Abstract

fetched live from OpenAlex

Abstract The 500.000 t/a underground Mittersill scheelite mine produced around 12 Mio. t during its 40 year lifetime. The active western field dips with 55° to the NNW under the western flank of the steep valley. The ore zone is developed over a vertical length of 600 m from its outcrop at 1.250 m down to the 650 m asl. The deepest workings are already more than 1.000 m below surface due to the dipping below the mountain range. Open stoping with backfill, cut and fill as well as sublevel caving are the prominent mining methods. End of 2015 a micro seismic system from Canadian ESG Solution was installed to get a better understanding of induced stresses and movements in rock formation. As of December 2015 the system consisting of ten sensors are constantly recording all microseismic events in the mine at a depth between 500 and 1.000 m. The events are analysed and graphically displayed according their location, magnitude and category. Der Mittersiller untertägige Scheelit Bergbau gewinnt pro Jahr etwa 500.000 t Erz. Über die Lebensdauer des Betriebs wurden bereits mehr als 12 Mio. t abgebaut. Die derzeit im Abbau befindliche Lagerstätte, das sogenannte Westfeld fällt mit etwa 55° noch NNW unter den Hang ein. Die Lagerstätte ist vom Ausbiss auf dem Niveau 1.250 m NN bis zum Niveau 650 m NN über 600 Höhenmeter aufgeschlossen. Durch das Einfallen unter den Hang haben die tiefsten Grubenbaue bereits eine Überdeckung von über 1.000 m. Als Abbauverfahren kommen großräumiger Weitungsbau, Firstenstoßbau und Teilsohlenbruchbau zur Anwendung. Ende 2015 wurde ein mikroseismisches Überwachungssystem der kanadischen Firma ESG Solutions installiert, um ein besseres Verständnis über die durch den Bergbau hervorgerufenen Spannungsverlagerungen und Bewegungen im Gebirgsverband zu bekommen. Seit Dezember 2015 erfolgen die Aufzeichnungen in einem Bereich mit einer Überdeckung von 500 bis 1.000 m. Das System erfasst mithilfe von zehn Sensoren seismische Aktivität und zeichnet diese kontinuierlich in Echtzeit auf. Die Ereignisse werden nach Ort, Größe und Kategorie ausgewertet und dreidimensional grafisch dargestellt.

Teacher imitation

Not 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.
