Intelligent Underground Jumbo Drill Delivered to Chile Copper Mine Expansion Project

Advanced Twin-Boom Development Drill Rig Improves Productivity in Chile’s Underground Copper Mining Sector

Intelligent Twin-Boom Jumbo Drill Supports Chile Copper Mine Expansion

CHILE, April 2026

Our company has successfully delivered an intelligent twin-boom underground development drill rig to a large underground copper mine expansion project in Chile. The machine is currently being used for transportation drift excavation, ventilation tunnel development, and production-level access construction.

The project represents another successful application of our underground mining equipment in South America’s rapidly growing underground copper mining industry.

Chile’s Transition Toward Underground Copper Mining

Chile remains the world’s largest copper producer, with many mature open-pit mines gradually transitioning to underground operations as ore bodies extend deeper below the surface.

To support long-term production targets, mining companies are investing heavily in underground infrastructure development, creating strong demand for modern underground jumbo drills capable of delivering higher productivity and operational consistency.

The customer required an advanced drilling solution capable of supporting a large-scale mine expansion project while reducing operating costs and improving tunnel development quality.

Mine Expansion Project

Intelligent Jumbo Drill Designed for Modern Underground Mining

The supplied twin-boom development drill rig incorporates a range of intelligent drilling technologies, including:

· Automatic boom positioning system

· Computerized drilling control

· Real-time drilling monitoring

· Digital drilling data recording

· High-power hydraulic rock drills

· Heavy-duty underground mining carrier

The machine is designed for tunnel sections ranging from 4.5m × 4.5m to 7m × 7m and is suitable for a variety of underground mining applications.

Typical applications include:

· Mine development drifts

· Crosscuts

· Haulage tunnels

· Ventilation tunnels

· Service infrastructure development

The intelligent control system helps operators achieve consistent drilling quality while minimizing drilling deviations.

Significant Improvements in Drilling Accuracy and Advance Rates

Since commissioning, the equipment has demonstrated excellent performance in hard porphyry copper formations.

Project performance indicators show:

· 45% increase in monthly development advance

· Improved drilling accuracy

· Reduced overbreak and underbreak

· Better blasting fragmentation

· Lower explosive consumption

· Reduced operating costs

According to project engineers, the automated drilling functions have improved tunnel profile consistency and simplified operator training.

The equipment’s reliability has also contributed to high machine availability, ensuring uninterrupted development operations throughout the project.
