We propose an experimental adsorption device, imitating the environment of a coal-mine goaf and the composition of the flue gas in Tashan Mine Power Plant. The characteristics of the coal adsorbing flue gas were studied with the atmospheric volumetric method. The factors affecting the seal of CO2 were analyzed and the effect of power plant flue gas on fire prevention in the goaf was investigated at normal temperature and pressure. It can be inferred from the experiment that N2, SO2, and H2O can also reduce CO2 adsorption capacity. The increase or decrease in pH can increase the adsorption capacity of CO2, which is apparently larger when the pH is decreasing than when the pH is increasing. The O2 adsorption capacity can evidently be reduced when the power plant flue gas is injected into the goaf. The activation energy of coal burned in air is greater than that of coal burned in flue gas, indicating that the use of power plant flue gas, with N2 and CO2 as the main components, to replace the traditional inert gas can not only save N2 generation cost, but also reduce the emission of greenhouse gases, while the power plant flue gas can be adsorbed by coal.
