Experimental study on mesoscopic damage and fragmentation characteristics of hard rock under repeated particle impacts

Particle impact, a new drilling technology, has been applied in drilling and gas and oil exploitation. Also, it is considerably promising as an assisting rock-breaking method for the excavation of tunnels in extremely hard rocks. In this paper, an experimental study was conducted to investigate the...
