摘要
在复杂环境下的深路堑石方爆破开挖中采用了高边坡控制爆破技术,根据工程特点,通过优化装药结构,采用孔内延时与孔外接力延时手段,减少了单响药量,降低爆破震动影响,取碍了良好的爆破效果。
The application of high slope controlled blasting under complicate environment is introduced to the deep expressway blasting construction. According to characteristics of the engineering project,the delay in holes and the relay delay outside the holes are used at the same time, which cuts down the single dose and effectively lower the blasting vibration. The optimization of the charging structure will also lead to successful blasting performance.
