Effects of CO2–water interaction with coal on mineral content and pore characteristics

There are a large number of abandoned coalmines in China, and most of them are located around major coal-fired power stations, which are the largest emission sources of carbon dioxide (CO2). Considering the injection of CO2 into abandoned coalmines, which are usually in the flooded condition, it is necessary to investigate the effect of CO2–water–coal interaction on minerals and pore structures at different pressures, temperatures and times. It...
