You might’ve heard of a DTH drilling rig. It’s a highly efficient drilling machine. Simply put, it’s a down the hole drilling rig mounted on tracks. This design allows it to move easily in open-air conditions, which is why it’s also known as an open-pit DTH drilling rig.
DTH drilling rigs mainly come in two types: split and integrated. A split DTH drilling rig usually works with a separate, wheeled air compressor, which provides air through a hose. An integrated DTH drilling rig, however, has the air compressor built right into the machine, making it more compact. No matter the type, our DTH drilling rig delivers stable and reliable performance.
