Provided is a composition for the partial repair of a conveyor belt, which allows a belt damaged by impacts or torn by a sharp object to be repaired directly in the corresponding site with no need for disassembling the belt, and has adequate elasticity and hardness, high adhesion and toughness and fast-curing property. The composition for the partial repair of a conveyor belt is obtained by mixing: a mixed solution containing 25-35 wt% of a liquid urethane resin, 5-15 wt% of powder rubber and 55-70 wt% of rosin; and a rubber curing agent, in a weight ratio of 12:11-14:9. To perform the partial repair of a conveyor belt, a damaged portion of the conveyor belt is pre-treated, the composition is applied to the pre-treated portion, and then the portion is cured by heating it directly or indirectly at 70-90 deg.C for 5-15 minutes.
