The archive contains four category names: diamond wire-saw machine, double-blade cutting machine, down-the-hole drill, and core-boring machine. This glossary preserves that four-part vocabulary while withholding the archived operating, blasting-specific, power, pairing, geology, and outcome claims.
Four archived terms and what each label does not establish
Diamond wire-saw machine
The term identifies an equipment family mentioned in the source. It does not provide a drive sequence, cutting method, material fit, wire specification, site arrangement, or expected result.
Double-blade cutting machine
The second label marks another archived machine category. It does not prove block size, cutting speed, site suitability, geology fit, current model identity, or a relationship with any other equipment.
Down-the-hole drill
This entry is retained strictly as a historical equipment name. Blasting purpose, hole dimensions, depth, rock classification, power classification, method, and workflow are excluded from the glossary.
Core-boring machine
The fourth heading records the category name found in the archive. It does not establish a purpose for a current project, a coring procedure, a machine pairing, material suitability, or an accepted outcome.
Category evidence register
| Register field | What may be recorded | What cannot be inferred |
|---|---|---|
| Archived label | The exact equipment-family name present in the historical page | A current model, configuration, or application decision |
| Current identity | A separately sourced first-party model document, if one is later supplied | That an old image or heading maps to the offered machine |
| Project context | A named site and accountable engineering scope outside this glossary | Geology fit, equipment pairing, or operating method |
| Claim status | Documented, unresolved, or excluded with a cited evidence owner | Performance, commercial, safety, or stability outcomes |
Source count conflict
The archived body presents four equipment sections but reportedly concludes with a count of three. This version follows the four visible category headings and records the inconsistent conclusion as a source limitation rather than silently reconciling it.
