Shotfirer

nounStandard termMining

A certified worker responsible for loading explosives into drill holes and initiating the blast.

A highly trained and legally certified miner tasked with handling all explosive materials on a blast site. They inspect the drilled pattern, load the holes with the correct sequence of primers and bulk explosives, wire the detonators, and clear the area. Once the blast zone is secured, the shotfirer connects the firing line and physically triggers the detonation.

Heard on the job

The drillers just finished the pattern, so the shotfirer is heading in with the powder truck to load the holes.

Insider tip

In many jurisdictions, only a licensed shotfirer holds the key to the blast box, ensuring absolute control over when a shot is fired.
