Based on previous measured data and adsorption isotherms experiment of six coal samples from different stratification of the southern Qinshui basin, discussed the diversity between different stratification on adsorption characteristics and its main controlling factors. The results show that: In the macro level, bright coal layer has the highest adsorption capacity, Langmuir volume (VL) is up to 40m3/t ; the adsorption capacity of dull coal and semi-dull coal is relatively low. By analyzing the relationship between the Langmuir volume of coal petrography and various factors, discovering the Langmuir volume has a positive correlation with vitrinite content, vitrinite reflectance, fixed carbon content, and micro-pores content, but negative correlation with ash, while it has no significant linear relationship between moisture, porosity, permeability. By grey relational analysis, it shows that the impact is in descending order from vitrinite content to fixed carbon content, vitrinite reflectance, micro-pores content, ash content.
