Abstract
Mixtures of waste rock and tailings are compared with unmixed waste rock and tailings in a column study of self weight consolidation. Standard practice for surface mine waste disposal produces the two individual waste streams of waste rock and tailings. Waste rock dumps offer high strength and low compressibility characteristics but are prone to oxidation and metal leaching because of their high permeability and unsaturated conditions. Tailings deposits typically have low permeability and slow time rate consolidation properties but also have end land use issues and long term stability problems related to shear strength. Three mixtures of waste rock and tailings were loaded into columns and monitored for settlement, drainage, and pore-water pressure response for 100 days. A fourth column was built with waste rock only as a control. Mixtures with approximately 5:1 waste rock to tailings by dry mass were found to have a hydraulic conductivity similar to tailings alone and total settlements similar to waste rock alone. Mixture materials also remained saturated during the 100 day test. Results indicate that mixing waste rock and tailings for disposal is a promising idea that may help eliminate problems arising from current practices in mine waste disposal.Key words: co-disposal, hydraulic conductivity, self weight consolidation, tailings, waste rock.

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
