Abstract

Blasting simulation methods are essential for the success of all projects for reaching proposed objectives and minimizing risks. In the following research, it was made a study of case of a blasting made under San Carlos´ Bridge in Antioquia, Colombia, with the purpose of protecting the stapes using detonating cord as a fund delay and Emulind S explosive, analyzing vibration data with O-PITBLAST cell phones and correlating the design to the rock mass. It was used the PPV method or attenuation law and consequently, data obtained by the equipments were simulated. It was possible to conclude that the vibrations taking have the effectiveness for predicting and mitigating risks, not only for the project, but also for nearby buildings. Likewise, it was determined that drilling must be parallel to diaclasas with trained and experimented staff. Also, the detonating cord as fund delay causes a shotgun effect in the basin. Limitations of the following study are based principally in the ignorance of geology and geotechnics in the testing place, and its possibility of including these variables in the development of the project.
