Coal mine gob area sealing method

The invention discloses a coal mine gob area sealing method, and belongs to the technical field of coal mine gob area gas extraction. When retaining walls of a first sealing chamber or roadway surrounding rocks between the retaining walls are cracked, cracks can be rapidly filled by the aid of fine sand with flowability under the action of ground stress and mining dynamic stress, and tightness is ensured. By the aid of positive and negative differential pressure characteristics of a second sealing chamber, nitrogen pressure in the second sealing chamber is constantly higher than air pressure in a ventilating roadway, a gob area is separated from the ventilating roadway by the second sealing chamber, air in the ventilating roadway cannot enter the gob area, and gas in the gob area cannot permeate into the ventilating roadway. By double sealing of the first sealing chamber and the second sealing chamber, sealing reliability of the gob area is greatly improved, the probabilities of spontaneous combustion of float coal and gas explosion are minimized, and safety of nearby roadways or working faces is guaranteed.
