Rotary Percussion Drilling
There are two kinds of rotary percussion drilling methods.
1) Top Hammer and
2) Down-the-hole hammer.
Down the Hole Hammer and Bits
A down-hole hammer is a percussion hammer drill. In this type of drilling the hammer and the bit are located at the end of the drill string. As the name implies, this hammer works "down the hole".
One of the main advantages of the DTH hammer is that the drilling rate is not affected very much by the length or depth of the hole as the percussive action takes place on the bit by the piston located within the hammer. DTH Hammers are well suited for drilling into medium-hard to hard rock. They are especially well suited for drilling into fractured rock. They are extensively used in mining, quarrying, civil engineering, and water well drilling industries.
