Hydraulic Deep Hole Coring Machine Mining Deep Drill Hydraulic Rig

The Precision Instrument for Constrained & Sensitive Environments

There is a growing category of drilling projects where physical space, environmental sensitivity, or social license are the dominant constraints—not depth or rock hardness. Working inside existing mine tunnels, on narrow urban lots, within protected ecological zones, or on steep, unstable slopes demands a drill rig that is as much a precision instrument as it is a piece of earth-moving equipment. The GD-300C is engineered for this exacting niche, offering the pinpoint accuracy, minimal footprint, and configurable operation required to conduct high-quality drilling in the world's most constrained and sensitive environments.

Succeeding in constrained spaces requires a fundamental rethinking of size and configuration. The GD-300C’s modular design allows it to be disassembled and brought into locations like underground mine drifts, narrow valley floors, or confined basements where no other drill rig could fit. Its components can be arranged in non-standard layouts to accommodate irregular working areas. This spatial adaptability ensures that the precise geological target—a specific vein in a tunnel wall, a suspect area under a building, a spring source on a cliff face—can be sampled directly, without compromise or estimation from a more convenient but geologically inferior location.

Operating in sensitive environments necessitates impeccable control and minimal impact. The rig’s full hydraulic system provides exceptionally smooth and precise control over feed pressure and rotation, allowing an operator to drill with a level of finesse that prevents unnecessary wallow, overbreak, or sample disturbance. The availability of an electric power source is transformative for indoor sites, archaeological digs, or ecologically protected areas, enabling completely silent, fume-free operation that leaves no atmospheric or noise pollution footprint. This clean, precise performance is essential for maintaining operational permits, community relations, and the integrity of the surrounding environment.

Despite its focus on constrained spaces, it delivers uncompromised data quality. It utilizes standard, industry-accepted wireline coring equipment (BTW/NTW/HTW), ensuring that the cores it produces are directly comparable to those from larger rigs and are perfectly suitable for all standard laboratory assays and analyses. The 90KN hydraulic pull and 300-meter depth capacity provide ample power and reach for the vast majority of targeted, precision-drilling applications, from validating ore grades in a mine wall to sampling soil stability at a proposed bridge abutment on a tight slope.

The GD-300C is the specialist's choice for precision drilling. It masters the challenges of space and sensitivity through modular flexibility, impeccable hydraulic control, and clean power options, delivering laboratory-grade core samples from locations where traditional drilling is impossible, impractical, or simply too disruptive.
