KJ311 Underground Mining Drill Rigs and Tunneling Jumbo to tunneling operation at the section of 12-35m2 in hard-rock mine. The drill boom has optimal section covering shape and the propelling beam rotates for 360 degrees and automatically levels off for easy location of the drill hole. Meanwhile, the drill boom is also used for rock cross-cut and drilling with anchor rod.

The tunneling jumbo is arranged to provide good field of view for the driver. Four-wheel drive articulated chassis ensures that the tunneling jumbo travels flexibly, fast and safely in narrow roadway.
