Abstract
Rock bolts are the principal reinforcement element of many underground support systems. This thesis investigates and characterizes the behaviour and performance of rock bolts as measured by a pull test. A database composed of 985 pull tests from six mines in the Sudbury Basin was assembled. Procedures and apparatuses used to conduct these tests were compared to ASTM's standards and ISRM's suggested methods. The results from the pull tests were used to compare the behaviour of reinforcement elements with theoretical models and to quantify performance metrics and their distributions. The influence of bolt, installation and rock mass parameters on the performance of certain rock bolts was investigated, and distributions of expected behaviour were constructed. These may be used in the design of hard rock underground excavations using methodologies that incorporate both the load capacity and displacement behaviour of rock bolts.

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
