The electronic blast because of its greater precision, nowadays practically covers the whole of the Great Mining. Electronic detonators have several protections against external effects such as dynamic pressure. They allow to qualify as the detonator with the highest dynamic pressure resistance in the market. However, if conditions exceed established resistance values there is always a possibility of failure. The rate of dynamic pressure events at the level of Latin America in the years 2014 - 2015 to date is 1.7 ppm. As a result of the finding of an armed premium with its electronic and nonelectric detonators, associated to the drill No. BF 43 of the mesh P12 4040 174, on July 28, 2016 in the Dafne area began the execution of a series of corrective and preventive measures derived from the investigation carried out by the finding of a booster not started in the material flown, which cont...
