Summary
A job that involves using drills or hammer drills to bore holes in rocks at quarries, preparing for blasting or splitting and crushing.
Description
Rock drillers (quarries) operate crawler-type or pneumatic rock drills to bore holes into bedrock. After drilling, they load explosives, set blast holes, and safely and efficiently split and crush rocks. Sites involve a lot of dust and noise, so they wear dust masks and protective gear while thoroughly managing safety. They collaborate in teams to perform tasks and also handle machine maintenance and inspections.
