## 1 Introduction  
Since the industrial revolution, human activity has resulted in upraising the concentrations of greenhouse gases, causing an anthropogenic influence on global warming and climate change. If no reduction measures are taken, the global atmospheric temperature will rise by more than 1.5 \({}^{\circ}\)C and 2 \({}^{\circ}\)C by 2030 and 2050, respectively, according to the global average annual rate of anthropogenic CO2 emissions from 2011 to 2020 (38.9 billion tons CO2/year) [1]. Environmental repercussions of global climate change brought on by rising human-caused emissions of heat-trapping greenhouse gases are already ubiquitous, such as accelerated sea level rise, sea ice loss, melting glaciers and ice sheets, more intense heat waves, and plant and animal geographic ranges shifts. Human-caused global climate change is irreversible and will worsen in the coming decades [2]. There is almost a universal agreement that the world cannot sit back and wait for definitive answers on this issue, and that preventive and mitigating measures must be implemented concurrently. CO2 is recognized as by far the most significant greenhouse gas due to its relative abundance when compared to the other greenhouse gases, accounting for around 64% of the heightened\"greenhouse effect\". Therefore, reducing CO\({}_{2}\) emissions to the atmosphere is a significant challenge in mitigating anthropogenic effects on climate change. Currently, heavy energy-consuming sectors are moving to developing nations [3], which results in the rising phase of CO\({}_{2}\) emissions in developing countries. The CO\({}_{2}\) emission reduction at the expense of reducing the amount of industrial activity harms economic development, generating two competing demands to keep both economic growth and substantial CO\({}_{2}\) emission reduction for developing countries, especially for China, the major developing country in the world [4]. Carbon Capture, Utilization and Storage (CCUS), as one pathway to carbon neutrality goals, can meet these two competing needs. Nowadays, more than 100 countries have proposed corresponding carbon neutrality programs. According to the prediction of existing research, fossil energy will still play an important role by 2050, and Carbon Capture, Utilization, and Storage (CCUS) is the only technical choice to achieve large-scale zero-emission utilization of fossil energy [5]. CO\({}_{2}\) enhanced coabled methane recovery (CO\({}_{2}\)-ECBM) is an important technical approach of CCUS, which has the dual benefits of greenhouse gas emission reduction and clean fossil energy recovery [6]. Within the coal matrix, the adsorption capacity of CO\({}_{2}\) is higher than that of CH\({}_{4}\) so that CO\({}_{2}\) can replace most of the originally adsorbed CH\({}_{4}\). Thus, the latter is desorbed and swept out. Simultaneously, along the run-through cleats and cracks in coal, CO\({}_{2}\) injection can maintain reservoir energy by improved pressure gradient so that the partial pressure of CH\({}_{4}\) is relatively compensated. CO\({}_{2}\) storage mechanism and storage capacity, and the effect of increasing production of CH\({}_{4}\) are the key technical problems of CO\({}_{2}\)-ECBM [7]. At present, CO\({}_{2}\)-ECBM technology is not very mature, and it is still in the pilot test or experimental mining stage in the world, and has not achieved large-scale commercial mining appraisal. Table 1 illustrates the existing CO\({}_{2}\)-ECBM field experiments and their details. It can be seen from Table 1 that the permeability of coal seams in the United States, Canada and other countries are better, which is one to two orders of magnitude higher than that of Chinese coal. In addition, due to the good adsorption of high-rank coal, most of the experiments are based on middle and high-rank coal seams, and there are few experiments on shallow low-rank coal.
