ZOOMLION DTH drill rigs deliver powerful drilling performance across open-pit mines, quarries and large-scale geotechnical projects. Built for blast hole drilling and other borehole drilling applications through different rock formations, these heavy-duty mining machines use a high-pressure, high-volume two-stage screw air compressor and a high-frequency down-the-hole (DTH) hammer to achieve faster penetration and consistent hole quality.

From soft rock to hard rock, operators can adjust the rotation speed to match the ground conditions and drilling requirements of open-pit mining operations. A crawler undercarriage gives these ZOOMLION down-the-hole drill rigs the mobility and traction needed to travel across rough, uneven terrain at demanding mining sites where drilling work continues day after day.
