抄録

Characteristics of the shell-shaped fracture of rocks by a pure water jet impingement are presented, which is usually observed in a drilling process by non-traversing pure water jets impinging normally onto rock surface in the air. Time dependency of the shell-shaped fracture and its repetition mechanism are clarified by a series of laboratory experiments, as well as the effect of the driving pressure and the consequent fragmentation of rocks, and it will be discussed that the shell-shaped fracture is an important phenomenon which may result in an excellent digging performance applicable to the surface excavation of hard rock and so on.
