• In the hole range 100-254 mm (4"-10"), DTH drilling is the dominant drilling method today (especially when the hole depth is greater than 20 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.
