Abstract: Aiming at the reservoir and transportation characteristics of coal gas, a research idea that using electrochemical to strengthen coal gas desorption permeability and then to enhance gas drainage and drainage effect is proposed. The paper analyzes the coal gas desorption permeability mechanism which is strengthened by electromagnetic field and geoelectric field, and proposes the research method of using electrochemical to strengthen coal gas desorption permeability, and the feasibility is studied. This provides a basic theoretical foundation for strengthening desorption and permeability in coal-gas with electrochemical.
