The invention relates to a method for creating a deep borehole, particularly in an emission-sensitive region, and a device therefor. The invention is based on the object of providing a drilling method and a drilling device, by means of which deep boreholes can be created even in regions that are emission-sensitive, such as in inner-city building development, or in protected nature regions, while simultaneously reducing significant damage to said regions when creating deep boreholes. Said object is achieved in that a shaft structure (20) is created, a stationary drilling system (10) is installed into the shaft structure (20), the base (23) of the shaft structure is prepared as a drilling starting point, and the deep borehole is sunk using a suitable drilling method.
L'invention concerne un procédé pour l'exécution d'un sondage, en particulier dans une zone sensible aux émissions, et un dispositif correspondant. L'invention a pour but de disposer d'un procédé de forage et d'un dispositif de forage permettant d'exécuter des sondages, y compris dans des zones sensibles aux émissions, telles que des zones construites au centre ville ou dans la nature à protéger, et tout en réduisant, en même temps, des influences nuisibles pour lesdites zones lors des sondages. Ce but est atteint grâce à l'invention, laquelle est caractérisée en ce qu'un puits (20) est édifié, une installation de forage stationnaire (10) est construite dans le puits (20), la base (23) du puits est agencée en tant que point de départ du forage, et le sondage est foré suivant un procédé de forage approprié.
