This invention belongs to the field of gas control technology and relates to an integrated anti-blocking device and method for gas drainage boreholes, including a coal borehole wall support structure, a rock borehole section sealing structure, and a connector that fixes the two together. The coal borehole wall support structure includes multiple connecting pipes and at least one screen pipe arranged between the connecting pipes. Multiple metal supports are fixedly connected to the outside of the screen pipe. One end of the metal support is fixed to the screen pipe, and the other end is connected to the screen pipe through a second elastic element. Under normal conditions, the metal support is close to the screen pipe. The non-fixed end of the metal support is provided with a spherical buckle that is locked into the buckle opening of the screen pipe. A spherical top pin that can move axially is provided inside the screen pipe at the position corresponding to the spherical buckle.
