AH-C01 — MINE DEWATERING TEN-POINT TASK PRESTART CHECKLIST
TEN actual original prestart points cover critical pump classification, inflow, backup, isolated energy, sump rescue, high-water alarms, overhead pipe support, potable backflow, approved sludge discharge and mine-authorised restoration.
WHERE THE ORIGINAL MINE WATER FORM APPLIES
Use before mine water work. Fill mine/site, contractor, zone, shift, work order and supervisor; follow actual owner approvals.
TEN GENUINE UNDERGROUND DEWATERING PRESTART CHECKS
1. Asset owner identifies whether pump/pipe forms a critical dewatering, emergency or fire-water system.
2. Underground flooding/water pressure and upstream inflow conditions reviewed with mine water engineer.
3. Redundant pumping and mine emergency controls confirmed before critical pump isolation.
4. Electrical, hydraulic, pressure, mechanical and check-valve trapped energy isolated.
5. Confined sump/tank entry has mine-specific atmospheric test, attendant and rescue.
6. Falling water level, inundation and overflow alarms monitored during outage.
7. Pipe hanging/support and corrosion/load assessment approved for underground roof/sidewall.
8. Backflow/cross-contamination and disinfection/quality controls accepted for potable water.
9. Test water/spills/sludge discharged by mine-approved route without harming production/escape.
10. Mine pump control and safe restoration acceptance documented before operation.
COMPLETING ACTUAL PRINTED WORD SOURCE FIELDS
For TEN RELEASE / VERIFICATION POINT source items, mark YES, NO or N/A with EVIDENCE / ACTION and formal mine release.
STOP-WORK AND MINE WATER SYSTEM RELEASE
The original RELEASE RULE requires every high-risk and mine-owned hold released; contractor check cannot replace the mine/host release.
EVIDENCE AND CONTROLLING MINE AUTHORISATIONS
Keep actual water-level and upstream inflow logs, pump duty/standby tests, authorised isolation, pressure/valve acceptance, flood escape, confined sump rescue and receiving mine owner sign-off with the original editable Word record. Completion does not independently authorise critical mine pump operation, mine technical duties or a work-area release.
