Abstract：According to theory of diffusion and permeation,and theory of adsorpt ion equilibrium of commixture gas，the mechanism of increasing coalbed methane production by gas injection is studied, with which it is illustrated for enhancing energy of storing gas stratum, heightening pressure conduction coefficient of storing gas stratum and binging domino effect of competition adsorption by gas injection, consequently yield and ratio of recovery of coal bed methane are also enhanced. The
calculation formulas of ratio of recovery are deduced. These conclusions have guidance significance to exploitation coalbed methane by gas injection.
