The invention discloses a furnace brick patching method of an oxygen enrichment top-blown copper metallurgical furnace, and belongs to the technical field of metallurgical and smelting furnaces. According to the furnace brick patching method, a method that broken furnace bricks are patched outside the furnace, and a reinforcing rib plate is used for reinforcing and balancing is adopted. The furnace brick patching method includes the steps of firstly, observing a brick falling range inside the furnace through a material inlet, then determining the accurate brick falling position through temperature measurement outside the furnace, welding the reinforcing rib plate on the brick falling position of a furnace shell, cutting a section of the furnace shell along the inner side of the reinforcing rib plate, measuring the furnace brick thickness at the position of a cutting opening, determining the vertical range of furnace brick patching, carrying out upward construction in the center of the cutting opening from the datum plane to the vertex where patching is required, finally, adopting the method that disassembly is carried out while construction is carried out to carry out patching to the two sides until the whole region required to be patched is completely patched. The furnace brick patching method has the advantages of being simple, easy to achieve, simple in structure, convenient to assemble and operate, low in investment cost, safe, practical, capable of effectively improving the oxygen enrichment top-blown copper metallurgical furnace furnace-brick patching efficiency, capable of remarkably prolonging the service life of the oxygen enrichment top-blown copper metallurgical furnace and widely suitable for the oxygen enrichment top-blown copper metallurgical industry.
