Experimental Study on the Anisotropy of the Tensile and Shearing Strength of Coal Rock
Bibliographic record
Abstract
The tensile and shearing strength of coal rock accurately obtained by test can provide important parameters for the design of coal seam fracturing and mine support system. Due to coal bedding and cleat developed, the experimental results will exist voluminous discreteness and can’t accurate determine the tensile and shearing strength, ignoring the influence of loading direction and bedding and cleat development direction, In this paper, the tensile and shearing strength is measured by laboratory experiment, counting and analyzing divergence of different direction according to experimental results, obtaining the relationship between the tensile and shearing strength and the bedding and cleat development direction. This research confirms that the tensile and shearing strength of coal rock exists the characteristic of anisotropy and it should not only take the average value of the test results of different direction simply in engineering application. On the other hand, it can supply experimental consideration and method to confirm the tensile and shearing strength required by the relevant construction design. Key words: Coal rock; Tensile strength; Shearing strength; Anisotropy

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
