At the Lagunas Norte Unit, of the Barrick Misquichilca Mining Company, the plan for the start of 2017 is to expand the dam by the Dafne zone. According to medium-term planning, for the beginning of 2017 comes with the extension of the Tagus by the area of DAFNE. As part of this expansion, blast fronts are closer to two major mine structures;The primary crusher and the Poza. Therefore, in order to minimize the level of vibrations and avoid damage to these two installations, modeling and vibration simulations were performed in order to optimize factors that affect the level of vibrations, including the most important, Delay, time between holes, output sequence, etc. Modeling and blasting simulations with Orica Mining Services' ShotPLus Software was developed with different delay loads. A total of 109 field tests were performed to test the simulation, compiling the results obtained in each ...
