| 摘 要： | 随着中深孔爆破、光面爆破的广泛应用和岩巷快速掘进生产要求,反向爆破在生产过程中体现出了一定的优越性;主要探讨反向爆破的特点,通过对比正向爆破的装药结构、爆破冲击波作用效果、爆炸应力场对岩石的作用等方面;通过理论分析和实际生产中的应用,得出反向爆破无论是在爆破效果、掘进速度、爆破安全性等方面都有不同程度的提高,因此,在制定安全措施的前提下,采用毫秒延期、反向爆破,要优于正向爆破。

| Abstract: | Along with the widespread application of the center deep hole demolition,the prefacing demolition and the need of lane high-speed driving production,the reverse demolition has manifested the certain superiority in the production process.This article mainly discusses the characteristic of reverse demolition through contrast demolition powder charge structure,demolition impact wave action effect,the aspect of detonation stress field and so on.The reverse demolition has the merit in the mine shaft crag lane high-speed driving which the forward demolition is unable to compare.Through the theoretical analysis and actual production application,the reverse demolition has got great enhancement in some aspects,such as,blasting effect,tunneling speed,demolition security.Therefore,using the reverse demolition which has millisecond extension must surpass the forward demolition under the condition of safe measures. |
