Production and application in industrial conditions of non-explosive destructive mixtures
Bibliographic record
Abstract
In modern urban conditions of dense construction, as well as in the production of special works in the mining industry, new quality materials for non-explosive destruction of buildings, structures and rocks are required. Such material is non-explosive expanding mixtures (LDCs). LDCs are used in cases when the destruction of rocks by explosion unacceptable due to the dangerous consequences associated with the violation of stability of rock massif and negative seismic manifestations of the explosion. Non-explosive expanding mixtures are widespread in mining and construction works in many countries: the USA, Japan, Canada, the Czech Republic and others. They are used in the extraction of stone blocks, cutting of oversized, destruction of concrete structures, etc. Specialists of the academic University, research Institute and industry representative developed a product that is not inferior, and even superior to domestic and foreign analogues. The maximum developed pressure on the walls of the hole reaches 187.5 MPa. To date, the Russian market is represented by cheap, but lower in quality LDCs produced in China. Domestic development directly meets all the conditions of the Russian government Decree on import substitution. The article describes the main types of LDCs, the fundamental differences from analogues in the mode of production (firing). The mechanism of impact on the mountain range is considered. The main advantages of this material are indicated. The scope of the compositions is very extensive is the construction work in cramped conditions (ie. near buildings and structures, highways, industrial communications, settlements, in existing shops, etc.), mining of piece stone, crushing array (burrs, oversized, etc.), careful extraction of crystalline materials, work on dismantling of building structures, etc. it is Advisable to use these compounds in those places where it is not possible to use explosives.

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.
