Vibration Energy Comparison Helps Identify Formation Time of New Free Surface in Urban Tunnel Blasting
Cut blasting creates new free surfaces that facilitate rock breaking and reduces blast vibration. However, the time when the new free surface is formed is not clear in on-site blasting practices. This paper proposes a method to identify this formation time through a vibration energy comparison. Firs...
