Hydraulic Down-the-Hole Drilling

What is a hydraulic driven DTH hammer drill?

Pneumatically driven DTH hammers are widely spread and known in the industry, however a hydraulic driven DTH hammer drill is still a challenge. The DTH hammer is positioned at the end of the drill string, it is screwed to the drill rod which delivers a drilling fluid powering the hammer mechanism.

How does a down-the-hole drill work?

Down-the-hole drilling is to drive the hammer behind the drill bit by compressed air by means of the drill pipe. The piston strikes a little bit straight, while the hammer external cylinder provides direct as well as steady guidance of the drill a little bit.

What is down-the-hole (DTH) drilling?

Down-the-hole (DTH) drilling has made it easier for contractors to drill wells faster and more efficiently, and to transition from dirt boring to rock boring just by adding a compressor and hammer to the drill bit.

Why do you need a down-the-hole drill machine?

A good equipment will not just do the job, it does better, quicker and at a lower cost. In the case of drilling through hard rocks it is this Down-the-Hole (DTH) drill machine has established itself as a reliable workhorse in the industry.

What is DTH drilling?

Down-the-Hole (DTH) drilling is a percussion drill technique that changed the way companies take on the process of boring rock. Instead of utilizing the hammer mechanism on the top of the drill string, as in the traditional rotary system, DTH technology places the Hammer directly in front of the drill bit.

What is a DTH drill rig?

DTH Drill Rig: The DTH drill rig is a powerful, mobile machine that serves as the core equipment for DTH drilling operations. It is equipped with the necessary power to operate the DTH hammer and drill bits. These rigs are often mounted on either tracked or wheeled chassis, providing high mobility across various terrains.
