摘 要
To comprehensively study the methane adsorption behaviour of coals under variable temperature and pressure, a series of methane adsorption measurements were conducted at different temperatures and pressures for different rank coals from Ordos Basin and Qinshui Basin. The results show that the methane adsorption capacity and temperature exhibit a negative linear correlation under the same pressure series. The combined effects of the temperature and pressure reveal that the high-rank coal has the maximum methane adsorption capacity and the low-rank coal owns the least. During the low pressure region, the increase of adsorption capacity of high-rank coal is the largest, whereas the low-rank coal has the least change with the temperature and pressure increasing. However, in the high pressure region, the decrease of adsorption capacity of high-rank coal is the least, and the low-rank coal owns the largest of that
