摘　　要：光面爆破技术是隧道工程中广泛使用的施工技术。为了选择合理的光面爆破施工参数,通过岩石抗压强度、钻孔直径、药卷直径、爆破器材的性质等参数的配比计算,得出了合理的光面爆破孔距及装药参数。结果表明:该参数方案可以有效提高周边孔的炮孔利用率和光面爆破效果,该公式对硬岩中光面爆破参数选择具有参考价值。The smooth blasting technology is widely used in the construction of tunnel engineering. In order to select reasonable smooth blasting construction parameters, reasonable smooth blasting hole spacing and loading parameters were obtained through calculation of rock compression strength, drilling diameter, roll diameter and properties of blasting materials.The results show that the parameter scheme can effectively improve the borehole utilization and smooth blasting effect of the surrounding holes, which is of reference value to the selection of smooth blasting parameters in hard rock.
