摘要
利用深孔松动控制爆破技术对复杂环境下拓宽路段山体进行爆破开挖。根据工程特点 ,通过优化深孔松动爆破参数和光面爆破参数 ,选定适宜的松动作用方向 ,采用闭合双回路孔内外延期非电微差起爆技术 ,严格控制最大一段起爆药量 ,并采取有效的安全技术措施 ,爆破达到了预期效果 。
WT5”B1]:The aplication of deephole loosening controlled blasting under complicate environment at Xuehuashan Section of shengli road in Bengbu City is introduced. According to the characteristics and environment of this engineering project thorugh optimumly selected appreciative parameters of loosening blasting and slope smooth blasting, using a closed blasting network of in hole and out hole millisecond delay,controlling the every delayed detonating change and taking effective safety operations,the blasted flying rocks and blasting vibration have been controlled successfully.
