In deep underground mining, the damage evolution and vibration response mechanisms of
rock caused by cut blasting are different from those of shallow rock. It is essential to
understand the mechanisms for underground engineering safety. In this study, field raise
blasting with vertically parallel and dense bunch longholes was designed and performed at
the Shaxi underground mine in China. The raise contour and the blasting vibration were
measured in the field, and regression analyses of the peak particle acceleration (PPA) were …
