The results indicate the adsorbability of coal in the region is relatively low, and increasing with vitrinite reflectance and decreasing with moisture in raw coal. It is probably related with micropore characteristics of coal.

• 测试结果表明中低变质煤的吸附能力普遍较低 ,且吸附能力随煤镜质组反射率值的增加而增加 ,随煤中水分的增加而减小 ,其原因与煤的微孔特征有关。
