利用煤镜质组反射率分布图计算其镜质组含量

Calculating the Vitrinite Content by the Vitrinite Reflectance Distribution

将已知与未知镜质组含量的煤样按固定比例配制成混煤后测定其镜质组反射率,在得到的反射率分布图上,剥离出其中各单煤的反射率分布峰,依据峰面积之比推导出未知煤样的镜质组含量,即可在不增加测定工作量的情况下,同时得到测定煤的镜质组反射率数据与镜质组含量数据.目前这一方法仅限于测定煤为单煤的情况.

In our report,according to the fixed ratio,the known coal sample and unknown vitrinite content coal sample were blended,and then,the coal blending were measured to obtain the vitrinite reflectance. After peeling the reflectivity distribution peak of each single coal sample in the coal blending,based on the ratio of peak area,the vitrinite content of the unknown coal sample was calculated. Additionally,at the same time when measuring the vitrinite reflectance of the coal sample,the vitrinite content were also obtained.
