DTH Hammer Drilling Advantages
DTH Hammer Drilling Advantages
(1) The cost is low. The down-the-hole hammer drilling requires small axial pressure on the drilling rig, low rotational speed, low torque, and low natural power consumption. The diameter of the drill pipe is relatively small, easy to install and disassemble, and has a long service life.
(2) The drilling efficiency is high, the life of the drilling tool is longer, the down-the-hole hammer drilling is used for rock drilling, the medium is air, and there is no problem of recovery and disposal of the flushing medium, which reduces the auxiliary time.
(3) In the stratum with serious leakage and unstable hole wall, the down-the-hole hammer drilling can be used to drill with the pipe to completely solve the problem of repeated operations.
(4) DTH hammer drilling, the hole wall is relatively complete, there is no pollution from other materials , the original formation structure and water permeability can be basically maintained, the well cleaning time is reduced, and the cost is saved.
(5) As the down-the-hole hammer uses wind as the power source, it is constructed in severe winter, which greatly reduces the workload of cold protection in previous winter construction.
