D545H Φ115-138mm DTH mining Blasthole Drilling Rig

The RuiXin drill rig stands out for its ability to maintain high drilling efficiency while keeping energy consumption low. It perfectly meets the rock drilling requirements for holes with diameters of 115mm and 138mm, and this excellent balance between performance and operational costs gives it remarkable cost-effectiveness.

What’s more, it is equipped with a high-speed rotary feed solution, which is specially designed for soft rock operations like coal mining. In practical applications, this solution has shown impressive results. During coal mining operations in Inner Mongolia, it achieved a rock drilling speed of 3 meters per minute, significantly reducing the time needed for drilling each hole and effectively boosting the progress of the entire project.
