Siton KQDT-125 is a compact down-the-hole (DTH) drilling rig designed for drilling large, long and downward holes with high demands on hole straightness in mining. This DTH rig is suitable for drifts with a cross-section ranging from 3.3 to 4 m and can be effectively applied in sublevel stopping mining method. The powerful drilling rig comes with a rotatable beam, a DTH hammer, and four-wheel-drive, enabling flexible operation in confined underground spaces.

Features & benefits

1. Drilling System

Equipped with a hydraulic stabilizer mechanism, the drill beam ensures hole deviation of ≤1%, suitable for drilling holes with diameters of 120–254 mm and depths up to 100 m, ensuring precise and stability. The drill beam can rotate 360°and tilts from -10°to 55°, enabling multi-angle drilling. The rotary head features stepless speed control, allowing operators to adjust drilling speed according to varying rock hardness, which greatly enhances efficiency and adaptability.

2. Robust Chassis

The four-wheel drive system enables 360° on-the-spot steering. For long-distance tramming, the brakes can be released so it can be towed by other vehicles, ensuring fast and efficient operation. Equipped with lifting outriggers and a rear swing axle to improve operational stability.

3. Remote Control System

Equipped with an advanced remote-control system, it enables precise control of tramming and drilling operations from a distance, significantly enhancing operational safety. Even in hazardous or dusty environments, operators can stay at a safe distance to reduce risks.

4. Flushing System

The efficient down-the-hole rig features a high-efficiency flushing system that enables operators to quickly clear dirt, dust, and debris from the machine. Regular flushing helps prevent residue buildup that could cause wear or blockages, thereby extending service life, lowering maintenance costs, and ensuring long-term reliable operation.
