Field Applications and Quantification of Electronic Detonator Technology (f6aba4f2-0ecc-4a09-a9b0-132d9c5ded54)

Recent studies and limited tests indicate favorable results utilizing high accuracy electronic detonator technology over conventional non-electric pyrotechnic systems. This study discusses the application of this technology using the Daveytronic programmable system in an on-going production basis. The study quantifies the performance as it relates to fragmentation, excavation, vibration and productivity in an eastern U.S. aggregate mining operation. In order to insure accurate data, tight field controls were adhered to during the drilling and blasting process as they related to blast design, bench preparation, pattern layout, drilling and blasthole loading. Following the blast the excavation and crushing procedures were studied to quantify any down stream advantages due to improvements in fragmentation. This study will help provide the industry with information as to the advantages of high accuracy electronic blasting systems over conventional pyrotechnic systems and show the results of an operation utilizing electronic detonator technology through their production season.
