Blast wave propagation in a granite rock mass and its interaction with existing discontinuities are simulated and studied by means
of UDEC software. For this purpose, a blast shock wave is simplified as a triangular pulse, with the specific maximum pressure
of 16.5 GPa and time duration of 0.01 to 0.08msec, which was placed in a 200 mm diameter blasthole. Results of the numerical analysis along the discontinuity are compared with both field results and the Dowding empirical formulae. A relatively good
correlation is observed between numerical analysis results and field data.
