摘要
在公路路堑切槽开挖硐室控制大爆破中,采用较大不耦合比较进行松动控制爆破。在较为复杂的地质地形条件下,通过合理地选择爆破方案和设计爆破网路,使爆破取得成功,有效地控制了爆破效果和安全。
Bigger uncoupling is adopted to realize loose controlled blasting in the excavation of chasm notch blasting. Reasonably choosing blasting program and designing blasting network in complicated geological conditions are adopted in the blasting. Therefore the effectiveness and safety of the blasting are controlled effectively.
