- Abstract
A brief review on the origin of V-notched blasting and its application in engineering is given. A study on the fracturing mechanism and stress intensity factor at the tip of V-notch and parameter of the V-notched rock blasting is introduced based on reference given in this paper. It represents an idea of spiral V-notched blasting at last.
