Custom-tailored solutions for specific tasks: geotechnical solutions for mines and tailing storage facilities
Bibliographic record
Abstract
Planning and construction of new, and the rehabilitation of existing mines and tailings storage facilities, entails some challenges for mine operators, consultants and contractors when it comes to subsoil engineering. Site-specific conditions, technical requirements, geological conditions and numerous interfaces to other parts of the total system require individually tailored solutions for seepage barriers and ground improvement to generate an overall technically and economically optimised system for the specific task. Such kinds of specialist foundation engineering have been successfully carried out by BAUER for mines and tailings storage facilities in Europe, the Middle East and North America. Structural diaphragm wall shafts as deep as 120 m were installed at Woodsmith Mine (England). By comprehensive re-design, conventional shaft sinking methodology was replaced by an innovative foreshaft construction using circular diaphragm wall shafts. Plastic concrete cut-off walls with inserted sheet pile elements of considerable extent were constructed at Arab Potash Company (APC) Dike (Jordan). Through re-engineering, the originally considered single-phase system with self-hardening slurries was replaced by the two-phase system to construct a hybrid diaphragm wall made of sheet piles and plastic concrete, fulfilling both excavation support and cut-off function. A complex combination of several construction methods was applied at Diavik Diamond Mine A21 (Canada) to seal the new dike for open pit mining. Ground/soil improvement measures were executed at Red Dog Mine (USA) and at another mine in Canada. All these interventions were accompanied by comprehensive quality QA/QC and health, safety and environment measures to fulfil the strict conventions of the mining industry. Such foundation construction methods as described in the abovementioned case studies can be used at any time up to and including mine closure, to minimise the risks to the public, the environment, groundwater etc. posed by abandoned mines, and have been successfully used in the closure/enclosure of open cast coal mines in Germany and the encapsulation of former chemical industry sites.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
