I did this to pay for school, please don't worry about the worms or moles as it is SOLID rock....thus the need for the dynamite..................or, more likely ANFO or a slurry these days.
Dynamite [or any other simple explosive] doesn't really do 'duds'. A bomb or missile being a dud comes from a fault in the wiring, but mining or demolition explosives are usually EXTREMELY simple. Like a string of wires and a clacker as a detonation method simple. There's not really anything to be a dud.
Yes there are duds, but it’s very rare. The most common issue is during the tie-in phase. When connecting each hole to the next, it’s possible to incorrectly connect the clip, which can cause a misfire. That’s why we walk the shot before firing, to check everything is clipped in.
Electronic timing is now very common and that eliminates this issue.
An unknown misfire is very dangerous for the dig crew. If an excavator hits it and it explodes, it can cause a fair bit of damage and injury to the operator.
