MEASUREMENT OF MOISTURE CONDITIONS FOR MINE WASTE STORAGE FACILITIES USING THE DEEP DIVINER MOISTURE PROBE
Bibliographic record
Abstract
There is a need to measure deep in situ moisture conditions for all types of waste storage facilities in a safe, cost effective, practical, and efficient manner. This paper describes the Deep Diviner moisture probe, a deep capacitance moisture sensor, which has been developed by the authors with the assistance of the Canada Industrial Research Assistance Program (IRAP). The deep capacitance moisture probe uses the Diviner 2000, a portable capacitance soil moisture monitoring sensor manufactured by Sentek Sensor Technologies. This portable probe was developed for irrigation management, and is a nonradioactive sensor. Development of the deep capacitance moisture probe involved modifying the Diviner 2000, which has a limited depth range of 1.6 m, to allow the measurement of volumetric water content to depths of 40 m or 50 m, and possibly deeper. A winch / cable assembly was developed to lower the sensor down within a PVC access tube to allow for fully automated measurement of in situ moisture contents at user specified depth intervals, each of which are recorded on a portable datalogger. The prototype of the deep capacitance moisture probe was tested both in the laboratory and in a full-scale field situation to ensure the required hardware modifications were functional. Full scale field testing was also completed on the prototype. The results of this testing show that the deep capacitance moisture sensor is capable of measuring the water content of till and sand materials to depths of 6 m. This paper describes the development and testing of the deep capacitance moisture. ______________________ 1 Paper presented at the 7 th International Conference on Acid Rock Drainage (ICARD), March 26-30, 2006, St. Louis MO.

How this classification was reachedexpand
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.
