GD-600L Fully Hydraulic Core Drilling Rig
The Intelligent Choice for Data-Driven Geoscience
Modern exploration is increasingly a data-driven science.
Geological models are built from assay results, structural
measurements, and geotechnical parameters extracted from core. The
quality of the model depends entirely on the quality of the core
data. The GD-600L Fully Hydraulic Core Drilling Rig is engineered
as the intelligent choice for geoscientists who demand the highest
quality input for their models.
Precision Drilling Performance
The journey of high-quality data begins with controlled,
vibration-free drilling. The GD-600L's three-speed gearbox and
hydraulic plunger motor deliver exceptionally smooth rotation, free
from the chatter and torsional vibrations that can fracture
delicate core. The operator can select the optimal gear for each
formation, ensuring that the core barrel cuts cleanly rather than
grinding or breaking the rock. This precision preserves fine
structures, veinlets, and alteration halos that are critical for
geological interpretation.
Advanced Feed Control System
Feed control is equally refined. The 16-ton hydraulic feed system
provides infinitely variable pressure, allowing the driller to
maintain optimal weight on bit throughout the run. The
ground-contact integrated tower eliminates flex, ensuring that feed
force is applied exactly along the borehole axis. This combination
prevents bit wander, reduces borehole deviation, and ensures that
each core run samples the intended interval without mixing or
contamination.
Angular Flexibility for Targeted Drilling
The GD-600L's angular flexibility—from 0 to 90 degrees—allows
geologists to target structures at their true orientation. Whether
drilling vertical holes for resource modeling, angled holes to
intersect dipping veins, or horizontal holes for geotechnical
characterization, the rig provides the precise alignment needed.
This capability ensures that structural measurements from core are
accurate and that resource estimates are not biased by drill
orientation.
Sample Integrity Preservation
Sample handling from depth to surface is designed to preserve
integrity. The V-shaped self-weight gripper holds the string
securely during rod breaks, preventing any shock that could damage
the freshly cut core. The smooth hoisting action of the auxiliary
winch retrieves the core barrel steadily, avoiding jerks that could
cause the sample to slide or fracture. At surface, the core is
extracted with care, ready for logging, sampling, and analysis.
Comprehensive Data Recording
The rig's instrumentation supports comprehensive data recording.
Standard gauges provide real-time feedback on hydraulic pressure,
engine performance, and drilling parameters. Optional digital
systems can record depth, penetration rate, and other variables,
creating a permanent record that complements the physical core.
This data can be integrated into geological databases, enhancing
the value of every hole.
