Applications:
The down-the-hole drilling is used to produce large-diameter holes in rocks, usually in the initial stage prior to blasting, but it is also used in non-blasting applications. DTH drilling are used mostly in mining quarries but can be used in a variety of other construction applications. The DTH drilling method is growing in popularity, with increases in all application segments, including blast-hole, water well, foundation, oil & gas, cooling systems and drilling for heat exchange pumps. Applications were later found for the DTH method underground, where the direction of drilling is generally upwards instead of downwards.

Advantages and Feasures:
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.
