  • Using experiment and formula method, this study calculated mixing proportion of thermogenic gases and secondary biogenic gases, and evaluated resources significance of secondary biogenic gases in Huainan coalfield. The result showed that mixing proportion is accordant by two different methods. The content of secondary biogenic gases is large in coalbed gases. the distribution range is from 43% to 79％. Moreover, the research results of domestic and oversea show that the generation of secondary biogenic gases increases gas content of coalbed. Therefore, the contribution of secondary biogenic gases is great for coalbed gases resources in Huainan coalfield.

Abstract: Using experiment and formula method, this study calculated mixing proportion of thermogenic gases and secondary biogenic gases, and evaluated resources significance of secondary biogenic gases in Huainan coalfield. The result showed that mixing proportion is accordant by two different methods. The content of secondary biogenic gases is large in coalbed gases. the distribution range is from 43% to 79％. Moreover, the research results of domestic and oversea show that the generation of secondary biogenic gases increases gas content of coalbed. Therefore, the contribution of secondary biogenic gases is great for coalbed gases resources in Huainan coalfield.
