Abstract: This paper shows the development of a FEM model that predicts ground vibrations due to blasting, a very complex problem involving factors very difficult to quantify: ground anisotropy, sequencing time of the blasting shots, action of each shot, etc. From the vibration records in several blasts in a limestone quarry, we have approximated the referred factors obtaining a model that simulates with enough accuracy the complex waves originated in real blasts. Afterwards, we detail a work methodology which was developed including randomness. This methodology allows the practical use of the models by the engineers who design the blasts.
