6 FAQs about [How to install the air pipe of a down-the-hole drill]
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.
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.
How does air drilling work?
When drilling with air, the cuttings are carried up the annular space around the drill pipe by the bouyant effect of the air rushing to the surface. The benefits of drilling with air over mud is the faster speed of lifting the cuttings to the surface. Recommended bailing velocity ofr air drilling is 3,000 – 7,000 feet per minute.
How does air rotary drilling work?
In air rotary drilling, compressed air creates a mixture of air and drilling fluid (often water or drilling mud). This mixture is then pumped down the drill pipe to the drill bit, which assists in cutting through the formation and carrying the cuttings back to the surface. What are the Key Advantages of Air Rotary Drilling?
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.
Can a hammer be used to drill a hole?
When drilling holes in water-bearing rock, never leave the ham-mer at the hole bottom with the air supply switched off. If drilling is to be suspended temporarily, always pull up the hammer by at least two pipe lengths. Clean around the driver chuck before changing the drill bit. Make sure the shank of the new drill bit is clean.
