摘　　要：针对混煤的镜质体反射率直方图解读过程中出现的常见问题,分析了煤的镜质体反射率与煤种之间的关系,认为不同煤种的镜质体反射率有互相重叠之处,仅通过煤的镜质体反射率指标只能给出可能的煤种;解释了混煤判别中的单种煤比例与实际单种煤质量比例的关系,认为混煤判别中的单种煤比例确切应称之为混煤中单种煤的基质镜质体与均质镜质体的体积比。混煤判别只能定性给出,而混煤中单种煤质量占比不能准确定量得到。Regarding to the common questions in the histogram interpretation process of vitrinite reflectivity of mixed coal,the relationship between vitrinite reflectivity and coal species was analyzed, it was indicated that the vitrinite reflectivity of different kinds of coal have overlapping points,through the vitrinite reflectivity,the possible coal type can be only judged;the relationship between single type coal ratio and practical single type coal ratio in mixed coal judgement was demonstrated,the single type coal ratio in mixed coal judgement should be called the volumetric ratio of matrix vitrinite and homogenous vitrinite of single type coal in mixed coal.The mixed coal judgement could only be given qualitatively,and the single type coal weight in mixed coal could not be got quantitatively.
