The invention discloses a local repairing method for a blast furnace hot blast stove vault. The method comprises the steps that for each layer in a to-be-repaired area of a hot blast stove vault refractory lining, a bottom-to-top building manner is adopted in a traditional bricking method area, refractory bricks are integrally built till the final door closing position; a building manner from two sides to the top is adopted in the repairing areas on the two sides of the final door closing position till the topmost furnace inner original brick area, and a door closing area where door closing can be carried out on the outer ring is reserved; a building manner from top to bottom is adopted, and the door closing area is built; and door closing bricks are built at the final door closing position. Under the situation that the quality is guaranteed, the repairing processing workload is reduced.
