6 FAQs about [Why is the down-the-hole drill drilling slow]

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 a down the hole hammer?

One of the most commonly used tools in the drilling industry to meet such challenging scenarios is the Down the Hole Hammer (DTH hammer). DTH hammers are most used in hard rock formations and are designed to tackle complex tasks like drilling in populated areas without putting existing structures at risk.

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.

Are DTH hammers good for drilling?

DTH hammers therefore offer drilling efficiencies with a high rate of penetration (ROP). This is down to the fact that the air-powered hammer consistently minimizes energy loss to the drill bit, allowing it to break down the rock efficiently.

Should you switch from Rotary to DTH drilling?

The data on industry from Mining.com shows that companies who make the switch from traditional rotary systems to DTH drilling see productivity gains that range from 30 percent due to increased drilling speeds, less bit wear, and increased efficiency of fuel.

Why should you use a DTH drill rig?

In the first place, DTH drill rigs are specifically designed to offer extremely high rates of penetration particularly in difficult rock conditions. Operators can complete boreholes faster, thereby cutting down on time spent in the machine and labor.
