Abstract

Fluidic shock-drill is a new type of geologic drilling tool. This paper investigates their principles and characteristics. The present author gives an analytical model on their dynamical behaviour based on the theory of Common Mechanics and Fluid Dynamics. Good agreement is obtained between theoretical and experimental results.
