PURPOSE: Coal briquette for a long-term storage, and a manufacturing method thereof are provided to keep coal briquette for a long term by solving a problem due to oxidation and decay of oil. CONSTITUTION: A manufacturing method of coal briquette for a long-term storage comprises the steps of: preparing a liquid adhesive by mixing 100wt% of a fatty acid condensation resin, and 0.005-0.02wt% of tocopherol; spraying 3-10wt% of the liquid adhesive to 100wt% of pulverized coal; mixing the sprayed liquid adhesive and the pulverized coal uniformly; and pressure-molding the outcome at room temperature. The fatty acid condensation resin is condensation-manufactured by adding polybasic acid to polybasic alcohol group and oil group, and heating and ester-reacting them.
