Large Diameter Core Drilling
Large diameter drilling is used for applications requiring increased borehole size, volume, and stability beyond conventional drilling methods. These programs support a range of mining and infrastructure requirements where larger openings are needed for material access, fluid movement, or installation capacity.
Depending on project objectives and ground conditions, large diameter holes can be completed using rotary or flooded reverse drilling systems. Successful execution requires appropriate equipment selection, effective circulation management, and experienced operators capable of maintaining borehole integrity through challenging formations.
Our large diameter drilling capabilities include:
- Bulk sampling programs
- Ventilation and dewatering holes
- Infrastructure and service installations
- Pre-collar drilling for deep exploration programs
- Geotechnical and environmental investigation holes
Large diameter drilling requires specialized equipment, careful planning, and disciplined execution. Our teams combine robust drilling systems with experienced field personnel to deliver reliable boreholes that meet project requirements while maintaining safe and efficient operations.
