DTH Drilling Method – Working of DTH
- In DTH drilling, the percussion mechanism commonly called the hammer is located directly behind the DTH drill bit.
- The drill pipes transmit the necessary feed force and rotation to the hammer and bit plus compressed air or fluids for the hammer and flushing of cuttings.
- The drill pipe is added to the drill string successively behind the hammer as the hole gets deeper.
- The piston strikes the impact surface of the bit directly, while the hammer casing gives straight and stable guidance to the DTH drilling bits.
