Abstract
Recent measurements and observations suggest that moisture and particulate drawn through the return air raise systems which ventilate underground mines can cause rapid clogging and degradation of the outlet silencers, if not properly accounted for in the design of the system. The implications of this are multifaceted, and include significant economic, environmental, and residential annoyance concerns. This paper will present measured source and receptor based sound level data collected as part of a residential complaint investigation, outline specific elements which can be considered when designing a return air system to optimize the potential of the noise control equipment, and will examine the feasibility of implementing atypical noise control methods.

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 it
