UNDER GRD MINE — ORIGINAL EDITABLE WORD R12.95
AU-R02 — SHOTCRETE DEFECTS, NCR AND CORRECTIVE ACTION REGISTER
A failed shotcrete thickness sample, uncontrolled rebound or inadequate ground support demands corrective action and reinspection, not a visual completion tick. AU-R02 is the genuine seven-row underground rehabilitation defects, nonconformances and corrective-action register.
WHERE AND WHEN THIS SOURCE REGISTER IS USED
Open it when rock-engineering, spray, substrate, curing, mix batch or dewatering controls fail inspection in a mine-approved work zone. Record MINE / AREA / LEVEL, WORK ORDER / MINE ZONE, DATE / SHIFT / PERMIT and CONTRACTOR SUPERVISOR so each defect remains tied to its actual installed lining and responsible shift.
SEVEN ORIGINAL TECHNICAL EVIDENCE CHECKS
1. Rock engineering approves design thickness, sequencing and substrate condition
2. Material mix, batch, expiry, set time and chemical hazards recorded
3. High-pressure hose, rebound and splash exposures controlled
4. Ventilation and dust/mist capture adequate for spray and curing operations
5. No workers exposed to unsupported ground during substrate preparation
6. Substrate tests, thickness checks, strength verification and cure holds defined
7. Runoff and washout protected against mine drainage and contamination
HOW TO COMPLETE THE GENUINE TABLE
Use the real four-column source table to enter MINING-SPECIFIC ITEM / EVIDENCE TO TRACK, DOCUMENT / RESULT / MEASURED VALUE and DATE / AUTHORITY / STATUS. Note the deficiency, applicable engineer or manufacturer requirement, corrective treatment, and true reinspection result. Keep evidence, certificates and source revisions.
DEFECTS, SIGN-OFF AND OPERATOR RE-ENTRY
Use OUTSTANDING DEFECT / NCR / REINSPECTION / RETENTION FILE REF and REVIEW / CLOSE-OUT AND EVIDENCE REFERENCES. Obtain contractor supervisor and host mine authority sign-off where required, with the actual Date / release reference. An incomplete result stays outstanding.
THE EDITABLE WORD SINGLE OR TWO FULL COLLECTIONS
This R12.95 source-original editable AU-R02 Word form is already included in the 371-document Underground Mining Checklist Package and the full 628-page Contractor H&S File. Owners of either parent should not buy it twice. Actual mine COPs, permits and engineering approvals govern use.
