Abstract：According to the problems that the coalbed methane resource was rich in deep seam in China,but the economic and technology conditions were limited,it would be hard to mine with a conventional method.The CO2 capture,utilization and storage technology(CCUS) was provided.The application of the technology would not only improve the methane recovery ratio from deep and unmineable seam,but also put CO2 effectively in the deep seam for storage to reach a target of emission reduction.The study showed that a coal rank,coal seam pres-sure,coal seam permeability,injection time,injected gas types and others would affect to the recovery ratio of methane in a production mine.The cover layer,depth,structure development condition,earthquake activities and the underground water condition would also affect the storage of CO2 .Therefore,before the CCUS project implemented,a rational evaluation should be conducted on the place location in or-der to improve the feasibility of the project.
