摘要
通过一个 5× 10 4m3 的场平石方爆破工程实例 ,提出了平孔药壶坍塌爆破设计思路 ,介绍了扩壶、装药等施工工艺及爆破效果 ,达到了爆破安全、爆渣块度小、施工速度快。
The design of horizontal hole springing and rock breaking out blasting are applied to the 50, 000 m 3 ground leveled rock blasting engineering. Hole springing, hole loading and blasting effect are introduced. The safety blasting, little blasting fragmentations, reduced working time and lowered blasting costs are the main achievements in the engineering.
