岩巷反向爆破技术探讨

对正、反向爆破作用机理进行分析和爆破安全性、效果的对比,通过实际生产中的应用,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、中深孔反向爆破,要优于正向爆破。

Rock blasting techmques of reverse

This paper is,reverse blasting mechanism analysis and blasting safety,the effect of contrast,through the actual production,come back,whether in blasting blasting effect,driving speed,blasting safety and so on have different the degree of improvement,therefore,in the formulation under the premise of safety measures,using millisecond extension,in the deep hole blasting reverse,positive is better than blasting.
