FAQ:
1. What is DTH hammer?
Down-the-hole drilling (DTH) essentially involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air. These active elements combine to be efficient at crushing rock.
2. What is hole hammer?
A pneumatic down-the-hole (DTH) hammer is a pneumatic drilling tool that is powered by compressed air. It can be used to drill in pebble, gravel, and hard rock layers. It is frequently employed in the construction of building pile foundations, bridges, mining, geological research, hydrological wells, and other fields.
3. Is top hammer drilling vs down-the-hole drilling?
The fundamental distinction between top hammer and down-the-hole drilling methods is the location of the hammer. During the down-the-hole drilling method, the hammer in the industrial equipment makes contact with the bit. The action of the top hammer drilling method is concentrated at the very top of the drill string.
