Influence of Initiation Modes in the Bundle-Series Initiation of a Large Number of Shock Tubes by Detonators

The bundle-series initiation is currently used as the method for simultaneously transmitting blast signals from a detonator to large number of shock tubes blasting using and its modes affect ability probability signal transmission. A numerical study influence on pressure impulse generated by detonators transmitted has been undertaken with ANSYS AUTODYN code validated through experimental results transmission tubes. Numerical simulations experiments lateral frontal For bundle many tubes, peak pressures impulses affected within all beside first layer around detonator, probabilities were higher mode than mode. magnitude numerically obtained shows good correlation experimentally Finally, are employed in application simultaneous initiating blastings mining construction.
