Abstract

fetched live from OpenAlex

In order to locate mined-out areas in gold mines and place a curb on its hidden hazard, through laying out two high precision gravity survey sections of the 1 : 100 scale in the research area, with Canadian Scintrex Corporation's CG-SAutoGrav gravimeter, the gravity anomaly data are measured by the high precision gravity survey method for the first time, and the inversion is made by the Euler deconvolution method to determine the collapse of the mined-out region and the stable sector. Our results indicate that the application of high precision gravity survey in the gold mine mined out area is effective, and the explanation of gravity anomaly data by the Euler deconvolution method is fast and highly effective with few artificial intervention.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
