Abstract
Stress measurement is the key step in mine design. It plays an important role when seismicity and rockbursting are expected to be major risks during project construction or mine operation. Mini-frac testing is commonly conducted for in situ stress measurement in the early stages of mine design studies before excavations are available. This paper presents the results of a series of mini-frac tests conducted at 350–750 m depth in a vertical borehole at the KGHM International Victoria Project in Sudbury, Ontario, Canada. Stress correlations were obtained using mini-frac test data and borehole breakout studies. The minimum stress orientation is vertical and gravity induced. The intermediate principal stress is horizontal with a kh (ratio of intermediate to vertical stress) equal to 1.41. For the maximum principal stress, two kH (ratio of maximum to vertical stress) values of 2.08 and 2.42 were found, based on two possible pore pressure scenarios. The estimated magnitudes of the principal stresses were also extended to depth based on borehole breakout analysis. The mini-frac test results and borehole breakout analysis achieved reasonable agreement. The borehole breakout images indicate that the maximum principal stress trend is N80E.

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
