Applications of Hydraulic Core Drilling Machine
- Mining Exploration: Used for extracting mineral samples with high precision. A core drilling machine for mining ensures detailed geological analysis.
- Geotechnical Investigations: Plays a critical role in assessing soil and rock properties for construction projects.
- Water Well Drilling: Some models can be adapted for water well drilling operations.
- Oil and Gas Exploration: Hydraulic core drills are used for shallow drilling in petroleum and natural gas research.
- Infrastructure Development: Employed in tunnel ventilation, dam grouting, and foundation reinforcement projects.
In addition to hydraulic core drilling, YG Machinery also offers RC Drilling Rigs for mineral exploration. RC rigs utilize reverse circulation technology to bring rock cuttings directly to the surface, providing fast, low-contamination sampling. This complements core drilling by enabling early-stage exploration programs to identify mineralized zones efficiently and cost-effectively.
Finding the Right Core Drill Rig for Sale
Choosing the right core drill rig for sale involves evaluating factors such as drilling depth, terrain conditions, and budget constraints. YG Machinery offers a range of high-performance models that cater to different drilling needs, ensuring maximum efficiency and reliability.
Customer Case: Hydraulic Core Drilling in Namibia
In 2025, a mining company in Namibia purchased a YGX-600 hydraulic core drilling machine for copper exploration in the Otjozondjupa region. The geological terrain was rugged, with hard rock and fractured zones, making conventional rigs inefficient. After using the YG hydraulic core rig for three months, the client reported a 25% improvement in core recovery rates and smoother drilling even in complex formations.
The company also integrated an reverse circulation drilling machine for preliminary sampling, which helped identify promising zones before detailed core drilling, reducing overall project cost and time.
