ISKRA-T Electronic initiating system
ISKRA-T is an electronic delay initiation system based on shock tube and blasting cap. ISKRA-T combines the accuracy of electronic firing systems and convenience and ease of assembly of non-electric firing systems with shock tube. It is used for surface blasting and basting operations in gas and dust safe underground mines and pits.
Advantages of ISKRA-T systems:
– reduced seismic impact of blasting operations on adjacent infrastructure
– the opportunity of reducing explosives consumption 10-15 % under same drilling and blasting conditions
– delay timing precision
– easy and quick assembly of blasting circuit, same as when applying SINV systems;
– no additional training for blasters
– the opportunity to design blasting by setting any constant delay series between holes and separate delay series between lines, as well as staggered delay series.
