Underground development begins at the face, and precision starts with drilling. The GST SQD Drill Rig is the ultimate tool for modern mining operations, engineered to deliver superior results in even the most challenging conditions.

Available in hydraulic or pneumatic configurations, the SQD is designed to drill support holes, blast holes, and roof bolts with maximum accuracy and safety. Its unique rollover assembly allows for multi-directional drilling, ensuring adaptability in tight working environments.

Safety as Standard
With the operator more than six meters from the face and safely positioned under a canopy, the SQD keeps your personnel protected at all times. Operators work under permanent roof support, minimizing exposure to unstable ground. This reduces the risk of injury, especially in poor rock conditions, and contributes to a stable working environment for the entire development crew.

Quality That Delivers
The SQD’s controlled, disciplined drilling results in straighter holes and better fragmentation. This directly:
• Improves advance per blast
• Reduces explosive use
• Cuts down secondary support costs
• Increases development cycle, with rounds of up to 3.8 meters drilled successfully.
With double booms operating independently, drilling time is significantly reduced, while remotely drilling roof support further improve operator safety and skill development.

This is mining made safer, faster, and smarter.

After the drill rig completes its precise pattern, the mine’s blasting team initiates the next critical stage: blasting the face. This stage is all about controlled energy release, breaking the rock efficiently while maintaining stability and safety.

Thanks to the SQD’s consistent drilling patterns, blasts are more predictable and effective. The rock breaks cleaner, reducing overbreak and ensuring the hanging wall remains stable.

This results in:
• Improved fragmentation, which enhances loader efficiency
• Reduced damage to surrounding rock, lowering long-term support costs
• Minimized rework and misfires, saving both time and money

A well-planned blast, built on precision-drilled holes, sets the stage for the final act in the development cycle, the clean-up. That’s where the SQL Loader proves its worth.

Our machines come equipped with the latest safety features and are build to the highest standards possible. This isn’t just for show; it’s a commitment to providing a safe working environment. As the saying goes, "A happy worker is a safe worker," and we believe there’s a nugget of truth in that – pun intended!

A gold mine filled with safe operations is a mine that can flourish for years to come.

Once the blast is complete, it’s time to move ore, and fast. That’s the job of the GST SQL Loader, a rail-bound mucking loader engineered for speed, safety, and operational efficiency.

Designed for Safety
With the operator positioned more than three meters from the face and under a canopy, the SQL keeps personnel far from hazards. Like the SQD, the SQL operates entirely under roof support, meaning no team members are exposed to an unsupported hang wall.
There’s no need for sliding rails, and mechanical barring/dressing is done during the loading process, eliminating unnecessary manual work and keeping crews safer throughout.

Built for Results

The SQL Loader isn’t just safe—it’s a workhorse. It can:
• Clean a full round in under two hours, depending on hopper availability
• Load a hopper to full capacity in under 2 minutes
• Eliminate derailments, reducing rail maintenance costs
• Enhance working conditions, making mining jobs more sustainable and professional

By enabling longer rounds to be cleaned quickly, the SQL directly contributes to faster development rates. At the same time, it promotes skills development in a safer, more structured environment.

At GST, we are excited to be at the forefront of this evolution with our quality equipment that not only meets but exceeds the current mining expectations. Together with the mining community, we strive to unearth not only gold but also opportunities for growth, safety, and environmental responsibility. Who knew mining for gold could be this much fun?
