In-Seam Directional Drilling Rigs for Coal Mines

Engineered by a Fortune Global 500 Leader in Mining Technology

As a Fortune Global 500 enterprise, Shanxi Jinneng Holding Group delivers world-class in-seam directional drilling rigs trusted by mines across Asia, Africa, and Latin America. Unlike general underground drills that penetrate rock layers, our systems are exclusively engineered to drill long-range boreholes entirely within the coal seam—the scientifically proven method for maximizing methane extraction, preventing rock bursts, and ensuring longwall safety.

Why In-Seam Drilling Outperforms Cross-Measure Methods

Our in-seam directional drilling rigs operate 100% within the target seam, delivering critical advantages:

• 30–50% higher gas flow rates due to uninterrupted seam exposure
• Lower torque resistance (no hard rock) = longer tool life & reduced energy consumption
• Precise trajectory control via integrated MWD (Measurement While Drilling), maintaining ≤1% deviation over 1,500 meters
• Reduced hole collapse risk in soft, gassy coal seams

Validated by operational data from over 200 high-gas mines in China, our in-seam approach has contributed to an 85% reduction in outburst incidents.

Performance-Tiered In-Seam Rigs for Every Mine Condition

Ultra-High-Torque In-Seam Rigs (15,000–18,000 N·m)

For 1,500+ meter in-seam methane drainage in deep, high-stress coal seams.

→ ZYL-18000D: A high-performance in-seam directional drilling rig with modular transport design, ideal for national-level gas governance projects and complex tree-like borehole networks.

Standard Long-Hole In-Seam Rigs (6,000–9,000 N·m)

Optimized for rock burst prevention and rapid deployment in auxiliary tunnels.

→ ZYL-9000D: Proven in-seam directional drilling rig for soft coal conditions, achieving 1,000m depth with 9,000 N·m torque

→ ZYL-8000D: Integrated pump truck configuration for self-sufficient operation in remote headings

Compact Dual-Mode In-Seam Rigs (<7,500 N·m)

Built for narrow roadways (<3 m height), geological surveying, and pilot-scale drainage programs.

→ ZYL-6000D: Self-propelled in-seam rig with intelligent torque switching (4,000 N·m economy / 6,000 N·m high-power mode) and 1-meter continuous stroke—reducing rod connections by up to 30%.
