Overview
A reverse circulation drilling rig designed for mineral exploration, geotechnical surveys and deep-hole drilling. The YG150RC combines reverse circulation sampling with a crawler-mounted chassis for site mobility and stable operation in varied ground conditions.

Key Uses

• Mineral and ore exploration
• Deep hole drilling (up to nominal 150 m)
• Soil and rock sampling with high sample integrity
• Large-scale construction site investigations (roads, bridges, foundations)
• Groundwater and deep well drilling
• Geotechnical and environmental monitoring

Working principle and core functions
The rig uses reverse circulation (RC) technology: high-pressure air carries cuttings upward through the inner drill pipe, preventing annular contamination and delivering cleaner, less mixed samples. The system supports efficient sample recovery and consistent drilling quality for exploration tasks.

Technical strengths

• High sample purity: Reverse flow reduces contamination from annular cuttings.
• Fast penetration rate: Effective in hard rock and deep layers.
• Simple on-site maintenance: Accessible components for routine service.
• Stable performance: Compatible with standard air compressors and support systems.
• High adaptability: Can integrate with RC drilling rigs and reverse circulation drilling systems for enhanced performance in harsh conditions.
