Day-to-Day Responsibilities
Design blast patterns for each bench or face, setting hole diameter, depth, burden, spacing and charge weight.
Select explosives, initiation systems and delay timing to suit the rock type and the aim of the blast.
Check drill-hole layouts and supervise charging, stemming and firing with the shot-firing team.
Monitor ground vibration, airblast and flyrock, and adjust designs to stay within prescribed limits.
Enforce safety rules, including exclusion zones, warning signals, misfire handling and secure storage of explosives.
Review each blast's results, such as fragmentation, muck pile shape and wall damage, and update the design for the next round.
Maintain blast records and report to the mine manager and statutory officials as required.
