Abstract. The mining industry is the main blasting process, the quality of performance which depend on all subsequent processes of extraction and processing of minerals.
In recent decades, conducting blasting technology has been rapid development. New technologies in drilling and blasting, and include the introduction of high-performance drilling rigs, and the use of safer emulsion explosives, and the use of new means of priming.
It is noted that the reduction in cost BSB is mainly achieved through the introduction of electronic blasting initiation system that provides reliable synchronization alternately triggered wells.
This technology helps to maximize the use of the control system for the release of explosive energy, and each works well guaranteed in a certain sequence that allows you to avoid the adverse effect of "overlay", ie simultaneous operation of several wells. In addition, significantly reduced the negative influence of seismic and acoustic mass explosions in the environment, reduces the emission of harmful combustion products and dust in the atmosphere. The main result has improved the results of blasting operations, reducing the percentage of oversize and exit screenings, and they thus reduce the cost of excavation, transportation and processing of blasted mass.
Currently in production blasting in the world there are different systems of priming. The article discusses the principle of operation and parameters of one of the most advanced in the world - the electronic charge initiation system I-KON™. It is shown that due to the high accuracy of electronic detonators and a wide range of possible delays, it is possible to choose a blasting scheme that exactly matches the conditions for drilling and blasting. The I-KON™ system under consideration contributes to seismic safety and makes it possible to achieve an optimal distribution of the explosion energy in the array. At the same time, BVR optimization is possible by selecting appropriate schemes for mounting the explosive network. The result is a more efficient crushing of the rock mass, which can help reduce drilling and blasting costs.
Keywords: drilling and blasting, electric blasting, electronic initiation, advanced technologies.
