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.
Third, the structure of the drilling rig:
The drill tool is composed of drill pipe, ball tooth drill bit and impactor. When drilling, two drill rods are used to drill. The reverse air supply structure is composed of a reverse motor, a reverse reducer, and a reverse air supply inverter. The reverse reducer is
