Abstract
The search for safer, more cost effective practices in the mining industry has increased the popularity of non-electric initiation systems in particular shock tube systems. One component of a shock tube initiation system is the trunk line that connects the blast pattern to the firing line and allows the blaster to initiate the blast from a safe distance. It is common practice when blasting to connect the two pieces of shock tube as close as possible in a plastic connecting tube. The purpose of the research was to find the maximum allowable gap distance between the two pieces of shock tube when they are in the plastic connection tube. The experiment was conducted on the three most popular brands of shock tube and the same brand of plastic tubing was used. From the tests it was found that all three products performed similarly with a maximum initiation distance of 6.5 in. to 7.125 in. The results of this experiment revealed that the common practice of putting the trunk line connections as close as possible or even touching is not necessary.
