The possibility of use of the Electronic Initiation Systems in Slovene Mining Industry

摘要

Production of technical stone is an important economic branch in Slovenia. In 2009, we had 95dolomite quarries, 27 limestone and 6 silicates quarries, according to the Ministry of EconomicAffairs. Together they produced nearly 15 million tons of aggregates. The production in quarries ismostly performed with drilling and blasting method and only a minor part with other method likemechanical mining method.Usage of electronic initial systems in Slovene mining industry may have many advantages. It enablesan accurate ignition delay and custom programming of the delay. Moreover, the frequency can beinfluenced, which is very important for reduction of negative impacts of mining and for better rockmovement control. Consequently, the result is better material fragmentation, production is increasedand usage of explosives is reduced. The possibility of checking detonators is also practicable withinthis system. The improvement of the parameters described above is possible with computermodelling programs.Programmable Electronic detonators enable to adopt innovative ?Signature-hole blast analysis?technique to simulate, to predict and to control blast inducted ground vibrations, in order to obtainmaximum operational efficiency.In Slovenia, almost all quarries are located near the settlements and villages, therefore it is veryimportant to have maximal control over all factors involved.Our plan for the future is a practical usage of electronic detonators in Slovenia and for that reason wehave done the comparison between classical and new blasting techniques.
