Product Description

Underground Portable Rocks Air Percussion Drilling Rig

I. Descriptions:

The pneumatic DTH (Down-the-Hole) rock drilling machine with the turntable is powered by compressed air motor, and is mainly used for fan-shaped or annular medium-depth and medium-diameter blastholes in underground mining fields, and can also be used for underground anchors supporting. It can be used in hydro project in engineering drilling purpose. 

Turntable rocks drilling machine is a medium and deep hole rock drilling tool powered by compressed air. The medium-deep hole rock drilling equipment powered by compressed air is mainly used for the stonework engineering of the upward fan-shaped or annular medium-deep hole drilling in the underground mining field. It is suitable for drilling with a diameter of 50-80mm and a drilling depth of 30m. Using a cross-shaped alloy drill bit with a diameter of 65mm, the average pure rock drilling speed can reach 680mm/min in F12-14 grade ore. The drill frame is simple in structure, easy to dismantle and transport, and works well.

The sizes of different models of turntables are suitable for 2.2mx2.2m-2.7mx2.7m /  2.5mx2.5m-3.0mx3.0m
