In order to explore potential resource of coalbed methane in Xinji coal deposit of Huainan coalfield
its tectone-thermal evolution history was studied by using fission track technique. The results showed that there had been 3 or more times of significant thermal events occurred in this area since the late Palenzoic Era. The paleo-geothermal gradient was higher than that of the present. It was estimated that the denudation thickness in this area should be over 2000m. Mainly formed between 240-140Ma
no abundant methane could be generated in such condition. Furthermore
the tectone-thermal events would release the most of methane gases. So
the potential resource of the coalbed methane in this are might be limited.
