The Coal Mine Pneumatic Deep Hole Drilling Jumbo is a compressed air driven, track-mounted, light duty drilling rig, used primarily in underground coal mines. Working with highly efficient spiral rods and carbide drill bits, it is widely used in coal mine projects such as gas detection hole drilling and water hole drilling.

The Jumbo is driven by compressed air. It is safe, and easy to operate. The Jumbo’s operation can be carried out by a single operator. During drilling work, it has more than 6kw output. Compact in size, the jumbo can work in a 1 meter wide tunnel. It is equipped with a locking system which improves the stability during operation.

A pneumatic lifting system allows the Jumbo to drill holes at different heights, ensuring quick and easy adjustments during operation.
