Abstract: Coal mining causes the pressure releasing from coal reservoir,the coal reservoir parameters' great changing,and has the enormous influence on the coalbed methane storage and the migration. The experiment achievement of Luling coal mine,concerning ground well drainage from pressure release area and related ground well and underground well integrated drainage technology,indicated that the coalbed methane drainage from coal seams with low permeability in the release area of pressure is not only an advantageous to the coal mine safety production,but also can enhance recovery ratio of the coalbed methane enormously and enhances the economic efficiency of the coalbed methane development.
