Study on the Coal-Rock Storage of CO2 through Experiment

Abstract-The method of collecting storage has been widely regarded as a potential and alternative reduction plan of CO₂, which can keep a stable concentration of CO₂ in atmosphere and ease the climate change. In this paper, the fact that the coal-rock of mined area can realize the storage of CO₂ is verified through experiment, and the storage of CO₂ can prevent the self-igniting of coal in mined area. The adsorption experiment has been done by using the PVT equipment from Japan and the SII EXSTAR6000TG/DTG differential thermal weight analyzer, and the sample is from the DaTong tower hill diggings. The results of the experiment show that the storage volume of CO₂ can achieve 29000 tons by using the left coal and the volume can achieve 38320 tons by using the rocks falling from the crest slab, which can realize a win-win result of reducing the emissions of greenhouse gas and preventing the spontaneous of coal in mined area.
