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]
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 the required position. This system used small diameter holes and was not only terribly inefficient, but very dangerous due to flying rock as a result of the inaccuracy of the drilled borehole. [pdf]

Sandvik has created its new Top Hammer XL to deliver the benefits of top hammer drilling as a viable alternative to down-the-hole (DTH) drilling. The new drilling system, designed for quarry and surface. [pdf]
These hammers use a low air pressure range of around 12 to 18 bar, which is significantly lower than the pressure used by conventional high-pressure DTH hammers. This means that they produce less noi. [pdf]

The Mozambique drill, also known as the failure drill, failure to stop drill, or informally as "two to the body, one to the head", is a technique that requires the shooter to fire twice into the torso of a target (known as a or hammered pair to the center of mass), and follow up with a more difficult shot to the head that, if properly placed, should kill or otherwise stop the target if the previous shots failed to do so.
