“…According to the Monte Carlo method, Li et al 18 studied the relationship between adsorption thermodynamic parameters. Abunowara et al 19,20 CO 2 is one of the effective means to solve the problem of coal spontaneous combustion in goaf because of its large ratio, high adsorption performance of coal, and strong inerting effect. 22 The global storage capacity of coal seams for CO 2 ranges from 89.1 to 269.0 trillion cubic meters, and both goaf and coal seams with low utilization value can be used as CO 2 storage reservoirs.…”

The utilization of CO2 is extremely important to solve the environmental problems and coal spontaneous combustion in goaf. There are three kinds of CO2 utilization in goaf: adsorption, diffusion, and seepage. Since adsorption will consume CO2 in goaf, the optimization of CO2 injection amount is very critical. A self-developed adsorption experimental device was used to determine the CO2 adsorption capacity of three different particle sizes of lignite coal samples at 30–60 °C and 0.1–0.7 MPa. The factors affecting CO2 adsorption by coal and its thermal effect were studied. In the coal and CO2 system, the CO2 adsorption characteristic curve is not affected by temperature, but there are differences in that with different particle sizes. The adsorption capacity increases with the increase of pressure, while it decreases with the increase of temperature and particle size. Under atmospheric pressure, the adsorption capacity of coal is a logistic function relationship with temperature. Furthermore, the average adsorption heat of CO2 on lignite shows that the interaction force between CO2 molecules has a stronger effect on CO2 adsorption than the effect of heterogeneity and anisotropy on the coal surface. Finally, the existing gas injection equation is improved theoretically with CO2 dissipation, which provides a new idea for the work of CO2 prevention and fire suppression in goaf.
