    Work Activities

    • Examine blast areas to determine amounts and kinds of explosive charges needed and to ensure that safety laws are observed.
    • Tie specified lengths of delaying fuses into patterns in order to time sequences of explosions.
    • Place safety cones around blast areas to alert other workers of danger zones, and signal workers as necessary to ensure that they clear blast sites prior to explosions.
    • Place explosive charges in holes or other spots; then detonate explosives to demolish structures or to loosen, remove, or displace earth, rock, or other materials.
    • Insert, pack, and pour explosives, such as dynamite, ammonium nitrate, black powder, or slurries into blast holes; then shovel drill cuttings, admit water into boreholes, and tamp material to compact charges.
    • Mark patterns, locations, and depths of charge holes for drilling, and issue drilling instructions.
    • Compile and keep gun and explosives records in compliance with local and federal laws.
    • Measure depths of drilled blast holes, using weighted tape measures.
    • Connect electrical wire to primers, and cover charges or fill blast holes with clay, drill chips, sand, or other material.
    • Lay primacord between rows of charged blast holes, and tie cord into main lines to form blast patterns.
