paper determined the main method of distinguishing anthracite coal and natural coke.
