  Effect of Free Surface on Ground Vibration and Burden for Blasting Excavation

  Abstract: Urban rock excavation requires low vibration and rapid excavation. The existing free surface of the blasting excavation affects the level of vibration and the excavation efficiency. In this study, an in-situ experimental test was performed to verify the free surface effects. A continuous free surface was generated with different burden using abrasive waterjet cutting technology. The blasting...
