Abstract
A large sum of gas desorption results from different coal rank and different age coals in China, measured under reservoir temperature and atmospheric pressure, are systematically researched. And gas desorption regularities and variation patter of gas desorption parameters during gas desorption processes are analyzed, as well as the gas desorption characteristics of coal seams in China are discussed, providing basic theoretical foundation for improving coalbed gas production rate.
