Abstract: Geological storage of carbon dioxide as a greenhouse mitigation method, attracted
widespread the attention of experts and scholars at home and abroad. Coal enhanced coalbed
methane can reduce greenhouse gas emission and improve the coalbed methane recovery. Firstly
the principle of CO2-ECBM and sequestration technology progress and analysis of domestic and
foreign studies were introduced; then the analysis of various factors on the development trend of
the coal seam sequestration of carbon dioxide was proposed and research directions are suggested.
It can provide theoretical and technical support for improving CBM recovery and CO2 long-term
safety of geological storage .
