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. The system is thought to have been invented independently by Stenuick. Origin of the nameDTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes. .
In DTH drilling, the percussion mechanism – commonly called the hammer – is located directly above the drill bit. The drill pipes transmit the necessary feed force and rotation to the hammer and the bit, along with the flui. .
A is first thought to have been used for rock drilling in 1844. Many quarries used hand held tools that required the driller to suspend himself from a rope over the quarry face in order to place the drill hole in. [pdf]

Sinkholes develop when soft rock underground—e.g., limestone, gypsum, or other carbonate rock—wears away over time. This is known as “karst” terrain. Eventually, the unsupported sediment above the underground hole collapses, leaving the sinkhole. [pdf]
Drilling a hole in a wall may seem like a daunting task. Fortunately, this job is reasonably simple if you take a few basic precautions and use the right tools. Before you start, pick the appropriate bit for the type of wall you are drilling. You’ll also need to pick a good spot to drill your hole, away from any electrical. [pdf]

[FAQS about Baiyin non-excavation pilot drilling rig project]
DTH is short for “down-the-hole”. Since the DTH method was originally developed to drill large-diameter holes downwards in surface-drilling applications, its name originated from the fact that the percussion mechanism followed the bit down into the hole. Applications were later found for the DTH method underground, where the direction of drilling is generally upwards instead of downwards. [pdf]
