>> Products Description

The 300m truck-mounted reverse circulation (RC) drilling rig is a high-performance exploration rig designed to deliver efficient, dry sample recovery in deep mineral and geological drilling projects. Equipped with a reverse circulation system, this rig provides uncontaminated, representative samples ideal for mining exploration and resource estimation.

Built on a heavy-duty 6x6 or 6x4 off-road truck chassis, the rig ensures exceptional mobility across rugged terrains. It is powered by a high-torque diesel engine and features an integrated high-pressure air compressor, cyclone sample separator, and a robust hydraulic system. The RC drilling method used enables continuous, high-speed drilling with minimal sample contamination.

This rig is engineered for performance in remote and challenging environments, offering depth capabilities of up to 300 meters while maintaining rapid drilling speed and sample integrity. The modular design also allows for ease of maintenance and transportation.

>> Features

True Reverse Circulation Sampling
Delivers dry, uncontaminated samples using dual-walled drill rods.

Air is injected between the inner and outer rods to lift cuttings directly from the bit to the cyclone.

High Drilling Depth Capacity
Capable of reaching up to 300 meters (984 feet) in RC drilling mode.

Ideal for mid- to deep-level mineral prospecting and borehole programs.

Heavy-Duty Mobile Chassis
Mounted on a 6x6 or 6x4 truck with off-road capability.

Enables fast site-to-site relocation without crane or trailer.

Powerful Integrated Air System
Includes onboard high-pressure screw air compressor (e.g., 25 bar, 24 m³/min).

Ensures continuous airflow for cuttings lift and hole cleaning.

Advanced Hydraulic Controls
Fully hydraulic operation with joystick-based control system.

Precise control over feeding, rotation, and lifting speed improves safety and drilling efficiency.

Cyclone and Sample Collection System
Built-in cyclone sample splitter collects representative samples for geological analysis.

Reduces environmental impact by minimizing sample loss or dispersion.

Easy Maintenance & Modular Design
Modular component layout for simplified repair and parts replacement.

Designed for minimal downtime in remote field operations.

>> Application

Mineral Exploration: Ideal for RC drilling programs in gold, copper, iron ore, and rare earth mining.

Resource Estimation: Delivers accurate, uncontaminated chip samples for laboratory analysis.

Geotechnical Investigation: Used in slope stability studies and subsurface mapping.

Water Well Drilling: Can also be adapted for deep well drilling in hard rock areas.

Environmental Monitoring: Suitable for installing monitoring wells and collecting soil samples.

>> FAQ

Q1: What is reverse circulation (RC) drilling?
A1: Reverse circulation drilling uses dual-walled drill pipes to allow compressed air to circulate down the outer tube and lift cuttings up the inner tube. It produces clean, dry, and uncontaminated rock chip samples ideal for geological analysis.

Q2: What kind of truck chassis is used?
A2: The rig is typically mounted on a heavy-duty 6x6 or 6x4 off-road truck such as a Foton, Sinotruk, or Dongfeng chassis, which provides excellent mobility even in harsh terrain conditions.

Q3: What is the maximum drilling depth of this rig?
A3: This RC rig can drill up to 300 meters (984 feet) in reverse circulation mode, depending on formation hardness and air supply.

Q4: What size drill rods and bits are used?
A4: The rig is compatible with 3.5" to 4.5" OD dual-wall RC rods and RC hammer bits, with options to customize based on project requirements.

Q5: Can this rig be used in remote or high-altitude locations?
A5: Yes, its robust powertrain, integrated air system, and truck-mounted mobility make it highly suitable for remote, mountainous, or desert environments.

Q6: Is after-sales support and training available?
A6: Yes. We provide on-site training, technical support, spare parts supply, and remote troubleshooting to ensure your rig runs efficiently throughout its lifetime.
