ZYL-15000D – Long-Reach In-Seam Directional Drilling Rig for 1500m Methane Drainage
The ZYL-15000D is a high-efficiency in-seam directional drilling rig engineered for large-scale 1500m methane drainage in gassy, outburst-prone longwall mines. Delivering 15,000 N·m of continuous torque, it reliably constructs 1,500-meter boreholes entirely within the coal seam—even in fractured or soft strata—maximizing gas capture while minimizing energy loss and hole collapse risk.
Developed in collaboration with leading Chinese coal safety research institutes—including the China Coal Research Institute (CCRI)—and field-proven in over 200 deployments across Shanxi, Inner Mongolia, and international high-gas basins, this modular directional drilling rig excels at creating tree-like (multi-branch) borehole patterns, a technique proven to increase methane extraction by up to 35%. Its modular design enables rapid switching between straight and branched drilling modes in under 30 minutes, while the low-profile crawler-mounted chassis navigates roadways as narrow as 3.5 meters.
Real-time data from integrated MWD (Measurement While Drilling) tools provides continuous monitoring of azimuth, inclination, and tool face, enabling precise steering around geological hazards and reducing deviation-related rework by up to 40%.
Manufactured by a subsidiary of Shanxi Jinneng Holding Group—a Fortune Global 500 enterprise with deep roots in China’s energy sector—the ZYL-15000D complies with GB 3836 explosion-proof standards and carries the mandatory China Coal Mine Safety Mark (MA). It offers a cost-effective, field-proven alternative to Western rigs without compromising depth capability, reliability, or safety.
For mines seeking scalable, MA-certified in-seam drilling performance at 1500m range, the ZYL-15000D delivers unmatched value through modularity, proven deployment experience, and enterprise-grade support.
