Design of control elements for emulsion explosive energy with programmable initiation

Authors: Overchenko M. N., Mozer S. P., Tolstunov S. A., Belin V. A.

The basic procedures are presented for the emulsion explosive energy control in long boreholes with calculations of efficient delay intervals at different firing times per borehole sections. It is determined that efficiency of a single explosive charge can be enhanced by its decoupling. The decoupling gap has a certain size. The active air gaps in emulsion explosive charges are calculated using the second law of thermodynamics and Pascal’s principle. The tests of the passive air gaps are described. Two most often industrially used cases of different time decoupled charge blasting with programmable initiation are discussed. As a result, it is found that decoupling of the charge and initiation of the charge section using separate intermediate detonators and high-precision electric detonators promotes maintenance of maximum quickness of emulsion explosives. The obtained results can improve efficiency of emulsion explosives in long boreholes, as well as allow a wider range of methods and means for the explosion energy control.

Keywords: safety, blasting, blast physics, air gap, calculation, delay interval, electric detonators, remote blasting.
