6 FAQs about [Down-the-hole drill material video]

What is a down-the-hole drill?

A down-the-hole drill, usually called DTH by most professionals, is basically a jackhammer screwed on the bottom of a drill string. The fast hammer action breaks hard rock into small cuttings and dust that are evacuated by a fluid (air, water or drilling mud). The DTH hammer is one of the fastest ways to drill hard rock.

Why do you need a down-the-hole drilling tool?

Down-the-hole drilling tools are capable of delivering high-performance results in various geological conditions, ensuring reliable and efficient water well construction. This makes them a preferred choice for ensuring access to clean and sustainable water sources.

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.

How do you drill a rock with a DTH hammer?

This method is mainly applied for hard to very hard rock and/or for penetrating large boulders. 1. Setting the DTH hammer with drill rod and casing on the drilling point. 2. Rotary and percussive drilling of the drill string under compressed air supply. 3. After reaching the final depth, unlocking of the drill rod with DTH hammer and pilot bit.

How does a down-the-hole hammer work?

The down- the-hole hammer uses the rotary percussion cutting action through the use of a button bit. This system is best suited for well consolidated formations, offering excellent penetration rates. Compressed air provides the percussive energy to power the hammer. The resulting exhaust removes the cuttings. Note the quality of the cuttings.

Where is the hammer located in DTH drilling?

In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the fluid (air, water or drilling mud) used to actuate the hammer and flush the cuttings.
