One of the advantages of this method is the lower initial investment cost and lower fuel consumption compared to other conventional methods. Extensive research has been conducted by drilling machinery manufacturers worldwide, among which Atlas Copco has conducted extensive research on optimizing the effective energy transfer process of shock waves from the drilling hammer to the drill head, resulting in the design of a new generation of drilling hammers with optimized piston length and equipped with a Damping Double damping system. The result has been an increase in drilling speed and rate, as well as the overall lifespan of the drilling rod. What limits this method is the power of the hammer blows of these machines, especially in holes with a diameter greater than 127 millimeters and a hole depth of more than 6 meters, as with an increase in hole depth, more drill rods need to be connected to each other, resulting in more energy loss in this drilling method. By examining the amount of energy loss due to the connection of consecutive rods in drilling machines operating with this system, it has been determined that the energy loss due to shock wave transmission for each additional coupling in the range of 6 to 10 percent, which is caused by imperfect contact in the connections of drilling rod couplings.
