The application of drilling and blasting techniques in the various stages of the operational life of a mine is not only beneficial productively and economically, but is also a source of negative aspects if they are not carried out correctly, such as social, environmental and operational effects. During the detonation process of an explosive there is a release of energy that is not necessarily destined in its entirety to the fragmentation of the material, a percentage of this released energy is transformed into vibrational waves that are transmitted in different directions. In this sense, the present research aims to generate mathematical models for far-field seismic prediction, which allow us to estimate vibration magnitudes as a result of explosive blasting. To do this, he proposes to use Devine's model of the scaled distance, where we will use parameters such as distance (blasting-monitoring point) and operating load (kg of explosive per delay time) that give us ground attenuation laws as a result. As a result of the study, mathematical models for seismic prediction were obtained from elementary waves and complete blasts that allowed us to estimate their level of precision for each of the casescase, during the seismic prediction. Finally, it was determined that seismic prediction equations determined with attenuation laws (k y Alpha) obtained from complete blasts give us prediction results with a better level of confidence, this considering the same study area.
