vibrations according to the standards. In open pit mines, ground vibration caused by repeated blasting can stimulate loose rock blocks in the nearby pit walls, leading eventually to their failure. Repetitive blasts during the mine life may cause a reduction in the shear strength and bearing capacity of the major discontinuities in the mine site.
