In the hole range *****4 mm (3"**0"), DTH
drilling is the dominant drilling method today
(especially when the hole depth is greater than *0 meters). The
main features of DTH drilling in this hole range are:
• Excellent hole straightness within 1.5% deviation without
guiding equipment.
• Good hole cleaning with plenty of air for the hole cleaning
from the hammer.
• Good hole quality with smooth and even hole walls for easy
charging of explosives.
• Deep hole drilling capacity with constant penetration and no
energy losses in joints.
• Efficient energy transmission.
• The disturbance to the ground is kept minimum, and for drilling
rock, the penetration rate is outstandingly high.
• More cost-effective than the conventional rotary drilling.
