2. Increased Accuracy The DTH method offers superior hole quality, producing straighter boreholes with less deviation. This precision is vital for applications that require exact placement of blast holes or geothermal probes.
The main components of submarine hammer drilling equipment include the drill rig, hammer, drill pipes, and the drill bit. The drill rig is often mounted on a surface vessel or a floating platform and is designed to support the excessive weight and dynamic forces encountered during drilling operations.
