Adsorptive charateristics and controlling factors of coal seams in TU-Ha basin

The research on adsorptive characteristics and controlling factors of coal seams in Tu-Ha basin indicated that the methane adsorptive capacity is still strong,although the rank of coal seams are relatively low,which is the major controlling factor for adsorptive capacity of coal seams.The other factors,such as maceral components,moisture content and oil-bearing property,have also different degree of influence.
