Abstract

The invention relates to a method for creating a deep borehole, in particular in an emission-sensitive region, and to a device therefor. The invention is based on the object of providing a drilling method and a drilling device allowing deep boreholes to be created even in regions which are sensitive to emissions, such as inner-city buildings or in nature regions to be protected, and at the same time of reducing significant damage to these regions when creating deep boreholes. This object is achieved in that a shaft structure (20) is created, a stationary drilling system (10) is installed into the shaft structure (20), the floor (23) of the shaft structure is prepared as a drilling starting point and the deep borehole is sunk using a suitable drilling method.
