The ST 350 core drilling rig is widely used in:
- Geological survey and geophysical exploration
- Road and bridge construction survey
- Structural quality inspection of geotechnical blasting holes
- Grouting holes and concrete works
- Agricultural water well drilling construction
Operating a core drilling rig requires significant experience and skill. During construction, operators must rely on feedback from the equipment to judge conditions within the hole. The two most critical methods for operation are:
- Listening to the sound of the equipment
- Monitoring the drilling rate
- Check oil level, coolant, and hydraulic oil levels
- Inspect all connecting screws for proper tightness
- Add oil mist as needed (avoid using contaminated oil)
- Verify consistent operation of left and right chains
