Compact Underground Development Drill Rig Supports Gold Mine Development in Indonesia

Single-Boom Jumbo Drill Improves Tunnel Excavation Efficiency in Southeast Asia’s Mining Industry

INDONESIA, March 2026

A compact single-boom underground development drill rig manufactured by our company has recently entered operation at a major underground gold mining project in Indonesia.

The machine is being used for underground tunnel development, exploration drifts, access ramp excavation, and mine infrastructure construction, supporting the customer’s long-term production expansion plans.

The successful project demonstrates the growing demand for reliable underground drilling equipment in Southeast Asia’s mining sector.

Rising Demand for Underground Mining Equipment in Indonesia

Indonesia is one of the world’s leading producers of gold, copper, and nickel resources. As mining operations move deeper underground, mine operators increasingly require advanced drilling solutions capable of delivering higher productivity and lower operating costs.

The customer operates a large underground gold mine located in a challenging tropical environment characterized by:

· High humidity

· Elevated underground temperatures

· Narrow tunnel profiles

· Continuous multi-shift production schedules

To improve development efficiency, the customer sought a compact and highly maneuverable jumbo drill capable of operating in restricted underground spaces.

Compact Design Optimized for Narrow Underground Workings

The selected underground development drill rig was specifically engineered for small and medium-sized tunnel applications.

Key features include:

· Compact articulated chassis

· High-performance hydraulic rock drill

· Automatic drilling control functions

· Excellent maneuverability

· Low maintenance requirements

· Tunnel coverage from 2.5m × 2.5m to 5m × 5m

The machine’s compact dimensions allow it to navigate narrow mine drifts while maintaining high drilling performance.

Its hydraulic drilling system provides efficient penetration rates in hard rock formations commonly encountered in underground gold mining operations.
