Development Drill Rig for Mining High-Efficiency Hydraulic Single-Boom Drill Suitable for Underground Operations

Product Description

 Product Description                     

Features
This high-performance single-boom face drilling rig is engineered for underground excavation projects in mining, water diversion, railway, and defense applications, adapting to drift cross-sections from 4m ×4 m to 7×6.7 m. Featuring full-hydraulic drive, precise positioning, and wide coverage, it is an ideal solution for complex underground drifting scenarios.

Equipped with a fully hydraulic parallel telescopic boom and dual-triangle stabilization structure, the rig enables full-face drilling in a single positioning, significantly improving construction efficiency. It comes standard with an 18 kW rock drifter (with 20 kW/22 kW high-power options), delivering a penetration rate of 0.8-2.5 m/min even in F17 hard rock. The dual-damping design extends tool lifespan and reduces maintenance costs.

To handle harsh underground conditions, it integrates automatic anti-jamming, rod retraction, and collision protection functions, paired with an intelligent monitoring system for real-time equipment status tracking. Both onboard and remote operation modes are supported for flexible adaptation to varying underground environments. The diesel-powered four-wheel drive articulated chassis offers 14° climbing capability and a travel speed of 13.5 km/h, ensuring excellent mobility in narrow drifts. A FOPS (Falling Object Protective Structure) and ROPS (Roll Over Protective Structure) certified canopy provides robust operator safety.
