笼式钢筋混凝土深井掘深控制爆破实践

Practice of Control Excavation Blasting for Deep Cage Steel Concrete Structure Well

对难以用机械钻孔的高密度笼式钢筋混凝土整体结构且井口较小的深井,采用射孔器射孔和切割器切割钢筋等办法,应用控制爆破法对深井进行掘深爆破,爆破效果良好,其爆破方式为这类笼式钢筋混凝土结构的深井爆破提供了较好的参考作用。

Using perforation and cutting method, the high density deep cage steel concrete structure well with small wellhead which is difficult to use mechanical drilling is deeply dig by control blasting technology. The blasting effect is good and the method provides a good reference for the blasting of cage steel concrete structure well.
