摘要
104国道马鞍山路堑开挖中深孔控制爆破工程中,针对其复杂的爆破环境,采用预裂爆破、孔内分层微差与孔间微差等爆破技术,确保边坡稳定及周围环境的安全,取得了预想的爆破效果。
Giver the complicated surroundings Qround the explosion area,some blasting techuologies have been applied in the excavation of rock cut at 104 Nation of Highway in Ma′anshan avea.These techaologies include presplit blasting,slicing Millisecond blasting in the holes,millisecond blasting befween the holes.The explosion was carried out as expected,with no damage to both blasting slope and surroundings.
