6 FAQs about [Down-the-hole drill big hole 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.
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.
What is DTH hammer deep-hole drilling?
Against this backdrop, large-diameter DTH hammer deep-hole drilling technology has emerged as a game-changer, offering unique advantages and quickly gaining recognition in the mining industry. This technology significantly improves drilling efficiency, reduces costs, and provides robust technical support for sustainable resource development.
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.
What makes a DTH drill system different from other drilling systems?
The advent of tungsten carbide for the drill bits (the first bits were all-steel) and the development of the button drill bit coupled with the introduction of high air pressures (25 bar plus) has meant that the DTH system can compete easily and efficiently with other drilling systems.
What is the difference between air rotary and down-the-hole hammer?
The differences between the air rotary system and this drilling system are primarily the cutting action and the resulting cuttings, as shown. 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.
