对山西省长焰煤到无烟煤煤样进行了压汞试验,得到了不同煤级煤的比孔容/比表面积数据,并分析了比孔容/比表面积随煤级的分布变化规律。
Through the mercury injection experiment of long flame coal to anthracite coal sample in Shanxi province, this paper get the datas of volume ratio/surface area ratio of different rank coal, and analyse the volume ratio and surface area ratio with the change of coal rank.
