The invention specifically provides a reinforcing method of mine freezing shaft cracks, and aims at solving the problem that the existing mine freezing shaft cracks influence safety construction. The reinforcing method of the mine freezing shaft cracks comprises the steps of a, filling permeable epoxy resin into a clearance in a concrete slotted wall and solidifying; b, arranging a plurality of vertically-arranged channel steel walling cribs on the walls at the shaft cracking sections, arranging threaded steel resin anchor bars to the wall to fix the channel steel walling cribs, and clinging and fixing the two adjacent channel steel walling cribs in the center of the cracks by a top to bottom manner; c, constructing a group of temporary bases in the stable surface soil at a certain distance; d, constructing the crack parts on the inner wall of the shaft, raising the grade of concrete for the inner walls of the wall section and an upper die and a lower die in the crack section. According to the reinforcing method, the safety of the wall structure and the overall completeness are achieved; the problem that the original wall is scraped is overcome; the safety construction of the wall is ensured; meanwhile, the reinforcing method is relatively high in economic benefit, simple in process, and convenient to operate.
