The invention discloses a method for comprehensively dealing with the situation of corner gas overrun of a working face. The method for comprehensively dealing with the situation of corner gas overrun of the working face comprises the extraction step, the leakage control step, the dilution step and the roof caving step, wherein the means that split-source collaborative extraction is carried out on gas in a goaf, goaf air leakage control and dilution of gas in the air return corner are carried out when gas in the goaf normally flows out, and forced roof caving is carried out when the gas in the goaf suddenly flows out are adopted. The gas overrun, caused by normal flow and normal flow of the gas of the goaf, of a ventilation system of the working face can be comprehensively dealt with, safe and efficient production of a mine is ensured.
