摘　　要：根据单种煤的镜质体反射率实测分布图,按照直方图的合成原理,统计出各反射率区间的频率,制定出人工合成配合煤镜质体反射率分布图的方法。此方法可以方便地计算出多种煤不同配比时的镜质体反射率平均值(■)和标准差(S),并绘制出配合煤的镜质体反射率分布图,减少了复杂的化验过程和高昂的化验费用,在选煤和配煤方面具有很好的推广利用价值。This paper shows the frequency of each reflectance interval and the method of generating a vitrinite reflectivity distribution chart of mixed coal based on histogram generation principles and the vitrinite reflectivity distribution of single coal.It calculates average vitrinite reflectance(■)and standard deviations(S)of mixed coal under different ratios and generates a vitrinite reflectivity distribution chart so to save time and cost of laboratory work,which could be widely applied in coal blending and coking-coal mixing process.
