Mining Exploration Drilling Rig Selection Guide
Choosing the right mining exploration drilling rig is critical for geology teams and mining contractors. The rig you select directly impacts core recovery rates, drilling speed, and the quality of geological data. Browse our mining & exploration rig range.
1. Core Drilling vs. RC Drilling
Diamond core drilling produces solid cylindrical core samples for resource definition. Reverse Circulation (RC) drilling brings cuttings to the surface faster for initial exploration. Many programs use RC for rapid drilling followed by diamond core for detailed definition.
2. Rod Size and Depth Capacity
| Rod Size | Core Diameter | Typical Depth | Best For |
|---|---|---|---|
| BQ | ~60 mm | up to 500 m | Shallow reconnaissance |
| NQ | ~47.6 mm | up to 1000 m | Most common exploration standard |
| HQ | ~63.5 mm | up to 1500 m | Detailed resource definition |
| PQ | ~85 mm | up to 1200 m | Large core for metallurgy |
3. Rig Portability and Site Access
Exploration sites are often in remote, rugged terrain. Tracked rigs handle uneven ground best. Skid-mounted portable rigs can be broken down for helicopter transport. Truck-mounted rigs work for accessible areas.
4. Hydraulic System Specifications
Compare pullback force (higher = handles deeper holes), feed stroke length (longer = fewer rod changes), rotary speed and torque, and air compressor capacity for RC/DTH work.
