Study on the diffusion and migration law of CO2 sequestrated in abandoned coal mine goaf

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 530-547, December 2025.
The goaf of an abandoned coal mine, endowed with expansive fracture spaces and an abundance of residual coal, can be capable of sequestrating substantial quantities of CO2. The residual coal is the principal medium for the sequestration of CO2 in the form of adsorption and the amount of sequestration is considerable.
