Abstract
The Nanisivik Mne is located on the 73rd parallel in the Canadian Arctic. The mine began commercial production in 1976 and has since produced over 16 million tonnes. The Main Ore Zone stretches for 3.5 km west to east and has an average width of 80 m with a height of 5–20 m. The room and pillar mining method was employed in the Main Ore Zone with approximately 800,000 tonnes remaining in pillars. During 1999, post pillar recovery commenced as an integral part of the annual mine production. Preparation for post pillar recovery was initiated a decade ago with a three phase study that addressed ground stress determinations, ground stability evaluation and a pillar recovery trial The major pillar recovery program commenced after Breakwater Resources acquired the mine in 1996. Tools such as the PIN (pillar index number) system and GMM (ground movement monitors) were developed and implemented to assist in the ground control aspect of post pillar recovery. This paper reviews the post pillar recovery plans as well as the monitoring systems utilized to ensure maximum pillar recovery coupled with maximum safety for the employees.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
