摘　　要：阐述了水平深孔爆破在城区石方开挖中的应用,并初步探讨了水平孔爆破的破岩机理。结合实际工程介绍了该技术应用条件、可行的爆破参数及其选取法、施工工艺等。作为辅助性爆破,水平深孔爆破在城区应用中无需进行飞石防护,大大加快了爆破工程进度,体现了水平孔爆破优越性。The paper elaborated the application of level deep-hole blasting for excavation project in city. Combining the actual engineering, it introduced the applicable condition of the technique, viable the blasting parameter plus its selection in design, and the construction techniques etc. Being as an assistance blasting, the level deep-hole blasting had no the requirement of carrying on flying rock protection in the city zone, and hence, it speeded the construction schedule consumedly,showed the superiority of level deep-hole blasting.
