Background: As an important energy source, coalbed gas (CBG) has been widely used. However, the allocation system of CBG resources is not perfect. During the utilization process, a large amount of CBG is discharged into the air, causing environmental pollutionMethods: In this study, we proposed a “full spectrum-domain-time” CBG utilization model, including full spectrum CBG utilization technology and full domain CBG supply, In addition, based on time series algorithms, real-time prediction of the demand for CBG, grasp the characteristics of time changes in demand, and scientifically allocate resources, that is, “full-time” regulation. Taking Yangquan Coal Group, Shanxi Province, China, as a case study, introduced the application of the “full spectrum-domain-time” utilization model in the enterprise, and at last assessed the achievement of the model application. Results and Conclusions: The time series algorithm can be used to predict CBG demand in different regions of the mining area. Driven by this model, both the total CBG and low-concentration CBG utilizations in the Yangquan Coal Group increase year after year, making it promising to reach 77.15% of CBG utilization rate and indicating that application of the model has made great accomplishment.
