Comparison Of Hydrodynamic DTH Hammer With Conventional Rotary Drilling
Jun 28, 2018

Compared with conventional rotary drilling, hydrodynamic DTH hammer drilling has the following advantages:

(1) Make full use of the on-site routine ancillary equipment, basically does not change the existing operating rules;

(2) because the pump pressure is easy to reach a higher value, so the hydraulic hammer adapt to the hole deeper (has reached 5118m);

(3) The drilling time of hard rock stratum is high;

(4) The broken stratum is not easy to Center, and the back footage is long;

(5) Prolong the life of the bit effectively;

(6) to a certain extent to reduce the hole oblique strength;

(7) Low energy consumption and less environmental pollution;

(8) Not afraid of aquifer, strong wall protection ability; (9) Easy maintenance and convenient operation.
