介绍一种改进型的边坡缓冲孔爆破工艺。采用分段间隔式装药结构 ,且无超深 ;孔距约为正常生产炮孔孔距的 0 7倍 ,并以 2～ 3个孔为一组滞后于相邻前排孔 5 0～ 10 0ms起爆。实测数据表明 ,该工艺能减少后冲破坏 ,降低爆破近区的震动
An improved slope buffer hole blasting process is introduced. Using sub-interval charge structure, and no ultra-deep; hole spacing is about 07 times the normal production hole distance, and 2 to 3 holes as a group behind the adjacent front hole 50 ~ 10 0ms explosion. The measured data show that the process can reduce the backhoe damage and reduce the blast near the vibration
