| Abstract: | The geochemical characteristics of coals from Liyazhuang coal mine, Sihe coal mine and Fucheng coal mine of Qinshui Basin, Shanxi Province, were comparatively studied, and the thermal evolution degree, the contents of soluble organic matter and the biomarker characteristics of coals were discussed. Based on this, the potential of thermogenic and secondary biogenic coalbed gases were analyzed and it is of practical significance for the coalbed gas exploration in the studied area. |
