What is a down-the-hole drilling rig

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]

What air compressor should be used with a water well drilling rig

Waterwell drilling is essentially drilling for underground water for agricultural and residential water needs. A perfect waterwell drilling setup would include: - A drill rig system which includes DTH hammer, DTH bit and drill tubes - Reliable skid mounted diesel air compressor. Waterwell drilling is essentially drilling for underground water for agricultural and residential water needs. A perfect waterwell drilling setup would include: - A drill rig system which includes DTH hammer, DTH bit and drill tubes - Reliable skid mounted diesel air compressor. When drilling a water well through the hard rock, no drilling method is as efficient as a DTH Hammer energized by the right air compressor providing high enough pressure. Softer grounds may also be drilled by air flushed rotary drilling, demanding a lower pressure air.. Air pressure requirement: The air compressor must provide sufficient air pressure to overcome the formation resistance encountered by the drill bit and maintain the drilling force. Typical air compressor pressures range from 7-30 bar (100-450 psi). [pdf]
