In the Eurocode series of European standards (EN) related to construction, Eurocode 7: Geotechnical design (abbreviated EN 1997 or, informally, EC 7) describes how to design geotechnical structures, using the limit state design philosophy. It is published in two parts; "General rules" and "Ground investigation and testing".
This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
The management of borehole data is very different from non-borehole data. Specifically, borehole data requires a relational database management system (e.g. Access, FileMaker, SQL , Oracle ,) whereas non-borehole data (with the exception of land ownership) can be handled with simple “flat” file managers (e.g. Microsoft Excel , Lotus 1-2-3 ).

Borehole Mining (BHM) is a remote operated method of extraction (mining) of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jetting (hydraulicking). This process is carried-out from a land surface, open pit floor, underground mine or floating vessel through pre ...
A borehole shall be advanced incrementally to permit intermittent or continuous sampling. Intervals are typically 1.5 m (5 ft) or less in homogeneous strata. Tests and sampling should be done at every change in strata. After the borehole has been advanced to a desired depth and excess cuttings have been removed, testing and sampling can be ...
The Kola Superdeep Borehole was a similar project of the USSR in the 1970s and early 1980s the USSR attempted to drill a hole through the crust, to sample the Mohorovičić discontinuity. The deepest hole ever drilled failed not because of lack of money or time, but because of rock physics at depth.
