What will I learn?
This course equips participants with hands-on abilities to design and carry out secure, productive bench blasts employing bulk ANFO. Key topics include explosive characteristics, charge calculations, burden and spacing guidelines, choosing hole sizes and depths, plus non-electric timing sequences. Learners will excel in managing vibration, airblast, and flyrock risks, integrating rock mass analysis for superior fragmentation, and adhering to structured protocols for blast planning, team coordination, emergency handling, and meeting regulatory standards in Liberian operations.
