August 2025 – Wuxi, China — SINOCOREDRILL, a global provider of geological drilling equipment, has officially unveiled the UN1000 Tunnel Core Drill Rig, a new-generation intelligent hydraulic drilling system engineered to deliver superior performance in underground and tunnel drilling applications. Designed as a powerful alternative to imported equipment, the UN1000 combines advanced automation, compact structural design, and exceptional reliability, marking a significant leap forward for China’s high-end underground drilling technology.

As global mining investment and underground development continue to rise, demand for intelligent and efficient tunnel drilling equipment has accelerated. The launch of the UN1000 demonstrates SINOCOREDRILL’s strengthened capability to supply world-class drilling solutions suitable for complex mine environments.

Revolutionary Automation System Enhances Safety and Productivity

At the core of the UN1000 is its intelligent power head chuck and holder linkage system, designed to synchronize all drilling actions with minimal human involvement.
Through a single integrated control handle, operators can easily perform:

Make-up

Break-out

Rapid feeding

Rapid retraction

The built-in floating function protects drill rod threads from damage, significantly reducing drilling tool wear and improving long-term operational stability.

Compared with traditional tunnel drill rigs requiring multiple coordinated manual actions, the UN1000’s streamlined operation dramatically reduces the risk of drill rod falling, enhances safety, and shortens operational learning curves for new operators.

Three Smart Operation Modes for Tunnel Conditions

The UN1000 introduces three automated construction modes tailored for narrow, humid, and low-clearance tunnel spaces:

Drilling mode

Rod feeding mode

Rod retrieving mode

Each mode enables the chuck and holder to automatically coordinate movements according to the selected procedure, doubling operational efficiency compared with conventional rigs.
Early adopters report that the entire drilling cycle time has been reduced by up to 50%, representing a significant improvement in underground exploration productivity.

Bidirectional Pressure System for Complex Geological Conditions

Traditional underground drilling equipment relies on single-directional pressure systems, often leading to instability when drilling in fractured formations or in upward boreholes.
The UN1000 solves this issue through its bidirectional pressure main cylinder, ensuring:

Stable penetration in fractured or mixed formations

Reliable upward drilling performance

Smoother drilling with reduced vibration

No need for additional counterweight

This advanced pressure technology is considered a major breakthrough for underground core drilling systems.

Reinforced Structure and High-Durability Components

To withstand the harsh conditions of tunnel drilling, the UN1000 features a fully enhanced mechanical and hydraulic structure:

● Dual-rod mast structure

Provides equal pulling and pushing forces, ensuring stable performance and low maintenance requirements.

● Long-life nitrogen spring holder

Hydraulically opened and clamped, with a lifespan of up to 1,000,000 cycles, drastically reducing maintenance frequency.

● Heavy-duty power head

Enlarged bearing system for higher load capacity

Fully enclosed gearbox suitable for 360° drilling

Quick-replace slips for B, N, and H rods

Spring-clamped, hydraulically-released chuck design eliminates oil leakage problems common to capsule-type chucks

● Comprehensive safety protection

Including:

Protective safety nets

Multiple electronic fail-safe protections

Low-pressure pilot control system

Automatic safety logic for chuck–holder coordination

These features allow the UN1000 to operate safely even in confined and hazardous underground environments

Optimized for Multiple Underground Applications

With its compact size and robust adaptability, the UN1000 supports 0–180° all-angle drilling and is suitable for:

Underground mine exploration drilling

Drainage and dewatering boreholes

Ventilation and service holes

Grouting and reinforcement drilling

Tunneling geological prediction

Stabilization and support engineering

Its 3.8-meter chassis allows easy mobility and operation in small-section tunnels commonly found in global metal mines.

A Major Step for China’s High-End Tunnel Drilling Equipment

The introduction of the UN1000 aligns with the global trend toward intelligent mechanized mining.
Historically, many mining companies relied on imported tunnel drill rigs, resulting in high maintenance costs and long spare-part lead times.

The UN1000 represents a pivotal shift by offering:

Performance comparable to international brands

Lower operating and maintenance costs

Local spare-part availability

Faster customization for varied tunnel environments

“SINOCOREDRILL will continue to develop advanced drilling technologies that support global mining customers,” said the company’s chief engineer. “The UN1000 sets a new performance benchmark in underground drilling, enabling safer, faster, and more sustainable mine development.”

Conclusion

The launch of the UN1000 Tunnel Core Drill Rig marks an important advancement for SINOCOREDRILL and the underground drilling industry. With its intelligent hydraulic control system, automated linkage functions, enhanced structural durability, and superior adaptability to complex geology, the UN1000 delivers the safety, efficiency, and reliability that modern mines demand.
