摘要
煤类的划分一般是取样化验。对于煤层结构复杂、变质程度较高的煤类，定性分类较为复杂。利用测井资料所反映的煤层地球物理特征，结合岩芯地质描述、煤岩鉴定、煤质化验等资料，综合定性分类，效果良好。
The division of coal species is based generally on the sampling and analysis.As to the coal seams with complex texture and higher degree of metamorphism,the qualitative division of coal species is more complex.Using the geophysical characters of coal seams reflected by the logging data,combining with the data obtained from the geological description of cores,coalpetrologic identification and coal quality analysis and so on,the better effect is obtained in the comprehensive qualitative classification of coal species.
