Is down the hole drilling safe?

Thankfully, we live in the modern era, where down the hole (DTH) drilling has become one of the most efficient and safest methods since its invention in the mid 1950s. Let’s explore what DTH drilling is, why it’s such a successful technique, and how it might be the perfect process for your drilling operation.

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.

Should a driller switch from Rotary to DTH drilling?

It’s important for a driller transitioning from rotary drilling to DTH drilling to know that they need to slow down the rotation speed on the rig. Faster rotation does not equate to increased penetration rates. The DTH hammer method is intended to crush new rock with every index of the rotating bit face.

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.

How much oil should a drill Hammer use?

On occasion, excess oil will drain down the drill rods into the hammer when it is not in use, and may demand a cleaning of the parts. Also, when using the hammer in cold and wet conditions, place it as far into the hole as possible to take advantage of ground heat. If parts are new, use an extra quart of oil per new joint of drill pipe.
