Blast Design
Burden, spacing, bench height, hole diameter, sub-drilling, stemming, delay timing, powder factor, and charge distribution.
Package 5
Drilling and Blasting Engineering Training
Practical training for quarry and open-pit operations covering drilling productivity, explosive selection, blast design, fragmentation, safety controls, reporting, and blast cost optimization.
Training Focus
Designed for Practical Mine and Quarry Work
This package helps learners connect blast theory with the documents, calculations, safety checks, and field decisions used on site.
Safety and Control
Blast exclusion zones, misfire management, magazine safety, flyrock prevention, vibration control, and blast reporting discipline.
Performance Review
Fragmentation analysis, toe control, back break review, oversize reduction, blast auditing, and cost-per-blast improvement.
