　　It is a long-debated issue if there is a chemical structure change and gas generation during coal deformation and if so,what is the mechanism of gas generation.In our work,sub-high-temperature and sub-high-pressure deformation experiments were performed on middle-rank coal,and during the experiments,we exclude the impact of the residual gas in coals and the process of pyrolysis.
