Drilling-Blasting Operations
Drilling and blasting operations break rock to free ore from the host formation, using patterned boreholes and engineered explosive charges to control fragmentation and throw. Operators must balance powder factor, hole spacing, and timing delays to maximize muck pile diggability while limiting vibration, flyrock, and wall damage. Mastery of this skill is core to productivity in open-pit and underground mining and is tightly regulated under MSHA and ATF rules.
