Abstract: In the later stage of coal formation, coal-bearing rock measures experience multi-stage tectonic movement, and coal and rock body has varying degrees of damage deformation, which results in differences in coal seam gas, permeability and physical and mechanical properties. That directly affects the selection of coalbed methane development process and the implementation of gas extraction technology. Based on the analysis of mine coal field exploration and actual production data, combined with laboratory tests and downhole survey, this paper discusses the geothermal characteristics of coalbed methane in Zhongmacun Coal Mine. Results show that reservoir has characteristics of occurrence stability, large thickness, high gas content, poor permeability, soft and hard interbed of coal structure and wide distribution of abnormal high pressure reservoirs. The gas content and its distribution characteristics of coalbed methane are controlled by hydrocarbon evolution and tectonic and closed conditions during geological evolution. Burial history of the coal seam has gone through five stages. The settlement of the Neogene has made the theoretical gas content increased, which is beneficial to the enrichment of coalbed methane. Gas content of coalbed methane is obviously controlled by faults, and there are high contents in the vicinity of compressive torsional faults and closed faults, and these areas are also coal and gas outburst areas; the open roof is low in the vicinity of open fault, and direct roof lithology of coal seam is mudstone and sandy mud, which provides favorable conditions for the storage of coalbed methane.
