摘要
采用平孔药壶爆破与竖孔药壶爆破相结合的方法开挖较陡地形山体,充分利用炸塌相结合的作用,达到施工速度快、爆破成本低的工程目的,同时把边坡高度控制在合理的范围内,保证作业安全。对平孔药壶爆破与竖孔药壶爆破在扩壶工艺、装药作业等方面进行了比较,提出了这两种形式药壶爆破的适用条件。
In excavation of steep rock, a method of combining horizontal-hole springing blasting and shearhole springing is used, so as to reach a fastened construction schedule, a reduced blasting costs as well as a safety operation in terms of the control of the slope height in reasonable level. The difference of hole springing, hole loading and applicable condition are given by contrasting horizontal-hole springing blasting with shear-hole springing blasting.
