The invention belongs to the technical field of metallurgy and discloses a side-blowing material-smelting production method. The side-blowing material-smelting production method comprises the following steps of: 1) building a furnace hearth, and 2) normally smelting materials: forming a mixed material by adopting lead zinc paragenic ore and zinc leaching slag at any proportion; uniformly adding the mixed material, limestone and powdered coal within 30-60min under the conditions of temperature at 1000-1300 DEG C and excess air coefficient below 0.8-1.0, wherein the percentage of the powdered coal is 25-35% and SiO2/CaO=1/(1.5-2) of slag is controlled by the dosage of the limestone; after completely adding the materials, adjusting coal feeding volume and blast volume, thereby adjusting the excess air coefficient to be 0.7-0.9; after smelting the materials for 30-60min, reducing the lead in the materials to lead bullion, zinc and other components, thereby forming smelted slag; and after finishing material smelti
