    Abstract
  • In order to study the projectile based rock-breaking method, the impacting principle of a kind of deformed projectile with the type of fan blade was systematic analyzed. On this basis the one dimension theoretical model for the impacting process was formulated. The kinematic variable values of it were calculated and the related structural parameters were discussed. The results show that the velocity relationship between the head and the tail of this deformed projectile is approximately linear, which can be expressed by the Bernolli equation. At the same time, it is beneficial for enlarging the transverse acting range when the inner slope angle is decreased and the number of notch groove is increased.
