The water well drilling rig DTH hammer excels in deep wells (>100m) with these strengths:
-
Low energy loss:
Compressed air loses little in drill pipes. Oor 80%
impact energy remains at 100m.
-
Efficient cuttings removal: High-pressure air quickly clears cuttings, preventing excess sediment at the bottom.
-
Strong adaptability: Longer drill pipes extend drilling. With casing support, it handles complex formations.
A mine used a high-pressure DTH hammer for a 300m well. It overcame 6 hard rock layers, completing water extraction—50m³/h. The water well drilling rig performed reliably.
