rock crushing mechanism

Chipping and crushing mechanisms in orthogonal

2016-12-1  The rock removal mechanism in the rock cutting process includes crushing and chipping failure modes. Crushed and powdery chips are attributed to the crushing mode while chunk-like chips are formed due to the chipping mode. Chipping of rock has been concluded to be caused by either tensile or shear stresses by different researchers.

On the rock-breaking mechanism of plasma channel

2020-11-1  The basic mechanism of rock breaking in plasma channel drilling is initial plasma channel crack formation under high-voltage pulse; then the plasma channel expands rapidly and some initial shear cracks are formed around the plasma channel; after that several tensile damage cracks form around the initial shear cracks; and when the cracks penetrate to the free surface, the internal energy inside the rock
