摘　　要：介绍了在某市区内进行的大孔径浅孔爆破实践,实践表明:大孔径浅孔控制爆破是快速、高效完成复杂环境坚硬岩石爆破的有效方法;控制个别飞石的主要途径是根据炮孔深度和炮孔直径,选择合理的炮孔装药系数和必要的防护措施。这种爆破法可为今后相同类型的岩石爆破提供借鉴和参考。This passage introduces the practice of large-aperture and short-hole blasting in one city.Practice demonstrates that large-aperture and short-hole blasting is the effective way to quickly blast hard rocks in complicated situation.The effective way to control individual slung shot is to choose right index of powder charging and necessary safeguard measures based on hole depth and diameter.This method can provide reference for the same type of rock blasting in the future.
