Abstract
В промышленных условиях карьера «Эльдорадо» ООО «Соврудник» были проведены инструментальные замеры скорости детонации промышленного эмульсионного взрывчатого вещества НПГМ-100 и НПГМ-70 для анализа детонационных характеристик ВВ и установления их соответствия требованиям технических условий. Измерения проводились в технологических скважинах при производстве массовых взрывов в карьере, с использованием иностранного оборудования DataTrap II Data/VOD Recorder канадской фирмы «MREL Group of Companies Limited», в основе которого заложен современный вариант реостатного метода измерений (резистивный метод). В результате исследования установлено, что введение в состав ПЭВВ НПГМ сухой фазы около 30 % (при r=1,2 г/см) способствует увеличению скорости детонации ВВ. Также измерения показали рост детонационных характеристик ВВ при снижении его плотности до значения r=1,17 г/см. Следовательно, с понижением плотности до нормальных значений (r=1,16 - 1,17 г/см) можно ожидать скорость детонации, которая заявлена в технических условиях. N the industrial conditions of the Eldorado quarry, OOO Sovrudnik, instrumental measurements of the detonation velocity of the industrial emulsion explosive NPGM-100 and NPGM-70 were carried out to analyze the detonation characteristics of explosives and to establish their compliance with the requirements of technical conditions. Measurements were made in technological wells during the production of mass explosions in the quarry, using foreign equipment DataTrap II Data/VOD Recorder of the Canadian "MREL Group of Companies Limited", based on a modern version of the rheostat measurement method. The study found that the introduction of a dry phase of 30% (at a density of 1.2 g/cm) in the composition of the NPGM contributes to an increase in the detonation velocity of explosives. The measurements also showed an increase in the detonation characteristics of the explosive with a decrease in its density to a value of r=1.17 g/cm. Therefore, with a decrease in the density to normal values (r=1.16-1.17 g/cm), we can expect the detonation velocity, which is stated in the technical specifications.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
