A down-the-hole drill, usually called DTH Drilling Rig, is basically a mini jackhammer screwed on the bottom of a drill string. The speedy hammer activity breaks hard stone into little flakes and dust and can be dismissed evident by the air exhaust in the DTH hammer.

The KT15C integrated down the hole drill rig for open use can drilling vertical, inclined and horizontal holes, mainly used for open-pit mine,stonework blast holes and pre-splitting holes. It is driven by the Cummins China stage III diesel engine and the two-terminal output can drive the screw. .
Down-the-hole drilling (DTH) essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation, and air. These active elements combine to be efficient at crushing rock. As the drill string slowly rotates, the. .
Unlike traditional mining drill rigs, DTH drilling equipment operates by utilizing a pneumatic pressure system where the hammer is positioned down the hole and directly impacts the drilling bit. This technique reduces energy loss and increases penetration rates, making it highly effective in mining.
[pdf] A common drill rig used for "Shot Hole Drilling" is the L.I.S (Low Impact Seismic) mounted on track carrier for operation in cut lines or environmentally sensitive area. Truck mounted drill or 4X4 buggy are utilized in the prairies. These drill rigs use water or air to assist the drilling.
