GL‑300Q Underground Core Drill Rig 45Kw Electric Diamond Core Drilling Rig For Tunnel Mining

The GL-300Q Underground Core Drill Rig is a full-hydraulic, split-type coring machine engineered for underground mine and tunnel geological exploration. Driven by a 45kW electric motor, it delivers a spindle speed of 0–1000 r/min and 660Nm of torque. The rig supports ±90° dip angle and 0°–360° azimuth angle drilling, and is compatible with AQ/BQ/NQ wireline coring tools. Its modular separated structure allows easy transport and assembly in narrow underground workings, making it well suited to ore sampling and rock core drilling projects.

• Wide Spindle Speed Range: Adjustable 0–1000 r/min spindle speed adapts to diverse rock formations for stable coring operation.
• Powerful Spindle Torque: 660Nm spindle torque ensures strong cutting capacity for hard rock underground mining projects.
• Flexible Drilling Angle: Supports ±90° dip angle and 0°–360° azimuth angle, meeting downward, horizontal and upward borehole drilling demands.
• Reliable Hydraulic System: 20MPa rated hydraulic working pressure provides steady thrust and tension for drilling work.
• Large Axial Thrust & Tension: 65kN axial thrust and 65kN axial tension guarantee smooth feed and retraction of drill rods.
• Wireline Coring Support: Compatible with BQ/NQ/AQ drill tools for efficient wireline coring in horizontal and downward boreholes.
• Split-Type Modular Structure: Separated main machine and power carriage design simplifies transportation and installation in narrow underground tunnels.
• Stable 45kW Electric Motor: Sufficient power output for long-time continuous underground drilling.
• Complete Drilling Capacity: Reaches a maximum 500m downward drilling depth, satisfying geological exploration and ore sampling requirements.
• Independent Operation Console: Stand-alone control panel with clear gauges enables convenient, intuitive on-site operation.

Actual drilling depth depends on rock conditions and the selected drill tools.
