Pre-Split Drilling
Our pre-split drilling service creates a fracture plane between the final wall and the production blast, ensuring smooth blast results and stable pit walls. Using advanced GPS-guided equipment, we deliver millimeter-accurate hole placement for optimal fragmentation control.
Key Benefits
Improved wall stability and reduced overbreak
Better fragmentation control for easier material handling
Enhanced safety through controlled blast effects
Reduced blast vibration impact on nearby structures
Cost savings through optimized explosive usage
Applications
Open pit mining final wall creation
Quarry bench stabilization
Civil construction rock excavation
Slope angle optimization
