YG Diamond Core Drilling Rig is compatible with the traditional diamond core drilling rigs and is especially suitable for deep hole geological drilling which requires high coring rate and core integrity. Compared with traditional equipment, it is more stable in operation and the drilling accident rate is significantly reduced, which makes it suitable for highly demanding projects.

Features of Diamond Core Drill Rigs

1. Fully Hydraulic Control System: All operations, including propulsion, rotation, lifting, chuck, and clamping, are centrally controlled by the hydraulic system, eliminating manual errors and enhancing safety.
2. High-Quality Seals and Bearings: Imported seals and thickened main bearings ensure stable performance and extended life in hard rock, fault zones, and complex rock formations.
3. Efficient Drill Bit Combination: Equipped with high-performance diamond drill bits, this drill significantly improves penetration rate, core integrity, and drilling speed.
4. Adaptable to Complex Geological Environments: Maintains vertical and stable drilling in fractured zones, aquifers, and variable rock formations.
5. Easy Operation + Easy Maintenance: Modular design enables rapid routine maintenance and troubleshooting.
6. Export Quality & Global Service: Our products have been exported to markets across Europe, America, Southeast Asia, Africa, and beyond. We offer customized services, global parts supply, and remote technical support.

Typical applications of Diamond Core Drill Rigs

1. Detailed investigation of metal ore resources;
2. Coal mine gas pre-drilling construction;
3. Geothermal well drilling;
4. Geotechnical engineering investigation;
5. Oil and gas exploration auxiliary hole construction;

For customers who need easy mobility and flexible construction, YG also provides hydraulic crawler drill equipped with crawler system, which can be used in mountainous areas, forested areas and other complex terrain.

Diamond Drill Bit Oil Rig

Many customers confuse diamond core drill rigs with diamond drill bit oil rigs, which are used in different applications: the former is designed for geological exploration in mines, while the latter is mostly used in the construction of large-diameter wells on oil rigs, with completely different bit sizes, configurations and torque requirements. The drill bit size, structure and torque requirements are completely different. If the customer is engaged in mineral exploration, it is more appropriate to choose diamond core drill rigs for mining.

Customer Case: Diamond Core Drilling in Tanzania Gold Mine

In 2024, a mining contractor from Tanzania purchased the YGX-600 diamond core drill rig for a gold exploration project near Lake Victoria. The terrain was rocky and unstable, making drilling efficiency a major challenge. After using the YG rig for two months, the customer reported a 30% increase in core recovery rate and smoother operation even in fractured formations.

“YG’s diamond core drill rig runs very steadily and saves us time in every drilling section. Their technical support team was responsive and professional.”
— Mr. Daniel, Project Engineer, Tanzania Mining Co.

The client has since ordered a second unit to expand their drilling capacity in 2025.

Operation Tips and Safety Precautions

1. Before rope coring operation, check the status of wire rope, hook and core barrel to avoid rope breakage and drill jam;
2. Reasonably adjust the propulsion force during the drilling process to prevent abnormal wear or breakage of the drill bit;
3. The hydraulic system shall be checked regularly for oil cleanliness to ensure that the main pump and distribution valve work normally;
4. Clean the mud in the drill pipe in time after operation to prevent solidification and blockage.
