A water well drilling rig with DTH hammers outperforms others in hard rock drilling.
-
High efficiency: Frequent impacts break rocks directly. Drills 1-2m/h in granite, no energy waste from rotation.
-
Energy saving: Uses over 70% of impact energy, saving 20-30% power vs roller bits.
-
Strong adaptability: Works stably in fractured zones, reducing jamming risks despite rock cracks.
A mountain project drilled 120m in 20 days with DTH hammers. Traditional rigs would take 60 days.
These advantages make the water well drilling rig excel. The water well drilling rig thus handles hard rocks efficiently.
