DTH Drilling Method – Working of DTH

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