D545T Φ115-138mm Integrated Down The Hole Dth Drill Rig

While maintaining high drilling efficiency and low energy consumption, the [equipment/model name] is well-suited to meet rock drilling requirements for holes with diameters of 115mm and 138mm. This balance of performance and resource efficiency gives it a distinct edge in cost-effectiveness, making it a practical choice for projects seeking both operational productivity and budget control.

Notably, it features a high-speed rotary feed solution specifically optimized for soft rock operations—such as coal mining scenarios where rock hardness is relatively low. In actual application cases, it has achieved an impressive rock drilling speed of 3 meters per minute during coal mining operations in Inner Mongolia, a performance that significantly shortens single-hole construction time and effectively boosts overall project progress.
