Supersonic detonation in rock mass — Analytical solutions and validation of numerical models — Part 1: Stress analysis

Abstract

Abstract This contribution presents studies on supersonic detonations and resulting blast wave propagation in rock. An analytical solution for the supersonic detonation of a cylindrically shaped explosive charge in a blasthole is presented in a form most appropriate for numerical modelling and for the assessment and evaluation of various numerical codes. An application to bench and crater blasting is discussed.
