Bohrkellerdurchmesser

Bohrkellerdurchmesser refers to the diameter of the bore hole created during drilling operations, specifically in underground or subterranean contexts often associated with mining, tunneling, or geotechnical investigations. This measurement is crucial for determining the suitability of a borehole for various purposes, such as inserting pipes, cables, or geological survey equipment. The term originates from German, where "Bohr" means bore or drill, "Keller" translates to cellar or basement, and "Durchmesser" signifies diameter.

The bohrkellerdurchmesser is a fundamental parameter that influences the choice of drilling equipment, drilling techniques, and the materials that can be subsequently installed within the borehole. It is directly related to the type of drill bit or reamer used and the geological strata being penetrated. Different applications require specific borehole diameters. For instance, a borehole for a small-diameter monitoring well will have a much smaller bohrkellerdurchmesser than one intended for a large-diameter tunnel boring machine.

Accurate measurement and control of the bohrkellerdurchmesser are essential for project success. Deviations from the planned diameter can lead to difficulties in installation, structural instability, or operational inefficiencies. In geotechnical engineering, the bohrkellerdurchmesser is also important for understanding the in-situ stress conditions and for the design of support structures. This parameter is a standard specification in drilling contracts and technical documentation for underground construction and exploration projects.
