  • the arrangement of a sensor for determining the physical and / or chemical properties of the soil directly in the drill head of a drilling device means that the drilling processes can be controlled more optimally, since measured values are now available directly from the driving area of the drill head.
  • the current driving conditions in the rock or soil can be taken into account accordingly and, for example, the driving, the speed of the drill head can be controlled accordingly and the drilling suspension can be continuously adapted.

Since the soil temperature is relatively constant, an increase in temperature is primarily attributable to an increase in friction at the drill head. Correspondingly, an intensified wear of the drill head can then be counteracted by intensifying the flushing or actuating actuators.
  • Optimal control of the drilling process can be achieved if the drill head has sensors for measuring the back pressure of the soil in the borehole, the grain number and size of the dissolved rock material, the viscosity of the drilling fluid, the pH value of the drilling fluid, the temperature and the flow rate of the Has flushing.
