摘　　要：采用先施工导硐、后施工光爆层的二次成巷方案,通过合理地优化爆破设计以及多次对现场光面爆破方案进行总结和完善,使得光面爆破在三山岛金矿辅助斜坡道施工中得到成功的应用,提高了斜坡道施工进度,确保了该矿资源开采的安全性。Assistant ramps of Sanshandao gold mine were completed by two times blasting which pilot tunnel was blasted for the first time and smooth blasting layer was blasted for the second time. Through reasonable optimization of blasting design and summarizing and improving the smooth blasting scheme by multiple field tests, the scheme has been successfully applied in the construction of ramps. This improvcs construction speed of ramps and ensures mining safety.
