Accessories Required for DTH Drilling
The air compressor drilling uses high-pressure compressed air as the medium to blow rock fragments from the bottom of the hole through the annular space between the drill rod and the borehole wall, while also cooling the drill bit, relying on impact or rotation to break the rock. It is mainly used for rapid drilling construction of water wells, ground source heat pumps, photovoltaic piles, mine slope anchoring, and water-scarce arid strata. Using DTH drilling requires a compressor, a hammer (DTH), a DTH drill bit, drill rods, air pipes, and other accessories.
