The invention relates to a strip mine blasting slag stopping barrel structure and an optimization method thereof, the strip mine blasting slag stopping barrel structure comprises a cylindrical slag stopping barrel, at least one lateral hole is formed in the side face of the cylindrical slag stopping barrel, and the lateral holes of the cylindrical slag stopping barrel are evenly distributed in the radial direction of the cylindrical slag stopping barrel or distributed in the axial interval increasing mode. The optimization method comprises the following steps of (1) determining the optimal shape of the lateral opening hole structure of the cylindrical slag stopping barrel, (2) determining the optimal distribution form of the lateral opening holes of the slag stopping barrel, (3) determining the lateral opening area of the cylindrical slag stopping barrel according to a lateral opening coefficient calculation model of the cylindrical slag stopping barrel, (4) establishing a blast hole single-hole blasting nume
