Product Description: The YGRC-350 is a reverse-circulation exploration drill rig designed for sampling rock cuttings from hard rock formations in deep-hole exploration. With a maximum drilling depth of 350 meters, it utilizes an air-lift reverse-circulation drilling technique, offering high drilling efficiency and excellent borehole quality.
Product Features: 1) Deep-hole capability: Maximum drilling depth of 350 m 2) Hard-rock suitability: Suitable for rock with a hardness (f-value) of 6–20 3) Hole diameter range: 105–400 mm; supports continuous core sampling for small-diameter holes 4) Drill string configuration: Drill rods available in diameters of Φ89, Φ102, and Φ114 mm, with lengths of 1.5 m, 2 m, or 3 m 5) Operational efficiency: 3.3 m single-pass feed stroke, reducing the frequency of rod coupling and uncoupling 6) Chassis and support: Hydraulic crawler-mounted chassis (industrial-grade steel tracks); travel speed of 2.5 km/h; gradeability of 25°; equipped with four high-reach hydraulic outriggers
Application Scenarios: Used for grade-control sampling in mineral exploration, geological reconnaissance via medium-to-deep boreholes, hydrogeological and water-well investigations, engineering geological surveys (for highways, railways, bridges, tunnels, and dams), placer/alluvial gold exploration, and the assessment of mined-out areas and tailings. It is well-suited for operations in mountainous or hilly terrain, as well as in remote mining areas with limited accessibility.
