摘要(Abstract)：
介绍了柳州市柳石路鸡山工地复杂环境条件下高梯段深孔控制爆破技术。根据工程要求及环境特点，采用3～4排深孔及15排深孔一次起爆的爆破方案；通过选取合理的爆破参数，采用孔内孔外微差网格式闭合起爆网路，严格控制爆破飞石及爆破振动，使爆破工程取得了成功。
In this paper, a high bench longhole controlled blasting technology used under complicated environment at Jishan section of Liushi road in Liuzhou City is introduced. According to the characteristics and environment of this engineering, the controlled blasting scheme is that 3-4 rows of longholes as well as 15 rows of longholes are initiated simultaneously. Through selecting appreciate blasting parameters and using a closed blasting network of in-hole and out--hole millisecond delay, the fly rocks and blasting vibration have been controlled successfully.
