ZYL-7500D – In-Seam Directional Drilling Rig for 500m Applications in Low-Headroom Roadways (<3m)

The ZYL-7500D is a compact yet fully capable in-seam directional drilling rig engineered for 500m methane monitoring, grouting, and shallow drainage in confined underground environments. With a total height of just 1,550 mm and operating weight under 7 metric tons, it accesses low-headroom roadways (<3 meters clearance) where larger rigs cannot operate—making it ideal for thin-seam mines, secondary development headings, and rehabilitation zones across China’s Yunnan and Sichuan basins.

Despite its compact footprint, the ZYL-7500D delivers 7,500 N·m of continuous torque and achieves reliable borehole depths up to 500 meters entirely within the coal seam. Its lightweight frame uses high-strength steel alloys, while the simplified hydraulic circuit reduces maintenance points by 30% compared to conventional designs. The intuitive control layout enhances operator comfort during extended shifts in tight spaces.

As part of Shanxi Jinneng Holding Group’s (Fortune Global 500) accessible technology initiative, the ZYL-7500D undergoes the same 72-hour full-load testing and MA certification process as the flagship ZYL-18000D. Each unit complies with GB 3836 explosion-proof standards and carries the mandatory China Coal Mine Safety Mark (MA).

Backed by a 2-year global warranty and spare parts availability, the ZYL-7500D offers small-scale mining teams a trusted, cost-effective entry into precision directional drilling—completing our portfolio from 500m (ZYL-7500D) to 1500m (ZYL-15000D/ZYL-18000D).
