Abstract

In this research, the interaction of blast-induced stress wave with the surrounding media is investigated by the UDEC code. The stress wave resulting from the explosion of a cylindrical charge is simulated by a triangular pulse which is the result of an overpressure equivalent to 1860 MPa. This pressure is applied to the blasthole wall as a uniform load. Numerical results are compared with published empirical data for blasting in a granite rock mass. A good agreement between numerical and empirical results was achieved.
