304 / AS-R02 — TAILINGS & STOCKPILE DEFECTS, NCR AND VERIFIED CORRECTIVE ACTION
AS-R02 is the original editable Word defects and verified corrective action record for work beside tailings-facility perimeters, stockpiles and waste-rock dumps. Its seven source controls define what evidence the mine may need when a geotechnical-interface NCR is re-inspected.
THE REAL GEOTECHNICAL RISK
A damaged monitoring marker, blocked underdrain or unapproved trench can compromise evidence used to assess embankment performance. Correcting the visible fault must be supported by surveyed reinstatement, weather/diversion verification and responsible TSF engineer acceptance.
SEVEN ORIGINAL PRINTED EVIDENCE ROWS
1. Engineer/TSF authority signs reinstated drains, slopes and barriers. 2. Withdrawal route and downstream exposure communicated to crews. 3. Piezometers, instruments and survey markers protected against damage. 4. Buried drain, decant/underdrain and instrument locations surveyed before excavation.
5. Weather and stormwater diversion triggers tracked against overtopping risk. 6. Tipping, trenching and pipework inside engineering approval limits. 7. Crest, foundation, seepage, settlement and access controlled by current plan.
THE ORIGINAL FIELDS, EVIDENCE AND MINE AUTHORITY
Complete MINE / PIT / WORK AREA, WORK ORDER / MINE ZONE, DATE / SHIFT / PERMIT and CONTRACTOR SUPERVISOR. For every MINING-SPECIFIC ITEM / EVIDENCE TO TRACK enter DOCUMENT / RESULT / MEASURED VALUE and DATE / AUTHORITY / STATUS. The original has an OUTSTANDING DEFECT / NCR / REINSPECTION / RETENTION FILE REF field, not a separate issue-owner/cost schedule. Cross-reference the real NCR, source survey, repaired drainage, instrument inspection and engineer witness record; do not label a remedial item closed until owner release.
Use OUTSTANDING DEFECT / NCR / REINSPECTION / RETENTION FILE REF for unresolved work. Separate contractor and MINE RELEASE AUTHORITY signatures plus DATE / RELEASE REF prevent accidental self-release.
