There are several types of drill rigs, each designed for specific applications in construction, mining, geotechnical, and civil works.
Common types of drill rigs:
- Rotary Drill Rigs: Use a rotating drill bit to bore through soil or rock; widely used for piling, water bores, and mineral exploration.
- Percussion/Down-the-Hole (DTH) Rigs: Use hammering action to break hard rock; suitable for quarrying, mining, and deep rock drilling.
- Hydraulic or Pneumatic Rigs: Often used for blasting, civil construction, or rock excavation; operate with hydraulic or compressed air systems.
- Crawler-Mounted Rigs: Mobile rigs on tracks; ideal for uneven or remote terrain.
- Truck-Mounted Rigs: Provide mobility on roads and are suitable for piling, exploration, or water bore drilling in accessible areas.
- Deepwater Offshore Rigs: Large rigs designed for drilling in oceans or deepwater sites, often with sophisticated stabilisation and positioning systems.
- Concrete/Core Drilling Rigs: Compact rigs used for precise cutting or coring in concrete or rock surfaces.
The choice of rig depends on site conditions, drilling depth, material hardness, and project type.
