Deviation to mucking analysis
Bibliographic record
Abstract
Deviations in drill holes during underground mining substantially impact operating efficiency and safety. An examination of six stopes at Thompson Mine revealed systematic deviations of roughly 1 m (3 ft) from the designated drill hole configuration. Excessive deviations may result in imprecise ore body targeting, elevated operational expenses, and possible safety risks. A correlation was identified between the percentage of holes deviating beyond the average and the mucking rate, indicating that to sustain an average of 544 tonnes (600 tons) per day, less than 21% of holes should surpass the average deviation. It is also essential that drill speeds average 9.14 m (30 ft) per hour, particularly for novice operators, to reduce hole deviation. Regulated drilling rates improve precision, resulting in more efficient and economical operations. Decreased drilling rates mitigate the likelihood of misalignment and structural complications. Efficient management of drill hole variations necessitates sophisticated drilling tools, meticulous planning, and ongoing monitoring to guarantee adherence to the designated drill trajectory. Mining operations can achieve improved resource recovery, decrease waste, and enhance production by limiting deviations. Mitigating drill hole deviations is crucial for enhancing underground mining projects' economic and environmental results, allowing for a degree of tolerance for systematic deviations.

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.
