Products Description
The RCZ412B-1 is a DTH drilling machine for mining designed for efficient drilling in medium-sized mines and extremely hard rock formations. It uses advanced down-the-hole hammer technology to achieve faster penetration rates in materials such as granite, basalt, and iron ore. The RCZ412B-1 DTH (Down-The-Hole) drilling machine is a high-efficiency rock drilling machine designed for medium-sized mining operations and extremely hard rock conditions. Utilizing advanced DTH hammer technology, it delivers 50% faster penetration rates in ultra-hard formations like granite and basalt (up to 300MPa compressive strength). Suitable for blast hole drilling, slope presplit holes, and precision anchoring projects, this lightweight rig combines flexibility with low operational costs, making it the top choice for optimizing blasting quality and reducing mining costs in challenging rock environments.

Key Features of DTH Drilling Machine for Mining
- High-pressure air drives the hammer to strike directly at the rock face, minimizing energy loss and maximizing impact force for 300MPa hard rock drilling.
- Dual-action rotation ensures straighter holes (±1° deviation) and smoother blasting control.
Switch freely between vertical and angled holes (0-90° adjustable) to ensure uniform rock fragmentation and eliminate blast toe.
- Auto-adjusting RPM, feed pressure, and air flow based on real-time rock hardness data, reducing bit wear by 30%.
- Modular design cuts fuel consumption by 20% compared to traditional rigs.
Application
In hard rock open - pit mining, RCZ412B-1 DTH drilling machine efficiently drills through tough materials like granite, iron ore, and volcanic rock for bench drilling, facilitating smooth mining operations. For slope engineering and safety, it conducts presplit drilling to control blast damage, drills anchor holes for slope stability, and creates drainage holes to manage water runoff. And it provides cost - effective blasting solutions by precisely drilling holes, maximizing explosive effectiveness, reducing explosive usage, and improving blasting quality, thus saving costs for mining and construction projects.
DTH Drilling Machine vs Traditional Rotary Drill Rig
| Item | RCZ412B-1 DTH drill rig | Traditional rotary drill rig |
| Hard rock penetration | 300MPa High-efficiency penetration of extremely hard rock | Relying on rotary cutting, and hard rock efficiency drops sharply |
| Energy consumption and cost | Directly driven by high-pressure air, low energy consumption and low maintenance cost | Relying on hydraulic/electrical systems, high energy consumption |
| Drilling flexibility | Supports drilling at any angle, adapting to complex blasting designs | Mostly limited to vertical drilling |
| Applicable scale | Economical choice for small and medium-sized mines, fast return on investment | Dedicated for large and medium-sized mines, high initial cost |
