The JRC300B reverse circulation (RC) drilling rig is a multi-purpose, high-efficiency, and environmentally friendly tracked drilling rig that utilizes advanced gas-lift reverse circulation drilling technology. This rig effectively collects rock dust using a dust collector to minimize environmental pollution and is equipped with a cyclone separator for geological sample analysis. It is ideal for geological exploration, water well drilling, monitoring wells, and ground source heat pump systems.
The JRC300B achieves full hydraulic control, allowing efficient operation of lifting, guide compensation, drill pipe loading and unloading, rotation and feed, legs adjustment, winch control, and walking mechanisms. This significantly reduces labor intensity and enhances both drilling efficiency and construction quality.
Additionally, the rig is equipped with an Automatic Rod Change System and Full Remote Control Operation, making drilling operations more intelligent, efficient, and safe.

Full remote control and automatic rod changing enhance drilling efficiency, safety, and intelligence. Remote control reduces labor intensity and risk, enabling precise operation in tough conditions, while automatic rod changing minimizes downtime and errors for continuous drilling.
Utilizes dual-wall drill rods (outer drill rod + inner tube) to allow drill cuttings to return to the surface through the inner tube, ensuring continuous and steady sampling.
Provides high-quality, contamination-free samples, making it ideal for precise mineral exploration.
Uses large air compressors to dry the rock ahead of the advancing drill bit, enhancing penetration efficiency.
Compared to traditional Down-The-Hole (DTH) and Top Hammer drilling, RC drilling minimizes unwanted material contamination, ensuring more reliable resource calculations.
Powered by a 239kW Cummins Euro-2 diesel engine, ensuring reliable and strong performance.
Capable of drilling up to 300 meters deep, with a maximum hole diameter of 450mm.
Equipped with a high-torque Eaton motor, delivering 11,800Nm of rotation torque for powerful drilling in various geological conditions.
Features a fully hydraulic control system, reducing mechanical wear and ensuring smooth operation.
Uses an electro-hydraulic pilot load-sensitive directional valve for precise control and efficiency.
Includes emergency stop buttons, fire extinguishers, and safety alert systems for enhanced operational safety.
